I love it!

Works

Best inj cleaner hands down

I only recently became aware of this Amsoil fuel system additive through Rainman Ray. This cleaner produces great results. I definitely will buy again and again.

Slight improvements with idling and mpg's.

The amsoil gas treatment seems to work well. The only downside is the cost.

Tried this in both my 2015 Subaru Forester 2L Turbo and a 2016 Chev Silverado 5.3 L. After running a full tank through both I can say both engines ran smoother. The Subartu so much, I couldn't feel it at idle. Very impressed with how well it worked.

I use this in both vehicles and it does improve gas mileage for both like everything I have tried from Amsoil i love

I use this product regularly and keeps my engine running smooth .. seems to keep my fuel mileage consistent .. the engine idles great and throttle response is always quick .

My 2012 Toyota Camry LE was rough starting and not as responsive as it could've been. I poured a bit of AmsOil P. I. Into the tank and filled it up. Over the course of the week as I drove through that tank of fuel, I noticed the engine starting smoother and more quickly. The responsiveness was back too. P. I. Has always been a great product. It works well.

helps on all my toys

Had delay in throttle on my lexus is200t. Put this in and filled up. Then drove 30mins on turnpike at 85. When I got off I had just a little delay. But after the drive back it was gone. Also gained back lost fuel mileage from 26 to 28. Now 30 to 34. Have another bottle for my 2016 tundra when I service it. Lexus is port/direct combo injection. Tundra port injection. Just saying cause strictly direct may have different results. But do highly recommend even to my mechanic buddies.

Use it at every oil change. Combined with Signature Series 0W 20 gas mileage and performance have improved.

Seems to help run smoother and slight improvement in gas mileage.

Use this in all my vehicles. Works great.

I run this in our 2021 Lincoln after every oil change,works great.

Works as advertised

Have used this product for years on higher mileage vehicles to keep them operating without any fuel system issues. Especially in 2006 Tundra V8 that still runs like new.

I use every 4,000 miles.

The only product I'll ever use for all my small engines,it works great in them. Follow the directions and you'll see the difference very shortly. Let them sit overnight with the product if your engines have been sitting awhile.
