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.

This product does exactly like it claims.

J looked your product up & they say you use the best ingredients to keep vehicles running smoothly & I want to keep my car running great

I can almost instantly feel the increased horsepower and over three tanks of gas. I can notice the increased gas mileage.

Used in my 2020 Cadillac XT6 for a hot start shutter. I used one bottle in a full tank of fuel and the issue has been resolved.

I love the way my truck performs after use this product.

Every oil change, every 5000 mi. Feel the difference

it does, one treatment made a big difference in my fuel mileage, the increase showed up on the tank after the treatment. But, it brought the fuel mileage back to what it had been several months prior. I buy good gas but the injectors still need cleaning. I will buy this again

This product works great. It is awesome. I use it all the time with great results.

I believe this product cleans injectors the best of anything I've tried before. I always recommend this to friends and family

Works great

Use this in both our vehicles every oil 5k oil change with Chevron top tier fuel. Keeps fuel system clean.

Amsoil's product offering is extensive because they understand that different applications require different solutions. I run PI in my wife's 2024 Telluride (which does A LOT of idling), my 2019 F250 and my 2023 Street Glide (burning off all those EPA-mandated crankcase nasties). The results are not immediate, but I've seen an reduction of carbon deposits on the tops of pistons and valve stems. One bottle ever third full tank on the cars, and a third of a bottle every third tank on my SG.

I put it in and o noticed the tank lasted me longer.definitely saw the difference in my truck
