#1 Selling Gas-Line Antifreeze & Water Remover
HEET is the #1 Selling Gas-Line Antifreeze & Water Remover. It removes water from the fuel system to prevent gas-line freeze-up and harmful rust and corrosion. Iso-HEET is the #1 Selling Premium Fuel-line Antifreeze, Water Remover & Injector Cleaner. It absorbs 5 times more water than regular gas-line antifreeze, while it cleans fuel injectors and carburetors. It’s designed for use year-round in ALL 2-cycle and 4-cycle gasoline engines and diesel engines.
HEET
Q: How does HEET work?
A: HEET contains special additives and methanol. When HEET is added to the gas tank, it sinks to the bottom and mixes with any water. Since both HEET and water are heavier than gasoline, they go to the bottom of the gas tank. HEET 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.

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

Q: Will HEET 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, 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 as a preventative measure before temperatures are expected to fall below 32°F (0 °C).

Q: How many bottles of HEET or Iso-HEET should I use at one time?
A: One bottle of HEET or Iso-HEET 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 and Iso-HEET are safe to use in every tankful, in all seasons, all year-round.

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

Q: What is the shelf life of HEET and Iso-HEET?
A: Unopened bottles of HEET and Iso-HEET 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.
