Rated 4.7 out of 5 by 43 reviewers.
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. 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 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! July 2, 2016
Rated 4 out of 5 by 104 Boost I normally use 91 or 93 octane in my BMW and after trying 104 Octane Boost, the car felt like it pulled a little quicker but not really that significantly. It might be more noticeable on a car that doesn't usually use higher octane fuel. July 2, 2016
Rated 5 out of 5 by Great Product Good way to clean your fuel system and boost the gasoline octane at the same time.Good for a tankful of gas. A little better performance in a bottle. July 1, 2016
Rated 5 out of 5 by Works good I put this octain booster in my '71 Lincoln with a high compression 460. It always knocked on pump gas with lead substitute but this product stopped the knock and it seems to run smoother and faster (better throttle response) with no need for additional lead substitute. July 1, 2016
Rated 4 out of 5 by Works well I tried the product about 2 weeks ago and it works well. The best part of this is that it works quickly to smooth a rough running engine. Thank you for a good product July 1, 2016
Rated 5 out of 5 by It makes a differance I have a 70 Superbee with a 383 big block this product seems to make it run smoother at higher RPMs i am going to try a couple more bottles July 1, 2016
