Added one bottle to 1992 Jeep wrangle that was idling rough, runs very smooth now, will be using in all my vehicles now.....

One or two bottles cleans clogged injectors and the fuel system and restores lost power. My cars and motorcycle run great.

I just toss one in every few thousand miles and it keeps me on the road. Happy customer!

Heard about this product from a comment on a ford explorer group that I'm in. I've been having a little issues with idling. A mechanic told me my injectors were possibly clogged and wanted to charge a lot of course. Gave this bottle a try and took a 4 hour drive to get this through the fuel system and it worked! My explorer doesn't idle bad anymore and it also fixed my fuel gauge lol before it would slowly go up when filling up the tank, now that needle just goes up fast. It's been 2weeks now and my explorer has been running way better since then. I've noticed better MPG as well. I used to run those chevron additives that Walmart sells , never again will I purchased those. I will only purchase AMSOIL additives for now on.

The engine doesn’t feel like it’s struggling. For some reason my gas lasted a lot longer.

Used this on my '86 Jeep Comanche P.U. (carburated) which has been idle for over 6 months. It smoked a little when fired-up at first but I'm convinced it stabilized fuel because it made the truck rum great.

Almost instant results.

Don't waste your time with the 99 cents gas treatments seen all over stores that are all really just snake oil in a bottle. The Amsoil P.I. gas treatment does exactly what it is sold to do. It improves today's high tech vehicles performance. P.I. keeps the entire fuel system clean. This means more mpg , less carbon build up , lest internal rust or build up that equals a more efficient running engine.

Chevy Impala with 3400 engine. 280,000 miles. I usually buy non-alcohol convenience store gas from Casey's. Not according to the label but, I regularly put in a maintenance dose of a few ounces of PI. I stay clear of the strong "solventy" fuel system additives because of all the plastic and rubber parts that make up my fuel system.

I've been a firm believer in the other similar product for many years. This stuff picked up where the other left off, amazing stuff.

I use this product with every oil change and my minivan has almost two hundred miles and the injectors are still as good as new and the minivan is still saving gas.

2006 Camaro V6 had firing issues and various engine codes had came up. After 1 treatment of PI Performance Improver followed up with 2 back to back treatments of the Amsoil Gasoline Additive upper cylinder lubricant the car now has no firing issues and no codes. I highly recommend the product at every oil change followed up with a couple treatments of the upper cylinder lube. For good measure keep the external fuel filter changed at every other oil change. All of this process I've completed as well in my 1999 K2500 with the old spider fuel injection on its 350 sbc. This stuff simply works.

Used as recommended for many years in both GDI & non-GDI vehicles for 200K+ miles. No issues with fuel injectors or Intake valve buildup.

Love it you really feel the difference

Your car feel thank you using this product!

Removes all the impurities from the gas.Vehicle runs smoother.

Great FI cleaner. Cleans combustion chambers and keeps your vehicle running new.

I use this in my 2013 2500 HD GMC and have had no fuel related problems in 160,000 miles.
