Seems to work well keeping the engine cleaner. Then again I try to only use Top Tier Gasoline in my car which also helps.

I have been using this product for over 4 years in multiple GDI engines and have never had a fuel injectors issue. Don’t skip this.

put it in and it works great

Works great better then other fuel additives

I use ever other oil change to help keep motor clean.

I use this with my all my vehicles. Great product and great price. Wish it was just a bit easier to get the white seal off the top of the bottle. Starting to feel the power return. Whoa.

I am an owner of a 2020 Ford Edge which has a direct injection system engine. Amsoil PI helps this engine run super smooth. I notice the difference when I forget to add it.

I have been using P.I. for many years, all I can say it works as described even better

This product actually works as advertised. My 2020 coyote f150 performs significantly better after using this product.

I use it 3 times a year in two vehicles 19 ford expedition and 23 ford f150. works as advertised

This product does exactly what it is advertised!!!!!!!!

I’ve been using this for the past year. No doubt it’s just as good as other products from AMSOIL.

You can feel the power

This is my go to at every oil change and midway to help with internal combustion carbon build up.

Excellent product

Tried this for the first time was really hoping that it worked for the price compared to others that I have used and wow was I surprised it really made a difference. I will continue to buy this product and keep using it and have recommended it to many other others.

Great gas treatment the best I’ve ever used

if there is a product I trust, I use it, and here is one of them

This stuff works wonderfully. My gas mileage went 3 miles per gallon

This product works much better than other off the shelf products. You might even notice a slight drop in performance during the fuel tank that the product is cycled through. Wow what a difference in the following tank! It's like your injectors were plugged or your fuel pump wasn't working well.
