I use this product all the time to ensure my fuel system is clean and lubricated. Works great!

Did the job. What else can I say.

had an injector sticking and used this product and within the second treatment it was corrected.

Great stuff, first time I have seen an additive make a deference in the way my truck idled. Smoothed it out.

After a $7,000 bill for replacing fuel injectors on my 2004 Duramax 2500 GMC, I started using AMSOIL Diesel Injector Cleaner. I have not had any more injector problems sense that time.

Seems to have given some more power, little more "pep" in the throttle.

I added injector clean to my work truck a 2018 ford transit diesel with 100 000 miles on it. What a difference! It runs very smooth now just like it did when it was new. Very impressed!

Running this in my 6.0 idles smoother starts easier

good to the last drop

I have been using this diesel injector cleaner since 2008. Diesel fuel is dirty; it's only marginally cleaner than marine bunker fuel. I use the Diesel Injector Cleaner every third tank of fuel; any longer, I can tell as engine performance and economy degrades. Whether or not you have a "Platinum" extended warranty on your diesel-powered vehicle, maybe you should consider using this product yourself.

Great cleaner for all components of injectors!

Good stuff

Works as they say increased fuel milage and smoother idle in my Duramax

I am the rare person who has the original fuel lift pump at 116,000 miles. I try to exclusively use Chevron from a busy station and use Amsoil Diesel Injector Clean at every fill up since the truck was bought new. No injector issues and no lift pump issues. I carry a spare lift pump just in case, but this stuff is the reason it has not been changed out.

Used two treatments, truck feels good

My truck had been neglected for years, to rich due not having filters changed regularly before I bought it, this has helped clean up my injectors and the rich smoke has stopped

I love the products from amsoil, best quality

The best diesel injector cleaner on the market, my 400hp engine is quite, non smoking, and runs efficiently (with no knocks) considering the fuel that’s being sold today!

Been using the 2oz for 5gal process for 2 tankfuls about 48 gallons. My mpg went up 2miles per gallon and my horsepower increased. Was having a low rail pressure code P0087 when towing so far I have not had the code since using Amsoil. The Amsoil was suggested to me by a dealership service manager, saying do this for 6 months instead of spending 3 grand on a high pressure pump. So far I have had very good luck with Amsoil. My 3/4 GMC has 170k miles on the engine. My hope is that Amsoil will buy me some more time. I am happy with the results.

Seems to work as expected
