Customer Ratings & Reviews

I had just came back from a trip pulling an RV with my 2014 RAM 3500, 6.7 Ltr engine, and got (average) 9.8 miles per gallon of diesel fuel. Next trip, same route, same RV, and my 4500 mile round trip, upped the fuel mileage to 12.4 miles per gallon. Driving with no load in city and highway, my mileage is steady at 23. One longer trip on the freeway was at just under 29 MPG. Alas, now I've parked my truck as fuel costs are too high to take RV vacations.

I have used the diesel injector clean & cetane boost as well as all in one in the winter, both products work great, improve performance & fuel mileage. I also use Amsoil lubricants in just about everything we own, never disappointed. Great Products!

Add it at every fill-up

Great Product! I have enjoyed a 1-3 mpg increase depending on highway or city driving. Smoking has decreased when "Rolling Coal" , engine starts better in colder weather. Running a HEUI fuel system in a 6.0 and using Amsoil heavy duty 15W-40 I will get as much mileage as possible out the fuel system.

Used on my 2010 duramax gave smoother idle and quieted injectors down great maintenance item

I love the product but If I dont use the whole bottle I close it tight and it leaks--I cannot carry it inside my vehicle for the smell

Good cuality

Using in my Sprinter van. Works great and seems to improve fuel mpg. Will keep using it!

After one treatment the injectors are quieter and the engine feels smoother

SUPER PRODUCT. CAN TELL A BIG DIFFERENCE IN MY CLASS A MOTOR HOME. 300HP CUMMINGS, TWIN TURBO. 2006 ENGINE, 35,000 MILES. RUNS LIKE IT WAS NEW. CRUISE AT 75 MPH ALL DAY LONG. JUST HARD TO STOP A TRAIN!!

I truly believe in this product combined with 15/40 signature series oils. My Cummins dip stick stays supper clean at 15k mikes intervals. 100% legit

I use this product to maintain my fuel when I am out of state. U never know if u are pumping lower quality fuel. This helps maintain when I am not at regular fuel stations!!

I run diesel clean in my 1995 F350 powerstroke and I’ll see if I can run it in my 2022 Ram 3500 dually.

Seems to have plenty of power, fuel mileage has stayed the same or slight improvement. Idle is quieter

Works very good Like all Amsoil products

I can really tell a difference in how my truck runs after using this product

The weather dropped down in the low teens and the truck was a little rough starting

I use this injector clean once ever four tanks And I’ll use after I replace my fuel filter Every other oil change and I only use One gas company too Mobil for my diesel I will get 420 miles to a tank that’s with 35 inch tire never had a injector issue

Always keep my Duramax running well cleaning the injectors.

Quieter and smoother running diesel noise!!
