Great product works as advertised.

Could of been this with a combination of a amsoil oil, but my gas does in fact last longer, and everything is smoother

My vehicles run GREAT

I suppose it was fine Really no way to tell This is more of a oil-change maintenance item I add each 7000 miles

great product

Helps my 2000 Yukon with 320K miles run sharper, smarter and cleaner. My baby gets nothing but Amsoil products!!!!

Peace of mind with regular maintenance.

this product is excellent

I use this product in my 2015 Honda Pilot

I really like the out come of using this.

Every time I go to Mexico I buy 5 to 6 bottles I used 3 going to Mexico and 3 coming back. The performance of the truck when I go through 2 bottle I can tell the difference by alot because the truck start using less gas and I can fill more power.

Noticed gains the first time I used it. Easy to use, one bottle every 3-4k miles and piece of mind knocking my entire fuel system is maintained.

I add a bottle of this at every oil change (every 7500 miles). It makes my engine run smoother and it "feels" like it gets a bit more power. My CEL light was coming on and the code was for "knock sensors". I reset it with my code reader and it came back on within a day so. I reset it again and it would come on again. I happened to be changing my oil and added a bottle of PI to my gas tank around this same time. I reset it again and it stayed off. I was a bit confused, then I realized that the bottle of PI made my engine run so much smoother, that my knock sensors were not picking up any engine knock!! Now keep in mind this wasn't a permanent repair, I DID still end up replacing my knock sensors, but it was quite a few months later.

Phenomenal product! Cleans carbon out extremely fast and safe! Neighbors 20 year old arc would barely run. After 30 min after a dosed tank it started to run properly. 6 months later it is still running great!!

Use every 4,000 miles. I have had no problems since I started using PI.

If you want your engines to run smoothly then you should add this every 4000 miles, it works.

When used every 6 months it's like a tune up in a bottle. Great product.

Used it in my 1996 Ford Explorer with 185k miles. Used 2 bottles back to back tanks for initial clean up and now I'm getting 30-40 miles more per tank. Also smoothed out at idle. I was very impressed.

Used this on a 1992 4rumner to help with the injector cleaner up. After one tank of fuel the check engine light went out and hasn't come back on since. Also a smoother idle and better fuel mileage. I know there is no such thing as magic in a bottle. But I am pretty impressed with this product.
