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.

In my chevy silverado 92

Good stuff does what it should

Used it in a 2015 Nissan Rogue. More powerful feel in the throttle and 2 mpg increase. I am very pleased with product!!

My nissan armada picked up 2mpg from two bottles of P.I. and a 1 full tank off fuel. Great product ill use every oil change( amsoil oil as well)

I was skeptical at first and decided to give it a try. I did notice a bump in power and fuel mileage. Now I use it at every oil change!

I use Amsoil PI in all three of my vehicles. My gas mileage and improved my performance improved now I don't have to mash on the gas to get the power out of my engine. I have tried many other products and I have found this to work the best.

I use it in everything including small engines and it reallyworks

Generally, I will use a system cleaner directly before an oil change to keep my fuel injection system happy and help eliminate any minor contamination. The truck I use this routine on has over 250,000 miles on it and doesn't miss a beat. After the treatment, I find the EFI meters fuel consistently delivering smooth acceleration all the way through the RPM range. I don't know about increased fuel mileage, but it makes the drivability of the truck seamless.

I always add a bottle to the tank when I am forced to get gas that isn't Top Tier.

PI is a great product brought my 96 mustang back to life

Works great

I use Amsoil products from oils and filters, transmission, grease, and coolant. This just seemed right to put in my vehicles.

Prior to additive I was getting 18 mpg city/hwy mixed... pretty regular trips and driving habits. After additive I started getting over 19, 19.7mpg.. using an ODB II Port gadget with app, Automatic Pro, and it does a great job giving you driving stats and trips taken, as long as you enter fuel fill ups and maintenance records, it does the rest. So, I'm impressed by the ability of this additive to clean my injectors and combustion chamber to give me better mileage and a bit more pep. I'm driving a 2012 Acura RL 3.7L V6.

I like it because I don't have to put it in every time I fill up my truck

I've tried techron before and didn't really know if it helped no but this one I felt it almost right away it does feel like it cleans.
