Rated 4.7 out of 5 by 48 reviewers.
Rated 5 out of 5 by Made my '69 Merc Purr like a kitten I've been using additives & higher octane fuels in my '69 Mercury Marauder 429 for a long time to obviously help compensate for the lack of leaded fuel. The tank of fuel I used with this octane boost seemed par for course at first, certainly ran at least the same, but as I went through the tank the idle seemed a bit smoother and the valves seemed just a bit quieter. Might have been just me, but regardless, I'd rather add this than some of the other additives, both on price, contents of the additives and convenience of availability. Have to wait & see long-term. Overall happy for now! [This review was collected as part of a promotion.] September 19, 2016
Rated 5 out of 5 by Amazing A friend of mine told me about it and told me it was great. I must say it made a big difference in my truck performance. September 8, 2016
Rated 5 out of 5 by works great! I have several performance cars and have a hard time finding good gas. Took care of the pinging by adding this product. [This review was collected as part of a promotion.] August 19, 2016
Rated 5 out of 5 by Noticeable difference Gave me much better acceleration and power right after using. Gas mileage was better too. Will be purchasing this product again. [This review was collected as part of a promotion.] August 16, 2016

Rated 4 out of 5 by It Makes A Difference Added 104 Octane Boost to my late model truck. The engine seemed more responsive and my fuel economy was slightly better than the previous tank of fuel without the additive. I plan to purchase 104 Octane Boost and add it to a another full tank of fuel and see if the results are similar. [This review was collected as part of a promotion.] July 7, 2016
Rated 5 out of 5 by Worked Excellent, as advertised I received this product and tried it out immediately, I have a high performance engine and noticed the difference right away, I will purchase this product for all my vehicles in the future [This review was collected as part of a promotion.] July 5, 2016
Rated 5 out of 5 by Does what it clams! I got this for my older mustang I own. It's not daily driven and is just used as a pleasure car. With it being a 96 also I figured it was time to run some fuel system cleaner through it again. This has always been my go-to product. It does what it says it will do, and it does it very well! After running a tank of gas with this in it the car is running great again. Start ups are quicker and all the power of the 4 valve enging is back!
