Unsure of its purpose
Octane 104 is to boost the octane level of gasoline. So I did an experiment by using this product in my 2005 BMW which requires 91 octane fuel. I added 104 before I filled up the tank with 87 octane gasoline. I assumed that this product would increase the octane level to 91. I checked my fuel economy after I burned through the tank and found that my MPG was less than comparing it to using 91 octane fuel. I concluded that this does not give enough of an octane boost to replace the use of 91 octane fuel.

It's gettin there
Following the directions I poured the contents of the bottle into the almost empty tank of a 2004 Cayenne. The engine has been a bit rough idling and at speed for about a month and I was counting on the 104 to clean up the system a bit. Drove for about 150 miles and at the end of the trip the idle seemed to smooth out ever so slightly but I didn't really see any added benefits to performance or mileage. I would have to try another bottle to see if it continues to improve idle and or performance.

Increased Power and Mileage on 78 Dodge Van
I have a 78 Dodge Van that does not like the current fuel options at the pumps. She does not run well or get great mileage with regular gas or even premium. I started adding the 104+ Octane Boost to the tank when we fill it up. My wife is the one who drives it on trips. She knows the van well. She said it was running better, smoother and without hesitation. Also that we were getting better gas mileage as well with it. From now on at every fill up she gets a bottom of 104+. Great product.

104 Octane Boost
Received this product June 23, 2016, and put it my 07 Shelbt GT Mustang. I found that it did boost the power and overall performance of the motor.

It works
I like to experiment, so I put 2oz. of the 104 Octane in my lawn tractor 1 gallon tank. It ran better than it has in years - (15 yr old).

Octane booster, really?
I researched this "octane booster" before I used it and found out that it only raises the octane about .5 points, not to the 104 octane suggested on the package. I guess if it cleans injectors and removes water from the fuel that is good, but for boosting octane it is a flop.

The Best!!!
104+ octane boost is the only fuel treatment i use. It works so well. The unique formulation is extremely effective. The number of Proprietary ingredients gives me great confidence in its ability to do what it's says on the bottle. It has a great price as well. The mpg on my Oldsmobile Cutlass increased by 4% after 1 use. Thank you for making the BEST Fuel additives in the nation!

Give Your Engine a Boost
I have been using Gold Eagle 104 Octane Boost for a few years now. The first time that I used it I was travelling to a car show in West Virginia. I was towing a trailer and needed all the help that my car could get to climb the mountains. My car had no trouble after adding the 104 Octane Boost and my gas mileage improved also. I love this stuff and use it frequently.

Skeptical before use
I didn't think this gas additive would make a difference with my 20 year old mower or my weed eater grass trimmer. This spring, I mixed up a batch to use with my lawn equipment and WOW- it really made a performance difference. Both engines started with the first pull. The engines idle smoother and have better throttle responses.

Octane Boost works!
Wow! My ZZ4 (355HP 350 SB) would ping even on 93 octane gas. There's no ping after adding Octane Boost. I would like to see a better dispensing method as my tank fill location is in the bed of a (street rod) pickup and it was difficult NOT to spill when adding it to the tank (maybe a flip-top squeeze cap like syrup bottles).

A bit more power.
I planned a trip to a popular mountain road in North Carolina this week end so it was a perfect time to try 104+. This is a locally famous road that is 11 miles long with 318 curves. You're either on the gas or the brakes. My car accelerated harder and smoother than usual. I can only attribute it to your product. Thanks!

Saves Money!
I just received the Octane Booster and decided to use it in my truck. Unless I use top grade premium unleaded gas, my truck will "ping" and pre-detonate. I used the octane booster and had no pinging and it seemed like a lot more power. Using this product saved me about $7.50 by not having to buy premium unleaded gas.

Really Helps.
I used a bottle to see if the reviews that I had read were true or not. I'm pretty skeptical by nature but was pleased with the results.
My old 85 Chevy pickup truck ran better than ever. It ran smoother and had more get up and go. I didn't check the gas mileage.

No more knock!
Used just a little of this in my highly modified (built) Harley and this eliminated the pre-detonation (spark knock). Saves me a trip to the marina for the high octane stuff. It's supposed to also help clean fuel injectors but only time will tell on that opinion.

Kick in the pants
Added the booster to a Tank of 86 octane because that is ALL they had on my last road trip in the Vette. Have always used 91 or 93 if I can find it, but I couldn't tell the difference. I will keep a bottle for emergency use from now on.

Always use it in bike
I don't notice a huge difference using the booster in the car, but even using the ethanol infused 92 octane, I really feel the difference on my Harley. More power, more responsive and anything I can do to fight the ethanol is a plus.

Great for my Harley
I use this in my Harley-Davidson while touring. It comes in especially handy for the times when premium unleaded gas is not available. Also improves the mileage and bike runs great with no pinging or knocks.

A must for your classic muscle car!
Used 104+ Octane Boost in my '66 Sunbeam Tiger and noticed a significant difference in performance. If you're putting today's lower-octane fuels into your '60s muscle car, you need this product!

Engine improvement
104 Octane Boost appeared to provide an increase in engine performance. I didn't confirm a mpg improvement; I need to try the product a couple more times to provide a statistical assessment.

Power!
After adding octane boost 104 to my 2012 Lincoln MKS, I immediately noticed a surge of power when I hit the gas pedal. The hesitation is gone and so are the cars in my rear view mirror!

Better Performance
I have been suffering with poor octane performance with Mobile and Shell 93 Octane gas. This product has really improved my SUV's performance. I am very happy with 104 Octane Boost.

Good fuel additive
I have a 1969 Camaro with a relatively higher compression ratio engine that I like to use this in. I don't have any detonation so I'd say it's helped the fuel.
