Started using P.I. Additive about two years ago because where I live in Missouri we use 10% enthanol in our gas and now because of the fuel prices last year it is now up to 15% so I like to make sure my cars fuel systems are treated every 6K mile. I just treated my 2014 F150 that is flex fuel capable and have notice my fuel mileage has picked up 1-2 MPG since the last treatment. I trust Amsoil products and am now using them exclusively in all my autos.
In my past 5 family vehicles in Upstate New York, this additive has helped them start esp in very cold snowy winters, while correcting some of the damage caused by Ethanol-Added gasoline. This is the only gasoline additive I use.
This additive replaces the Seafoam I used to use in my personal fleet to keep everything clean and well running, all very good as far as I am concerned.
I only ran this stuff one time so I honestly can’t say if it does what it claims but it seemed to work pretty well. I would have to run it at least a few more times and average my mpg to say for sure one way or the other.
Bottom Line
Yes, I would recommend this to a friend.

Helped to lower the exhaust tick I had. Less ticking sound from a 200004km 2.0 mivec engine.
