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.

Seems to help performance in my vehicles, would recommend.

I have gotten better Gas mileage since using this product! Will buy again.

Car runs better and got 5mpg more !

A long time ago an Oil engineer to told me to use Amzoil 2 stroke oil, in my big Johnson outboard with low E gas. "Amzoil doesn't absorb water, so your cylinder walls won't gaul". My outboard keeps running. So, to me, Amzoil is the best. And anything they make is the best.

Have used every product imaginable over the years with little to no improvement in throttle response or gas mileage. I treated a full tank (16 gallons) in my 23 CT4 Blackwing twin turbo V6. She typically gets 19.2 city / 27.2 hwy (best ever on a 350-mile trip). Filled up again drove 520 miles there, 130 miles around town while there and 530 back at an average of 29.3 mpg an increase of 7.7% and a 5% increase around town since back! I'll keep track of how long the effects last.
