Great gas treatment the best I’ve ever used

if there is a product I trust, I use it, and here is one of them

This stuff works wonderfully. My gas mileage went 3 miles per gallon

This product works much better than other off the shelf products. You might even notice a slight drop in performance during the fuel tank that the product is cycled through. Wow what a difference in the following tank! It's like your injectors were plugged or your fuel pump wasn't working well.

I have heard about your products while I have been using chevron products which I never saw a difference but when I use yours ga additive I felt the difference right away on my jeep gladiator no more shaking or hesitation on acceleration thank you

I used it to clean my fuel line! It works great!

Love your oil it’s nice to no you don’t have to worry about it when I use your oil

I'm not a scientist, so I can't provide anyone with specifics. It seems to do a good job of keeping the engine internals clean. I use it at every oil change on my wife's car.

Great additive every once in a while

Put this in an empty tank then filled up and got easily 3 mpg more on the highway than usual. Great stuff 2018 Silverado 1500 4x4

Works as advertised. Notice the difference right away at my first oil change at 13,000 miles / 10% oil life on Monitoring system. Bought my charger at 4,000 miles. Twice before every oil change seems to do the job. I only use it as recommended per instructions.

Everything that occurred in your video happened with my 2003 Ford Explorer Sport (301k miles) after one tankful of gas. Increased acceleration, smoother idling and increased MPG. I am extremely pleased with the results of the Amsoil P.I. especially after using many competitor's products with no results. Great job, Amsoil!!

PI seems to work cleaning the injectors.

Been using this product for more years than I can remember, yeah I'm old! Keep up the good work Amsoil!

Not that gas is bad as it use to be in the day but, it's still not perfect for todays injectors which clog way to easy. I've used this in honda's and ram's ..... I did notice improvement.

The Amsoil P i. Increases power and overall performance in my Husqvarna Kohler 20HP tractor. Also keeps the carburetor and intake cleaner.

Noticed my engine started running like it should after using 👍👍

This thing works magic, stop waiting and test it today!

Good product. I use every oil change. Highly recommend. Well worth the money

I decided to try this on my 2016 Camry. After the road trip, it went from 393 miles till empty to 428 miles till empty. It obviously cleaned something out. I’ll keep my eye on the “miles to empty” to see how long it lasts.
