Performance I prover

I can not positively say that this has improved my octane rating, however the studies have shown that it will. I do believe it will not harm your engine, it could only improve the quality of fuel you use. I just can’t say if it “improved” my gasoline consumption. I do believe the detergents would help keep fuel cleaner.
I noticed an increase in gas mileage and a better response when I stepped on the gas right away. This product does what it says it will do.
Bottom Line
Yes, I would recommend this to a friend.

It Works

Hello, recently purchased some Amsoil PI performance improver and I'm very happy with the results of this product. I feel that it did a very good job in cleaning the fuel system and taking out any contaminants that were remaining in there. I noticed acceleration was better overall and very smooth shifting. I like how it is engineered to be used every 4,000 miles so it's not something you need to worry about putting in your tank every time you fill up. I would not hesitate to purchase this product again I feel it's a good buy and a good value.

Had a little hesitation in my wife’s van, put this stuff in it and it cleaned it right up. Picked up a few miles a gallon also. It will pay for it self
This is a great product, the long drain interval is awesome! I’ve been using amsoil stuff for over 20 years, and I couldn’t be happier! Thanks for great products!
I have only used this product 1 time so far. I did not notice much of a difference at first but by time I had used 1/2 tank of fuel I noticed my vehicle more responsive when I stepped on the accelerator and by time I had burnt 3/4 tank of fuel my mileage become notibily improved
Bottom Line
Yes, I would recommend this to a friend.

Run this in all of the vehicles. Never had any issues.
I used PI for the first time after an oil/filter change at 107k. I was amazed that I actually could feel the power and the fact that my gas mileage increased by 10%. This stuff really works.!!!
