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

Good quality cleaning for the injectors engine

It's a no brainer to use this. Keeps my IPs & nozzles clean (visual inspection compared with other brands).

Have used this in my 2001 F350 7.3 L and it keeps the injectors clean. Also use "All in one" diesel additive because of the Ultra Low Sulphur fuel is not good for older diesel engines.

So far so good. Seems to have increased my power on my engine a bit. After the 2nd bottle we'll see for sure.

Try in in my ford F350 and it started running better then before. got better fuel mileage and ran smoother then before. It is also running quitter then before.

Engines runs smooth never any hiccups, good mpg. Put in every fill up. I have 254,000 on a Chevrolet 2500 HD Diesel. It works.

Used in every Diesel I have owned , So far never had to repair any injection pump or injectors .You get what you pay for, Quality Product

Good product. I will continue to use this product

We have lived in many, many climates and I have used DIESEL INJECTOR CLEAN as well as many other AMSOIL products since the truck was purchased in 2002. I have found that the Injector Clean has worked extremely well for me and I will continue its use.

Put 3 bottles in one 100 gallon tank on an International mv with a cummins and got .2 mpg better on that one fill.

This oil does what it says it does and more. Truck has 164000 miles and it runs smooth

Iv'e been using this product in my 1997 ford f-350, 7.3 power stroke for some time now. So far so good, engine is running great.

Great product !!! In few, words, I use only Amsoil for my truck..: engine and differential oil ( synthetic for both) and also the Amsoil coolant. Besides, the diesel additives ( from Amsoil). So...Amsoil all the way !!!!!
