Run it every 6000KM - keep the DI injectors nice and clean!

First time user!! After my research I bought AMSOIL gasoline improved for my trucks. I’ve seen huge differences. I use a bottle every 5k when I do my oil changes with AMSOIL oil and filter. I’ve switched all my fluids over to AMSOIL in my trucks. You want the best of the best then buy AMSOIL!!!!

Just put the second bottle in tonight. To early to tell the results however, we will need to wait to see

Never used an injector Cleaner that actually works! That’s including the professional ones like 44K. Blows everything else out of the water.

I had not been using Top Tier gas for sometime and noticed my truck was not running smooth and mileage was down. I added one bottle of Amsoil PI at fill up and after just 1 treatment there was a significant treatment. Since then I have switched to Top Tier gas and add a bottle of Amsoil PI every 3000 miles what a difference!! My truck is a 2011 Toyota Tundra with 287,000 miles and I think I have added another 100k to its life....

One bottle added to a tank of gas seems to increase horsepower, but more importantly, cleans the engine and injectors. At some point (not sure of mileage at the time) they were replacing timing belt, serpentine belt, etc. and they suggested looking at the engine while doing the work. I said sure and when I picked up the truck afterwards they said they had a quick look and it appeared like new, so no work to be done. I attributed this to the PI Additive I had been using (as I had not used the upper cylinder lubricant up to that point.

Over all great products

Good stuff

It was a notch above all the rest on the reviews they don't go cheap on chemicals they give you the best

Good stuff

2019 F150 3.5l Ecoboost with 115,000 miles on it. Never ran a fuel additive through this truck until I tried this. Absolutely amazing. I ran two bottles through one 36 gallon fuel tank and the difference was stunning. Didn't think the truck ran poorly before, but the difference this PI made was unbelievable. Engine stopped having a rough idle, sounds way better, and improved efficiency. I highly recommend!

Worked great. Added to gas tank and let it do its stuff. Rough start went away.

Anytime one of my vehicles feels a little sluggish, I order PI because I know my car or motorcycle will run so much better. I've been using PI for years and can feel the difference it makes.

Product has never let me down. Always see improvements after using the product.

Gave it a smooth idle a nice pedal feel almost like the truck could breathe a little better

Works great started running this while ago ever so often in a full tank

I have experienced improvements in performance & fuel mileage.

Nice way to make sure my engines are operating at their best.

Unlike other additives, this one really makes a difference. Another running engine, little better gas mileage and more power.

Bought a bottle for my truck and my car. Not sure I'll buy this again, no noticeable difference in engine smoothness, performance, or fuel mileage. I'm not sure I'll spend the money on PI again
