Rated 4.3 out of 5 by 49 reviewers.
Rated 5 out of 5 by noticeable difference! Added to a tankful of gas in a '76 ALFA. Noticed a difference in quick starting and better throttle response immediately. [This review was collected as part of a promotion.] July 7, 2016
Rated 5 out of 5 by 104+ Octane Boost I decided to give 104+ Octane Boost a try in my '03 Land Rover Discovery. Anytime I run premium gas in it, it always seems to get better mileage. I normally see a slight improvement with 93 octane pump gas, I was hoping to see a more noticeable improvement with the 104+ Octane Boost. With nearly 3/4 of the treated tank used, I can say with certainty that I'm seeing a gain in excess of 3mpg. That's almost 65 extra miles with a full tank used. I also noticed less hesitation in the throttle response. Overall, the improved mileage and smoother running engine make 104+ Octane Boost a winner with me.

Rated 5 out of 5 by 104 Octane Booster Engine ran smoother and cooler, even adding to non ethanol fuel. [This review was collected as part of a promotion.] July 5, 2016
Rated 4 out of 5 by 104 octane Added this to my 2002 5.4 F150 for a 250 mile trip. The truck ran great with this additive. The engine ran smooth and strong. [This review was collected as part of a promotion.] July 4, 2016
Rated 4 out of 5 by Tough One to Review Out of the three products I have reviewed this is the most difficult. I drive a 2009 Dodge Challenger SRT8 ( 6.1 L) and run a 93 octane gasoline in it. After adding the 104+ Octane Boost I found it very difficult to notice any difference in performance or gas mileage improvement. I'm confident that there was probably some but it just wasn't noticeable to me. Having said this, I still rated the product with 4 of 5 stars because of the other benefits it is supposed to provide ( clean injectors, remove gasoline deposits and provide an anti friction barrier to the piston walls). Again this is something difficult to evaluate however I believe in the " quality of products" that Gold Eagle provides based on my experience with their other products and this is a claim that they make. These benefits, as stated, are difficult to evaluate and may or may not be realized after only one full tank of gas so I will continue to use the product. In retrospect another test that I could have done would have been to reduce the octane level I purchase ( say to 87) and see if the addition of 104+ at least maintained the car's performance but I didn't think of this until later. If this works it would negate the additional cost of the 104+and you would receive the additional benefits of injector cleaner, remove gasoline deposits and provision of a friction barrier!!!

Rated 5 out of 5 by 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! [This review was collected as part of a promotion.] July 1, 2016
Rated 5 out of 5 by You have to try it! I put a bottle in this week and received increased gas mileage with improved acceleration on my 2015 Jeep Grand Cherokee. [This review was collected as part of a promotion.] July 1, 2016
Rated 5 out of 5 by 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. [This review was collected as part of a promotion.] July 1, 2016
Rated 4 out of 5 by Title works for me Used the product in my Lincoln LS V8, seems to run better and mileage has increased slightly. [This review was collected as part of a promotion.] July 1, 2016
Rated 4 out of 5 by 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. [This review was collected as part of a promotion.] July 1, 2016
Rated 4 out of 5 by works really good ! got this a week ago and added it to the gas for my old car! and it helped with the starting! makes today's gas Better! [This review was collected as part of a promotion.] July 1, 2016
Rated 5 out of 5 by 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.

Rated 5 out of 5 by 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! [This review was collected as part of a promotion.] July 1, 2016
Rated 5 out of 5 by I can feel the difference I could feel the difference in power! The idle was smoother! [This review was collected as part of a promotion.] July 1, 2016
Rated 4 out of 5 by 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. [This review was collected as part of a promotion.] June 30, 2016
Rated 4 out of 5 by 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. [This review was collected as part of a promotion.] June 29, 2016
Rated 2 out of 5 by 104 Octane boost Product provided some octane boost to eliminate knocks but not the same as higher octane fuel for performance or MPG. [This review was collected as part of a promotion.] June 29, 2016
Rated 4 out of 5 by 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! [This review was collected as part of a promotion.] June 27, 2016
Rated 4 out of 5 by great product added boost to my warmed over 57 283ci Chevrolet, just what it needed to bring out the best in her. will be adding this with every tank. [This review was collected as part of a promotion.] June 27, 2016
Rated 4 out of 5 by Works great Works well on older cars and V8's that aren't so computer controlled. [This review was collected as part of a promotion.] June 27, 2016
Rated 1 out of 5 by No noticeable difference I've useen this product before and still saw no noticeable difference. [This review was collected as part of a promotion.] June 26, 2016
Rated 4 out of 5 by Easy to use Put it in older four stroke dirt bikes and a truck, seems to have made a big improvement. Looking for more! [This review was collected as part of a promotion.] June 25, 2016
Rated 5 out of 5 by 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. [This review was collected as part of a promotion.] June 25, 2016
Rated 5 out of 5 by Really Works! I tried this product and noticed changes right away. Better power and running smoother! Even better gas mileagetoo. [This review was collected as part of a promotion.] June 24, 2016
Rated 4 out of 5 by 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. [This review was collected as part of a promotion.] June 24, 2016
Rated 4 out of 5 by 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. [This review was collected as part of a promotion.] June 24, 2016
Rated 5 out of 5 by Worked just as adverticed This is a great product and should get more adds on TV and magazines! [This review was collected as part of a promotion.] June 24, 2016
Rated 3 out of 5 by Great Expectations I obtained this product couple days ago and put it to use immediately. Sorry to say did not notice much improvement over running regular premium gas. [This review was collected as part of a promotion.] June 24, 2016
Rated 1 out of 5 by 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. [This review was collected as part of a promotion.] June 24, 2016
Rated 5 out of 5 by just the boost my car needed the extra octane made the car run smoother and took the knock out with the cheaper gas [This review was collected as part of a promotion.] June 24, 2016
