I put a bottle in the tank at every oil change to help keep the fuel system clean.

I have never used a product for cleaning fuel injectors that actually increased my fuel mileage until I used this. This will be what I use from now on.

I initially used this pretty frequently for a while to clear out the fuel systems of my three cars. Now I use it at the recommended 4k miles interval. It is the kind of product that you won't see the good it is doing until you stop using it. Then you will notice a decrease in gas milage and power. I rely on it to keep my fuel clean, as well. My cars are 34, 22, and 14 years old respectively, so they need all the help they can get. This is good stuff!

Use P.I in all my machines, keeps fuel system clean, also keeps valve deposits to a minimum. Worth every penny.

I use this every winter when I winterize my car,motorcycle,side by sides,generator,chainsaws,lawn mowers,weed eaters etc. etc.and next spring everything is good to go..

PI is amazing stuff! I bought a 2014 F150 that had 61,000 miles on it. I had a hard time getting 17 mpg. After using PI for 8000 miles I now can get up to 20!

Engine loves it.

Put it in my car and get a average of three miles per gallon more then if I don't add it

So no way of tell on my personal vehicle of before and after use without scoping. But I would say it’s a good habit to use a good fuel treatment on occasion to help keep any carbon build up in check.

Use this every oil change to keep your fuel system perfectly clean. What I've done with 5 vehicles. No fuel related problems in 100k-165k mi.

Bottle came half open and spilled product all over my other merchandise that i Bought

It's a must for all D.I. engines even with a catch can. I use it about every couple of months seems to work for me. I also use it on my motorcycle, not the whole bottle just what it calls for and no problem. Sure it costs but it works and that's a small price.

Used it in my Toyota Highlander having 95,000 miles, it made a noticeable difference in the engine's idling making it idle smoother.

Been using this product in all my vehicles never had an issue with any injectors I've logged over 100,000 miles in four different vehicles with this product with never a problem

Have not been able to detect any improvement. Possibly changes are so minimal that it is hard to notice a change. I am not saying that the product is defective but might need some test equipment to pick up a low-lying improvement.

Getting 2 mpg in my wife’s car. It has an eco boost engine and can’t believe the difference this makes in mileage and performance

Great

More horsepower & better mileage after using Amsoil gas treatment.

Using this for several years on a 19 year old Honda Element with 152k, Definitely notice a bump in performance & gas mileage.

I’ve been using PI in my tanks for a long time I’ve pulled injectors out after 150k and using amsoil PI they look and work like brand new
