This is one of the only products on the market that really works, my APR guys recommend it. My 2022 ALLROAD A6 is tuned to 93 octane even though 92 at the pump, 93 gives my 401hp & 517 torque with 3.0T. I use 1/2 a bottle. My other car is a stage II 2016 RS7 which i also have turned up to 93 octane, churning out a blistering 730 hp & 797 TQ with upgraded air box 4.0T. THIS POTION GENERATES REAL MOTION. 1/2 a bottle mixed into 92 at the pump generates around 94 octane in my tank (guessing) when poured directly in the tank. A extreme noticeable upgrade in performance. Read more

Obviously I have not used 12 quarts of octane boosters yet from the dozen I purchased, but I have been using Lucas octane booster in two old classic cars for years. With a tank of gasoline, one bottle may not get my octane to 93 as was recommended firvthose older engines in 1958 & 1964 cars, but it increases my 89 octane gas to at least 91 which help make my engines more efficient.

The Lucas Oil Octane Booster is a game-changer! It noticeably improves engine performance, reduces knocking, and enhances fuel efficiency. Easy to use—just pour into the tank. Works great in both cars and motorcycles. A must-have for anyone wanting better combustion and smoother rides. Highly recommend this 12-pack for regular use. Five stars! Read more

Great for long trips or when you want to maximize engine performance. Read more

Owning a few classic cars and living in California, this product is a must for me. Even on a finely tuned engine running supreme Techron, I would still sometimes get a minor ping going up steep hills. Especially on hot days. Air cooled engines run especially hot and can ping under load more than their water cooled counterparts. I tried running a few different octane boosters, but nothing comes close to this Lucas booster. It probably improves the mileage too, but I don't really pay attention to that with the old cars. Even at $10 a bottle, it's cheaper than repairing a dropped valve seat. I buy it by the case and keep a bottle in the trunk. Read more

I started using Octane boost as my engineeer brother-in-law said he uses this one and it will keep your engine/piston clean and carbon build-up free. I honestly don't know if it is working, but I respect his opinion and my cars engine perforrmance seems to be boosted as a result. As I believe in impeccably maintaining my vehicle so it lasts a very long time, I'm using this product. My car is 13 years old and dealerships have said how clean and new and well-maintained my vehicle is. Read more
