Getting great fuel mileage

Wonderful

2016 f150. Truck runs smoother. Amsoil just make the best. All I can ask is that my truck keeps going, and Amsoil makes sure it does.

Been using this product for the last couple of years in intervals of every 5k to 7500 miles on my car and I always see small increase in fuel mileage and I can feel the engine run a little smoother after every bottle. Cheap way to maintain the engine.

Used this on a road trip at the first fill up and got even more mpg’s.

Helped clean the injectors and get better gas mileage.

First time using the PI Gas Additive in my 4Runner, which has 170k on it, I have used only one bottle and can tell a difference in fuel mileage. I’ll put another bottle in and see what hsppens. So far so good!

I added this to my last fill-up and noticed an extra 1.5 miles to the gallon over the previous tank. Reduced some clicking noises from the top end of the engine I noticed as well.

I've been using PI in all my vehicles for easily 7 years won't use anything else!

Cleaned up my injectors. This has improved my Subaru fuel mileage. We went from 22mpg average to 25!

I add a bottle once a year at oil change time

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.
