Customer Ratings & Reviews

This is the first fuel additive I've used that actually does what it says it will do. Used it in my GMC truck that had hesitation issues and it cleared up the hesitation and skipping after the first bottle.

Best gas additive bar none!

When I started using PI I immediately got better gas mileage and engine ran noticeably better. Have been using it ever since and will never stop.

It’s decent but would not say it’s any better or worse than say Techon

This product is awesome. I recognize a significant in throttle response with this Pi Performance.

Use this product in our 2017 Class-C motorhome, Ford E-450 super-duty V10. Runs strong!

Keeps fuel injectors clean.

Cleared up the cold hesitation my old f250 had.

I was a little skeptical about this product but after using it I’m a believer. My 2022 Odyssey had more power and I gained 1.5-2.0 miles per gallon. I will continue to use this for routine maintenance on my fuel system.

Love it

Did not notice a difference when used.

Well worth the investment

Great product, works well to keep your fuel system clean and your vehicle running smooth.

I installed a computer chip to turn off my gas cylinder deactivation system. My gas mileage should have dropped from the high 17s to high 16s. I put amsoil severe oil (80/90) in my rear differential and used PI gas treatment in my fuel. My gas mileage went to low 19s. Did my mileage go up because of the fuel additive or severe oil in my rear differential ?

Absolutely phenomenal engine and gas treatment.

Best fuel additive on the market!

Great product as I use it to keep my GDI gas motor clean of carbon deposits and running smoothly!

Makes vehicles run like they should and the mileage difference is worth it!

Never a hiccup.

This gasoline additive is way better than the other additives I have tried before. My engine is smoother and quieter. Worth the money!!
