I feel this product "did" clean my injectors.

Stuff amazing, cleaned the injectors on my old Datsun with one bottle. Improved my mileage on my Elantra considerably, highly recommend it

Nice to know that my fuel system is taken care of too when I service my vehicles.

After using this I notice i am getting 2 - 3 mpg per tank. So it cleaned something and will keep using twice a year. I highly recommend using this every 5,000 or 10,000 miles.

I put Amsoil in everything I have, from my cars , truck, motorcycles, dirt bike, Boat, side by side, ATV and yard equipment. They even sell gun oil!

I have used this product in both of our daily drivers. They idle smoother and the gas mileage got a little better in both vehicles as well.

been using this product since 2004. work well and will keep using it

I use this every time we make a trip to other states. I only need one for a tank. I got about 44MPG!!! at one point during my trip. I averaged 40Mpg there and back about 850 mile trip one-way. I'm still getting great gas mileage for close to a moth after putting it in one tank. I highly recommend this product!!!

I use PI every couple of tanks of gas and haven’t had any problems.

This stuff really works. It really cleans the fuel system.

Great product. I’ve used it every 5,000 miles on all my cars over the last 3 years.

This product helped attribute to fantastic idling and MPG just like the upper cylinder lubricant. I like to put this product in when I change my oil and go on a long road trip. The deep heat cycle of the engine helps clean the carbon deposits in conjunction with P.I. Improver. These products are fantastic and I will continue to buy them.

excellent product,outperforms gm oil

This is no snake oil like the rest of them on the market. This one works great at cleaning the injectors/pumps/combustion chamber etc. I saw my mpg go up 3 points after using this 3 times. From then on ive been averaging 29-31mpg constantly. Before it was 25-26mpg.

I would definitely recommend this product. I definitely felt the difference.

this is gonna be short and sweet. I love all of your products. just changed over to your diesel oil for my 2016 ram cummins.now I want to see if you guys carry fuel filters for it. thanks for the great products.

See the story in the previous product review.

Great product but bottle needs better functioning lid. Very difficult to remove

this stuff seems to make a difference, and its good to have a product you can trust

Great product!!!
