Customer Ratings & Reviews

This is amazing, improved performance on all my vehicles. Improved my gas mileage.

Love the product, seems to work like it supposed to

This is my first time using this product so far everything is good. I hope it is cleaning my system out and I hope it increases my gas mileage. I will follow up and let everybody know what I have found out.

used to remove the emissions light, works great.

Use per instructions and keeps my cars injectors clean for over 75,000 miles.

Boosted the fuel economy on a 2010 tacoma with 396K on the ODO. Notable improvement in performance so will use again!

I use this gasoline improver in two of my cars and it always cleans up the combustion chambers very well. If it does that imagine how good your fuel injectors are gonna look like and perform.

All Iuse.

Works great!

I really see a difference!

Works longer than other products from other suppliers ..

I run this in all my cars every oil change and I’ve noticed in one that hadn’t had a cleaning in a while got a little bit better gas mileage

Had a car with misfire code. Wasn't ignition or mechanical. Fuel was old and varnished. Removed old fuel added fresh fuel and the Amsoil P.I. gasoline additive. After 20 minutes of idling reset the check engine light and have had no more misfires.Thanks David for recommendation.

This stuff just works! It delivers what ot promises. Believe it!

Put it into my 2020 Ford F-150 and noticed a slight improvement in both mileage and performance. I would recomend.

Definitely an improvement in acceleration and performance. Probably a small increase in mpg as well.

This turns 87 octane into 93 octane which means higher compression and better fuel mileage. If you can find non-ethanol gasoline, add one of these to your tank and fuel up with the non ethanol. AMAZING RESULTS! You’ll notice you can go quite a long way on that tank. You’ll also notice a little pep in your engine. This is super great for turbo engines!

I put this in my ole chevy and she seems to be running better and definitely idles smoother i would recommend to put in all older vehicles for sure.

was told needed new injectors after changing coils , still miss when first started until warmed up occasionally at red light. put 1 bottle of treatment and tank of premium with Amsoil octane booster ,been running great for 4 mo.

I have put this through a number of vehicles and noticed a difference in all of them
