They did a study in Japan on taxi card and wanted to know how they were getting 300,000 + miles out of there engines. It turns out they were adding something similar to Amsoil PI to the tank every 6000 miles which happened quit frequently due to being taxi cabs. So every 4000 miles is reasonable to me. I have only used this once and then bought a case. In my 2025 Subaru 2 4 liter horizontaly opposed turbo boxer I noticed an immediate improvement in torque and smoother running and acceleration. Again cheap insurance dirty injectors cause nightmares.

Absolutely the best top tier fuel additive that actually works. Smooth out rought idle,cleared my rich running check engine light. I don't feel my truck idling at stops. Worth the buy.

Awesome product I noticed a difference on my fuel mpg and performance

Read the product details and tried it on our vehicle within one tank of gas. Our vehicles are running so much better. This is our new go to and it saves so much money and you don’t have to go to a dealership to get your vehicle serviced I will continue to buy this product.

Performance Improver gasoline additive works very well! It helps keep fuel injectors clean!

Great product, love recommending it.

A great product for continued fuel performance

Loving it i can literally see the difference in driving after adding it to the car

Awesome product . Will continue to use

I bougth a case for 3 cars and hoping it works. Also I hope on my next purchase you guys have military discount. Thanks

Can definitely tell a difference from my idle after going through a few tanks of gas way smoother than before

Awesome

I used it in my Van and it seems to work better than not having it at all.

I use P.I. every 3 months on our vehicles just to help keep injectors running smoothly and clean. we have had no issues so it must be helping. its a small price for some added protection that can't hurt.

Great product

This product is a part of the maintenance regimen for my truck. After 75000 miles, my truck's power and gas mileage has remained consuistent.

Product really works. Purchase a 2020 chevy silverado 2 month ago very low miles runs good added the p.i. and I see the difference right away love it really works

I’m cautious about snake oil in a bottle. However, I’m very impressed with this. Started using it in Allis-Chalmers Antique Tractor, we pull with . Out of the hole, the engine is snappier . And in the light class, I’m able to pull a gear higher. Rarely power out. Just started using it in my ‘18 CT6 Cadillac. These are noted for a problematic 8 speed automatic. Not sure how it’s related, but it’s shifting smoother between gears. Not sure on the MPG improvement yet?

Part of my oil change regiment, when the oil gets changed this gets put in my gas tank. 100% trust any thing amsoil puts there name on !!

I have had excellent results with this product.
