Customer Ratings & Reviews

I use Amsoil fuel injector cleaner with most fill ups. My truck has 139000 miles and still runs great.

THis product got rid of the black smoke bellowing out the exhaust and increase my miles to the gallon by 2 miles. The truck run FANTASTIC! Will buy more.

Works as promised

I use this at every fill up

Works great cleans injections

I've been using amsoil products for ten years or so and the proof is absolutely in the pudding you don't have to take my word or anybody else's just try it and you will judge for yourself five star service for a five star product thanks amsoil. I've been around diesels my entire 47 years.

We are currently on on 7500 mile trip out West and have added one ounce pure 5 gal. of diesel - towing a 5th wheel travel trailer. I run Amsoil 5w40 oil and a dual bypass oil filter system. Great products.

Great products from Amsoil . I have been using their products for years .

10 year old Duramax still going great.... always with AMSOIL

I try to use it every fill up my car runs very smooth and doesnt smoke as much. My 1991 mercedes 350sd gets much better mpg and hp. People are always asking if i did something to my car. Thank you

Love amsoil products they have always done my equipment and truck well would recommend to everyone

I think it's great

Use as instructed,it makes a positive improvement in performance

I feel that it has been working. I have great fast starts.

My Ram definitely runs smoother and starts faster and just performs better.

Very satisfied with products.

My Yanmar 420 hp Marine diesels ran 17 seasons, 2400 hrs and 38,000 miles with no service or repair to the fuel system other than filters. When we sold the boat the engines ran like new and passed the survey with flying colors. There is no better proof of a good product than this.

It is so helpful and we can tell the difference

I have used the Diesel injector cleaner on my 2005 Duramax with every fillup since I purchased it with 116,000 miles on it. I now 185,000 miles on it pulling a 35 ft Fifthwheel RV and have spent over 6 months pulling it over mountains and thru high plains they last three years. My injectors have yet to fail me and I attribute it to my use of this product. When I purchased the truck I changed all the engine and drive train fluids over to Amsoil. Nothing but the best for our Duramax.

Noticed Quicker throttle response and improved Horsepower with just one treatment Will continue using this product as directed (Yanmar diesel)
