I use the product whenever my vehicle seems unresponsive. It helps

Every time I use this product my fuel mileage skyrockets. I tend to get an extra 20-40miles out of a full tank of gas. I daily drive a turbo car that produces a lot of carbon build up and I know this product helps keep the combustion area clean along with proper oil from amsoil. I would buy this product again!

My wife has a 2011 Ford Explorer and runs amazing as I use Amsoil from the transmission to the motor oil. I had an intermittent problem which I thought was a bad coil. It was only an issue when I would jump on it under hard acceleration, it would surge and buck really bad. I replaced the front three coils as that with my Bluetooth scanner told me and the problem was still there. I than determined it had to be an injector issue. I've tried numerous other products to hopefully dislodge whatever was clogged in the injector with no luck. Than I tried Amsoil PI injector cleaner and man what a difference. It runs amazing and every time I have to accelerate hard to pass someone or merge onto the highway no surging or hesitation. I was an Amsoil believer before now i use everything they have to offer and tell everyone I know about their amazing products.

It didn't work as good as I thought it would but I'm going to give it another shot and see how it goes other people had better experiences with it than I did

I have noticed an improved performance difference when using Amsoil P.I. Improver when used as directed through the years in the 2005 Ford Ranger. Highly recommended to anyone using 4 cycle gasoline engines.

I added to the fuel and make my engine run smothered and more efficient.

I generally don't believe in most of the injector cleaners on the market but every vehicle that I put Amsoil P.i. in shows noticeable performance and fuel economy gains and not for only one tank full but for several months following the application.

I used this in a 2012 Mustang V6 convertible that had an occasional miss. After using the motor smoothed out and the miss has gone away. I converted all my vehicles to Amsoil, motor oil, trans, diff, transfer case, rear ends and couldn't be happier. Quality products that due what their designed to do.

I plan to keep my Genesis for a long time and therefore I did diligent research and I couldn't find any other oil that met my standards of what a quality oil should be like and frankly, I didn't find any other that filled the bill quite as Amsoil.

We take a 500 mile round trip three to four times a year. I always use this at the beginning of the trip as insurance against fuel and injector problems in my 95' f-150 four by four. Have never had a fuel or injector problem! Winter weather here in Wyoming can be more than interesting and you DO NOT want problems out on the road! Highly recommended.I use this in all my fuel tanks, two and four stroke.

I feel for the money .. this product does an excellent job of keeping the fuel system clean

My gasoline vehicles run great and get better mileage.

Ever since I bought my truck, I religiously put Pi in at every 4000 miles. 65k miles later, my engine is still immaculately clean and with no lost power!

This product is great! Like every Amsoil product I have tried. I can't say enough about the quality of their products. If you value your vehicle, look no further.

Love how this cleans the fuel system and helps the engine run smoother.

I use this product with every oil change.

use these for my atv and my utv and my car and truck

Add to one tank of fuel and drive. Simple Enough. Strong and powerful enough that you see improvement in one treatment.

Good stuff does what it should
