STA-BIL Fuel Stabilizer

Q: Where can I purchase STA-BIL® Fuel Stabilizer?
A: See list of retailers that carry STA-BIL® Fuel Stabilizer on the STA-BIL® brand “Where to Buy” page of this site, or call 800-367-3245.

back to top


Q: How long will STA-BIL Fuel Stabilizer® keep fuel fresh?
A:
STA-BIL® Fuel Stabilizer will keep fuel fresh for up to 12 months, guaranteed. Depending on the quality, type and
source of the gasoline, as well as storage conditions, doubling the dosage rate of STA-BIL
® brand could prolong this storage
time to up to 2 years. However, any gasoline stored for more than 12 months will tend to lose volatility (ignitability),
which could lead to hard starting or no start conditions after this long storage period. NO additive, STA-BIL
® brand included,
will prevent volatility loss in fuel. To reduce fuel volatility loss during storage, we recommend filling your tank at least
95% fulll with fresh fuel and STA-BIL
® brand, and store in cool conditions away  from direct sunlight if possible.
If you forget to stabilize your fuel prior to storage and do experience problems starting your equipment after storage,
we recommend trying our StartYourEngines!® Fuel System Revitalizer
product.

back to top


Q: What is the shelf life of STA-BIL® Fuel Stabilizer?
A: The shelf life of all STA-BIL® brand products is 2 years after the bottle has been opened, provided it has been tightly capped and stored in a cool, dry place.  If the product has not yet been opened, you should use the color of the fluid as an indicator. If the product is still bright red, it is fine to use. If the product has turned to av ery dark red (or brown) color, we recommend purchasing a new bottle.  It will not harm anything if you use an old bottle of STA-BIL® brand, it just may not be as effective.

back to top


Q: How much STA-BIL® Fuel Stabilizer should I add to fuel?
A: One ounce (30mL) of STA-BIL® Fuel Stabilizer for every 2 ½ gallons (9.5 L) of gasoline, gasoline/oil mixtures, or ethanol blends is the recommended dosage level.

back to top


Q: Is STA-BIL® Fuel Stabilizer safe to use in all gasoline, including gasoline/oil mixtures and ethanol blends (including gasoline containing ethanol)?
A: Yes, All STA-BIL® brand products are effective with all Ethanol blended fuels, including E-10, E-15, and E-85.

back to top


Q: Is STA-BIL® Fuel Stabilizer safe for fuel injectors and catalytic converters?
A: STA-BIL® brand is safe to use in both fuel injected and carbureted engines, and will not damage catalytic converters or oxygen sensors. STA-BIL® Fuel Stabilizer prevents the formation of gums and varnish that can clog fuel injectors, and actually contains a fuel injector cleaner to further improve your engine’s performance.

back to top


Q: Can I use STA-BIL® Fuel Stabilizer in both 2-cycle (gas and oil mixture) and 4-cycle engines? What about the number of engine cylinders (1, 2, 4, 6 or 8 cylinders)?
A: Yes, STA-BIL® Fuel Stabilizer works equally well for both 2-cycle (gas and oil mixture) and 4-cycle engines. STA-BIL® brand can be used in engines with any number of cylinders (e.g. 1, 2, 4, 6 or 8 cylinders).

back to top


Q: I have some gas in a tank that has been there more than 2 months. Will STA-BIL® Fuel Stabilizer make this old gas like new?
A: No, STA-BIL®Fuel Stabilizer will not restore or improve old gasoline. It will, however, stop it from degrading further. The best thing to do is treat the fuel with STA-BIL® brand as soon as you buy it.

Depending on the quality, type and source of the gasoline, as well as storage conditions, doubling the dosage rate of STA-BIL® brand could prolong this storage time to up to 2 years. However, any gasoline stored for more than 12 months will tend to lose volatility (ignitability), which could lead to hard starting or no start conditions after this long storage period. NO additive, STA-BIL® brand included, will prevent volatility loss in fuel. To reduce fuel volatility loss during storage, we recommend filling your tank at least 95% fulll with fresh fuel and STA-BIL® brand, and store in cool conditions away from direct sunlight if possible.

back to top


Q: I put STA-BIL® Fuel Stabilizer in gas more than 12 months ago. If I put more STA-BIL® brand in will it extend the time that the gas is still usable?
A: No, re-treating already stabilized fuel that has been stored for a significant period of time will not significantly prolong the life of, nor improve the fuel.

back to top


Q: What if my gas has already gone stale (i.e. has gummed up)?
A: If the engine starts, you should fill your tank with fresh gas and use a fuel injector cleaner product (such as 104+ Octane Boost®). If your engine does not start, due to the fuel being stale, we recommend you trying our Start Your Engines!® Fuel System Revitalizer product.

back to top


Q: When should I use STA-BIL® Fogging Oil?
A: Use STA-BIL® Fogging Oil when an engine is not going to be run for 30 days or more. In as little as 30 days the protective oil layer in the engine can drain away and evaporate leaving bare metal surfaces susceptible to corrosion damaging the engine and reducing performance and engine life.

back to top


Q: How do I use STA-BIL® Fogging Oil?
A:
  1. Start the engine and remove the air filter.
  2. Spray Fogging Oil into air intakes of running engine.
  3. Shut off engine after 10 seconds (often engine will choke itself off)*.
  4. Remove spark plugs.
  5. Attach extension tube and spray Fogging Oil into each cylinder for 3 seconds.
  6. Replace spark plugs.
  7. * For maximum protection you can also coat the cylinders directly in addition to steps 1-3.

back to top


Q: How do I remove a spill-related red stain?
A: If spilled immediately blot-up STA-BIL® Fuel Stabilizer with a paper towel. If a stain remains, moisten a paper towel with mineral spirits (common paint thinner) or dry cleaning fluid available at most hardware stores and home centers. Test for color fastness, then place moistened towel on the stained area for 30 seconds -- this may be repeated twice. Rinse area with Isopropanol (common rubbing alcohol).

back to top


Q: Does STA-BIL boost Octane?
A: No. STA-BIL will not boost the octane of the fuel. We recommend trying our 104+ Octane Boost products if you need to boost the octane of your fuel.

back to top


Q: What is the difference between STA-BIl Fuel Stabilizer, Marine Formula STA-BIL, and the new STA-BIL Ethanol Treatment products?
A: STA-BIL® Fuel Stabilizer is designed for use during STORAGE of any gasoline equipment or vehicle stored for 30 days or more, or used infrequently. It will keep gas fresh for 12 months, and help prevent corrosion, and gum and varnish formation. It is effective in all gasolines, including Ethanol blends, including E-85.
Marine Formula STA-BIL® Ethanol Treatment was designed for use at every fill up for marine engines (boats, jetskis) to protect against the damaging effects experienced when using Ethanol blended fuels -- including corrosion caused by water attraction, and fuel system plugging caused by deposit loosening.
New STA-BIL Ethanol Treatment is designed for use at every fill up for all gasoline automotive and small engines for protection against these same problems.

back to top


Q: Can I use STA-BIL Fuel Stabilizer in Diesel fuel?
A: Diesel fuel systems and gasoline systems are designed differently, and require different additives. In addition, regulations issued by the EPA over the last few years have resulted in diesel fuel reformulations (to Ultra Low Sulfur Diesel fuels), creating a need for more specialized diesel specific additives. In 2010, we created a special Diesel Formula STA-BIL, designed specifically to address problems related to the new Ultra Low Sulfur Diesel fuels and new diesel engine technologies, including thermal oxidation (heating of fuel), sludge and sediment formation, corrosion, and lubricity issues. It also helps remove water from the fuel. Using Regular STA-BIL in Diesel will not harm the diesel system in anyway, but will not be effective. In addition, the red dye in Regular STA-BIL can cause potential legal issues if used in On-Road Diesel Fuel, as Off-Road diesel fuel is purposely dyed red for tax purposes.

back to top


Q: I've heard that 1) The Old STA-BIL Fuel Stabilizer is no good with the new fuels. 2) Red STA-BIL Fuel stabilizer gums up carburetors/engines 3) Old STA-BIl no longer works. 4) A mechanic told me to stop using STA-BIL, and that I should use a different STA-BIL product now.
A: STA-BIL Fuel Stabilizer is designed to be used during storage or infrequent use in any gasoline engine, and will keep any gasoline (even Ethanol blends, up to E-85) fresh for up to 12 months. The STA-BIL® formula was improved over a year ago to include additional corrosion protection to protect against the damaging effects experienced when using Ethanol blended fuels. STA-BIL is compatible with ALL 2 and 4 cycle engines, and will absolutely NOT harm any components in an engine. The best way to protect your fuel system from Ethanol blended fuels related issues year-round (not just during storage), we recommend using new STA-BIl Ethanol Treatment. For Marine engines, such as a boat or jet-ski, we recommend Marine Formula STA-BIL Ethanol Treatment which has been specifically formulated for the extra severe conditions faced by these engines.

back to top


Q: Should I stop using STA-BIl Fuel Stabilizer and use the new STA-BIl Ethanol Treatment or Marine Formula STA-BIL instead?
A: There are specific needs for each product. As a general guideline, if you are STORING your gasoline vehicle or equipment for 30 days or more, we recommend you use Red STA-BIL Fuel Stabilizer. For EVERYDAY PROTECTION against Ethanol blended fuels in your Marine gasoline engine, we recommended using Marine Formula STA-BIL at every fill up during the season. For protection in all other non-marine gasoline vehicles, use new STA-BIL Ethanol Treatment at every fill up. For Diesel vehicles and equipment, use Diesel Formula STA-BIL Fuel Stabilizer.

back to top


Q: How does your product compare to StarTron?
A: Chemists with over 75 years combined fuel additive experience have developed STA-BIL®'s fuel additive formulations. Over 100 engine and equipment manufacturers recommend STA-BIL® product by name. No other fuel additive manufacturer can claim this level of trust from the people that design, build and service engines.

back to top


Q: Can "Non-Ethanol" AND Ethanol fuel be mixed together on a consistent basis? If so, what are the side effects?
A: It is safe to mix Ethanol and non-Ethanol blended fuels, but only if the owner's manual of your equipment or vehicle recommends/allows the use of Ethanol blended fuels. Always check your owner's manual for the recommended type of fuel to use in your equipment/vehicle.

Marine Formula STA-BIL

Q: Where can I purchase MARINE Formula STA-BIL®?
A: See the list of retailers that carry MARINE Formula STA-BIL® on the STA-BIL® brand “Where to Buy” page of this site, or call 800-367-3245.

back to top


Q: How much of the gasoline currently sold in the United States has some percentage of ethanol blended into it?
A: Currently almost HALF of the gasoline sold in the United States has some percentage of ethanol blended into it, and that percentage is expected to grow significantly over the next five years as additional supplies of ethanol become available to blend into gasoline. Ethanol is blended together with gasoline at the local fuel terminals, and then the tankers deliver the fuel to the local retail locations. Ethanol is stored separately from gasoline prior to blending it together at the fuel terminals, since ethanol attracts water, and also requires special corrosion-resistant pipes and tanks to store it.

back to top


Q: Can I use MARINE Formula STA-BIL® Ethanol Treatment in my marine engine(s) and also in my other gasoline-powered outdoor equipment engines too?
A: MARINE Formula STA-BIL® was designed specifically for use in Marine Engines., but it is safe to use in all 2 and 4-cycle gasoline equipment if desired.

back to top


Q: Is MARINE Formula STA-BIL® Ethanol Treatment safe to use?
A: MARINE Formula STA-BIL® is completely safe to use in any engine powered by gasoline, gasoline/oil mixtures, and ethanol blends. It contains no additives that could harm a fuel tank or fuel lines, or an engine, fuel injectors or intake valves. Use of STA-BIL® brand will not void any engine warranty. In addition, over treatment is safe and will not harm engine.

back to top


Q: How much MARINE Formula STA-BIL® should I add to fuel?
A: For everyday in-season engine performance improvement and protection, use 1 ounce (30mL) in every 10 gallons (37.9 L). For seasonal storage and for fuel system clean-up, use 1 ounce (30mL) of MARINE Formula STA-BIL® in 5 gallons (18.9 L). Again, over treatment is safe and will not harm engine.

back to top


Q: What is the difference between Marine Formula STA-BIIL®, STA-BIL® Fuel Stabilizer, and the new STA-BIL® Ethanol Treatment products?
A:  Marine Formula STA-BIL® Ethanol Treatment was designed for use at every fill up for marine engines (boats, jetskis) to protect against the damaging effects experienced when using Ethanol blended fuels -- including corrosion caused by water attraction, and fuel system plugging caused by deposit loosening.
STA-BIL® Fuel Stabilizer is designed for use during STORAGE of any gasoline equipment or vehicle stored for 30 days or more, or used infrequently. It will keep gas fresh for 12 months, and help prevent corrosion, and gum and varnish formation.
New STA-BIL® Ethanol Treatment is designed for use at every fill up for all gasoline automotive and small engines for protection against these same problems.

All STA-BIL® brand products are effective in all gasolines, including Ethanol blends, including E-85.

back to top


Q: What is Phase Separation? Can your product PREVENT phase separation? What if fuel has already Phase Separated?
A: Phase separation occurs when the Ethanol in the fuel absorbs more water than it can naturally hold, and separates to the bottom of the tank along with the water. This results in two solutions (water/Ethanol mixture, and gasoline). A water/Ethanol solution is extremely damaging to your engine and fuel system, and no engine manufacturer recommends forcing water through the engine. Once phase separation has occurred, NO fuel additive nor anything else can be done or added to reverse it. The fuel tank should be drained.

back to top


Q: How does Marine Formula STA-BIL® Ethanol Treatment handle water?
A: Ethanol blended fuels can naturally hold up to 4 tbsp of water per gallon (about 0.5%) before phase separation occurs. Marine Formula STA-BIL® Ethanol Treatment contains a chemical that will absorb an additional fraction of a percent of water above this amount (around 0.2%), by bonding with the water molecules, allowing this additional amount to pass safely through the engine and out through the tailpipe. Any amount above this will drop to the bottom and phase separate. Removing large amounts of water (more than 0.75%) through bonding will cause poor power/acceleration and sometimes cause the engine to quit. Additionally, it can cause catastrophic engine damage. No engine manufacturer recommends removal of these large amounts of water through bonding.

back to top


Q: If I have water in my tank, what should I do, should I drain it?
A: In a Marine engine, during usage of that equipment, any water that has not been safely carried through the fuel will most likely be taken out by the fuel/water separator). If you believe you have water in a fuel tank that has been sitting, we recommend draining the tank, and refilling with fresh fuel and Marine Formula STA-BIL® Ethanol Treatment.

back to top


Q: How does your product compare to StarTron?
A: Chemists with over 75 years combined fuel additive experience have developed STA-BIL® brand's fuel additive formulations. Over 100 engine and equipment manufacturers recommend STA-BIL® brand product by name. No other fuel additive manufacturer can claim this level of trust from the people that design, build and service engines.

back to top


Q: Does your product protect the fuel lines? Does it protect rubber gaskets and plastic parts? What parts of the Fuel system does Marine Formula STA-BIL® protect, and how?
A: NO additive, including Marine Formula STA-BIL® can protect rubbers and plastics that are not designed for exposure to Ethanol or other chemicals found in gasoline. Marine Formula was designed to protect against corrosion on any metal components of the fuel system. This product is also an excellent fuel system cleaner, removing deposits that have accumulated on the carburetor, fuel injectors or intake valve.

back to top


Q: Does Marine Formula STA-BIL® have the same stabilization characteristics as STA-BIL® Fuel Stabilizer?
A: STA-BIL® Fuel Stabilizer is the recommended additive for extended storage. Marine Formula STA-BIL® can stabilize fuel if used in the proper concentration for up to 12 months, but is designed for EVERY DAY USE to protect against the damaging effects experienced when using Ethanol blended fuels.

back to top


Q: Do I need to use Marine Formula STA-BIL® in dry/arid parts of the U.S. such as the Southwest?
A: Water vapor is present in ALL areas of the continental U.S.,even dry climates, so Marine Formula STA-BIL® should be used at every fill up in any Marine engine -- to protect against corrosion, as well as to help clean out your fuel system.

back to top


Q: When using Marine Formula STA-BIL®, does it preserve the Octane rating of the fuel?
A: No. We recommend trying 104+ Octane Boost® if you need to boost the octane of your fuel.

HEET

Q: How does HEET® brand work?
A: HEET® brand contains a special additive and methanol. When HEET®brand is added to the gas tank, it sinks to the bottom and mixes with any water. Since both HEET® brand and water are heavier than gasoline, they go to the bottom of the gas tank. HEET® brand absorbs water and keeps it from freezing, and blocking the flow of gasoline through the gas line and fuel pump. When the vehicle is started, the additives, methanol, water, and gasoline are consumed during combustion inside the engine.

back to top


Q: How does ISO-HEET® brand work?
A: ISO-HEET® brand contains isopropanol and special additives including Fuel Injector Cleaner. When ISO-HEET® brand is added to the fuel tank, this formula remains in the solution with the gasoline, and absorbs five times more than regular gas-line antifreeze. Any water in the gas tank mixes with the ISO-HEET® brand, preventing the water from freezing in winter. ISO-HEET® brand also removes water and condensation in warm, wet weather. Then the entire mixture of gasoline, ISO-HEET® brand and water are burned during combustion inside the engine. ISO-HEET® brand cleans fuel injectors and carburetors for fast starts and smooth-running engines year round.

back to top


Q: Can I use HEET® brand in 2 cycle or diesel engines?
A: No, only use HEET® brand (in the yellow bottle) in 4-cycle gasoline engines. However, ISO-HEET® brand (in the red bottle) can be used in any type of internal combustion engine (2 cycle, 4 cycle and diesel).

back to top


Q: Will HEET® brand or ISO-HEET® brand harm my catalytic converter or fuel injectors?

Q: Will HEET® brand harm my carburetor or fuel system?
A: No, HEET® brand will not harm your carburetor or fuel system when used as directed.

back to top


Q: Will HEET® brand work when the gas line is already frozen?
A: Maybe, but not always, it depends where the gas line is frozen. You can try adding a bottle of HEET® brand, waiting 15-20 minutes and then trying starting your engine. If that does not work, you should have your car moved to a warm garage to thaw out. To avoid this from happening, you should always use HEET® brand as a preventative measure before temperatures are expected to fall below 32°F (0 °C).

back to top


Q: How many bottles of HEET® brand or ISO-HEET® brand should I use at one time?
A: One bottle of HEET® brand or ISO-HEET® brand treats up to 20 gallons (75.7 L) of gasoline. You should not use more than 2 bottles in a 20-gallon (75.7 L) gas tank, 3 bottles in a 30-gallon (113.6 L) gas tank. HEET® brand and ISO-HEET® brand are safe to use in every tankful, in all seasons, all year-round.

back to top


Q: Should I add HEET® brand or ISO-HEET® brand before or after I fill up?
A: Either way – adding HEET® brand before or after you fill your tank with gasoline works equally well.

back to top


Q: What is the shelf life of HEET® brand and ISO-HEET® brand?
A: Unopened bottles of HEET® brand and ISO-HEET® brand have an indefinite shelf life provided the foil safety seal has not been broken. During storage, the bottles may swell and appear pressurized. This distortion is a result of vapor pressure formed by the formula stored at higher temperatures (which can happen in your garage or the trunk of your car). When this happens, the product is still fine to use. It does not diminish the product’s performance.

DieselPower!

Q: Can I use DieselPower!® brand products every time I fill up? Can using more than what is recommended on the label damage my vehicle?
A: All DieselPower!® brand Fuel Additives are compatible with each other, and may be blended together. Added dosing of cetane improvers and anti-gel will provide additional benefits in higher concentrations. "Double-dosing" of fuel injector and complete fuel system cleaner (using more than directed on the label) is not damaging — although it may not provide additional benefit.

back to top


Q: What is the difference between the Complete Fuel System Treatment, and the Fuel Injector Cleaner?
A: The Complete Fuel System Treatment contains cetane improver, anti-gel, lubricity and detergent additive.  The Complete Fuel System Treatment is stronger and faster acting product. This product cleans the complete fuel system, ports & passages, while the Fuel Injector cleaner is specially formulated to clean only the diesel fuel injectors.

back to top


Q: Why do I need to use an Anti-Gel product, and when should I use it?
A: Diesel Fuel contains hydrocarbon waxes that can crystallize and form wax crystals, which can block diesel fuel lines and fuel filters. Anti-gel products stop or prevent this from happening. To be effective, anti-gels must be added to fuel before the fuel gels at a temperature of > -15ºF. When added correctly, DieselPower!® Anti-Gel will allow diesel fuel to continue to flow even at -25° F (-31.7°C)  or lower.

back to top


Q: I did not use an DieselPower!® Anti-Gel product, and now my vehicle will not start. Can I still add the DieselPower!® Anti-Gel & Fuel Treatment?
A: You can still add this product, although it will not dissolve the wax that has already gelled in your fuel. You must add the Anti-Gel product before gelling for it to be effective above 15ºF. If you have reason to believe your diesel fuel has gelled, move your vehicle to a warm garage, and wait for the wax to dissolve.

back to top


Q: When do I use the DieselPower!® Performance Improver & Cetane Booster? Can this be used year round?
A: This product should be used any time that more noise is noticed on acceleration, or you notice white smoke when your vehicle is started. You can also use this product to obtain maximum power while towing.

Q: What is the shelf life of the DieselPower!® brand products?
A: DieselPower!® brand products have an indefinite shelf life, provided the cap has not been removed.

back to top


Q: Why does the DieselPower!® brand product I saw in the store or purchased have a diesel additive compliance sticker on the side of the bottle?
A: On June 1, 2006, the Ultra Low Sulfur Diesel Fuel (ULSD) regulation went into effect. This regulation, mandated by the EPA, was created to reduce emissions in 2007 or newer model diesel vehicles by lowering the sulfur content of diesel fuel to less than 15 parts per million. This regulation requires that ALL diesel fuel additive products must be labeled or stickered stating whether the product complies with the new ULSD regulations (contains less than 15 ppm sulfur), or does not comply (contains more than 15 ppm sulfur). Because the stickered DieselPower!® brand products contained more than 15 ppm sulfur, they are required to have the does not comply sticker. However they are totally safe to use in ALL 2006 and older model diesel engines.

DIESEL Formula STA-BIL®

Q: Why should I use DIESEL Formula STA-BIL Fuel Stabilizer®?
A: In 2006, the EPA mandated the reformulation of diesel fuels, reducing sulfur content to less than 15 ppm. These newly reformulated diesel fuels, called Ultra Low Sulfur Diesel and Bio-Diesel, are less stable than diesel fuels of the past. The reduction in sulfur also means less lubrication to protect the diesel engine from wear, leading to more breakdowns and major engine problems. Diesel Formula STA-BIL® is specially formulated to help prevent sludge and sediment formation and the darkening of diesel fuel. Diesel Formula STA-BIL® contains high levels of detergents and lubricity agents, and when used regularly, haleps remove these sediments as well as any engine deposits that may have already formed, in addition to lubricating critical fuel system components to kepp your diesel engine running like new.

back to top


Q: Does DIESEL Formula STA-BIL® also help remove water? How? Why is this important?
A:

Although water attraction can occur within the fuel tank at any time, when diesel fuel is stored for long periods, it is more likely to draw in moisture from the air. Which means the fuel is more prone to fungus, algae and bacterial growth. Algae can grow rapidly within the fuel and fuel system if there is any water within the fuel or tank. This growth can lead to a gummy mess within your fuel tank -- clogging the entire system, and if not properly cleaned and maintained, causing your diesel engine to run poorly, if at all.

Diesel Formula STA-BIL® helps remove water from the diesel fuel, eliminating the environment in which fungi and algae require to grow in. Diesel STA-BIL® demulsifies the water (breaks the water into small droplets) dropping it to the bottom of the fuel tank, where the fuel/water separators remove the water from the fuel, allowing the fuel to move safely through the fuel system.  By removing the water before the fuel flows through the fuel system, also helps protect against corrosion.

back to top


Q: In what types of fuel can DIESEL Formula STA-BIL® Fuel Stabilizer be used in?
A: DIESEL Formula STA-BIL® is safe to use in ALL Diesel Fuels, including Ultra Low Sulfur Diesel and Bio-Diesel blends.  It is also safe to use in ANY Diesel Engine, including Marine and Agricultural equipment.

back to top


Q: Can you use DIESEL Formula STA-BIL® in Home Heating Oil?
A: While this product was not specifically developed for this purpose, it is safe to use Diesel Formula STA-BIL® in Home Heating Oils.  It will work well at keeping the burners clean, removing any water in the fuel and will also help stabilize the fuel, if stored for periods of time.

back to top


Q: I thought Regular (Red) STA-BIL® Fuel Stabilizer worked in Diesel Fuel, how is Diesel Formula STA-BIL® better?
A: Diesel fuel systems and gasoline systems are designed differently, and require different additives. In addition, regulations issued by the EPA over the last few years have resulted in diesel fuel reformulations (to Ultra Low Sulfur Diesel fuels), creating a need for more specialized diesel specific additives. In 2010, we created a special Diesel Formula STA-BIL, designed specifically to address problems related to the new Ultra Low Sulfur Diesel fuels and new diesel engine technologies, including thermal oxidation (heating of fuel), sludge and sediment formation, corrosion, and lubricity issues. It also helps remove water from the fuel. Using Regular STA-BIL® Fuel Stabilizer in Diesel will not harm the diesel system in anyway, but will not be effective. In addition, the red dye in Regular STA-BIL® Fuel Stabilizer can cause potential legal issues if used in On-Road Diesel Fuel, as Off-Road diesel fuel is purposely dyed red for tax purposes.

back to top


Q: How much DIESEL Formula STA-BIL® should I add to fuel?
A: We recommend using DIESEL Formula STA-BIL® at EVERY FILL up to protect your fuel system year-round from sludge and sediment formation, water, corrosion, and breakdown of the fuel.  For use in every tank, use 1 ounce in every 10 gallons of fuel. If using product only during storage, use 1 ounce in every 5 gallons of fuel.

back to top


Q: Where can I purchase DIESEL Formula STA-BIL®?
A: DIESEL Formula STA-BIL® is available at many leading marine retailers, as well as farm and fleet retailers.  Refer to our web site: www.sta-bil.com or call toll free 800-367-3245.

New STA-BIL® Ethanol Treatment is designed for use at every fill up for all gasoline automotive and small engines for protection against these same problems.

back to top


Q: Can I and should I use the new STA-BIL® Ethanol Treatment and STA-BIL® Fuel Stabilizer in the same tank of fuel to store E-10 fuel?
A: If you are storing a gasoline vehicle or piece of equipment for 30 days or longer, we recommend you continue to use STA-BIL® Fuel Stabilizer. It will keep fuel fresh for up to 12 months.

If you are looking for an additive that will help protect your vehicle or equipment from Ethanol-blended fuels, you should be using new STA-BIL® Ethanol Treatment more regularly to help further protect against corrosion, clean your fuel system, and remove water at every fill up. 

It is safe to use both products together at the recommended dosage rates if desired.

back to top


Q: Does the original STA-BIL® Fuel Stabilizer no longer work with Ethanol Fuels?
A: This is absolutely NOT true. STA-BIL® Fuel Stabilizer is effective in storing gasoline for up to 12 months in ALL Ethanol blended fuels, up to E-85.  It prevents gum and varnish formation/build-up caused by the breakdown of fuel and also helps prevent corrosion from moisture/humidity during storage.  For more information on STA-BIL® Fuel Stabilizer please review those FAQ’s above.
