Use Pi in all my cars as well as my kids and grandkids when I do other servicing for them. Helps with keeping the fuel system healthy.

My 2019 silverado has done terrible with gas since I bought it. I recently added this fuel additive since the ones in the store never work. I'd say that I'll always use ams products it works. I can't complain with a few extra miles per gallon.

Wonderful product noticed an immediate improvement

This stuff works great,improved performance & mileage booster. It is incredible. Definitely use this product again

ChatGPT says this stuff is great. I put it in my vehicles every 5,000 miles.

For my Ford F53 gas motor coach, I use premium gas, but when traveling there are times that premium is not available. That’s when I use the Amsoil PI. I can feel a perceptible improvement with low end torque. I’d recommend buying a few extra to keep on hand when traveling!

I use the PI every 5000 miles in my 2018 Audi Q5, 2023 Honda Pilot and 2021 Mustang GT. There is a noticeable change in performance and mileage. Also the Feel of the vehicle engines always appear to be smoother. Highly recommend this product. Short money for big long term gains

CLEAN everything . Keep it new

I use this as recommended by amsoil. We have seen an improvement in my wifes 2024 Dodge Hornet GT. Fun car.

I cannot believe the improvement with the engine performance since using this great additive! I have a 2021 F150 with the 2.7l engine. With the A/C on the engine ran a little rough at idle. After driving some miles the engine ran very smoothly and quietly. I add a bottle as recommended every 4k miles. Try a couple bottles and you will notice the improvement in performance!

I recently purchased a 2005 pickup truck that ran a little rough. I decided to get a case of AMSOIL P.I. Gasoline Additive, hoping to see some improvement after a few tanksful. Well, the improvement was VERY noticeable right away. I'm going to continue using this!

I usually run premium in my truck, but those times I don't, I add this additive. You would never notice the difference between grades.

I have been using this cleaner for 2 years now and I can see and feel the difference.

More power better gas mileage engine runs cooler.

My truck runs great…but after adding a bottle to a full tank, it runs even smoother and you can’t even feel it running at an idle. I have added it to the tank on a couple of small engines that had surging idle issues. On one engine it fixed the surging and the other one it improved it.

This is a great preventative cleaner. Works as should and can feel the power come back.

I have been using other brand name fuel additives for several years in my 2003 Explorer and 1999 Lexus. I figured they were doing the job but never noticed any change in fuel economy, acceleration, or smoothness in engine performance. During and after one tank using AMSOIL P.i. I noticed ALL three!!! I am surprised and very happy with this product. I will use it every 4K miles in both vehicles.

I add a bottle every oil change (5000 miles). Switched from Sea Foam. Not only is Amsoil cheaper, my truck runs noticable better.

engine sounds and runs good

I use a Bottle of this at every oil change.
