Customer Ratings & Reviews

I have not gotten to put this product( diesel injector clean) in service yet on my 2015 Ram 1500 Ecodiesel. The neck of the product bottle would not reach through the 2nd fuel filler flap so my much awaited product went out on the ground. Turns out a long funnel is needed to put this product into the fuel tank. Wish I’d known this before I wasted my first order of product. I expect good results once I can actually get it into my fuel tank.

As a long time Amsoil customer I knew that I could depend on Amsoil to get the job done. After installation of product I felt I had a bit more power and mileage even picked up a bit.

This product us awesome for my everyday driver. It keeps everything clean and in top performance. The order processing and shipping is the fastest I've ever seen.

I can easily notice a difference when I use this product. It works really good. I use it in my 2000 ford Excursion with the 7.3 powerstroke

Since converting over to all amsoil it to me just runs better and quieter. Very pleased so far.

Excellent Product. Increases my mileage and helps burn less diesel fluid. Increases my performance on my F250 6.7 liter diesel. Works for Me!!!

Use it with every fill up. Helps provide an easier start up during the winter months here in central NC and with the HEUI type fuel system.

Excellent ijector cleaner

I run this in my 3.0 Duramax. I've tracked every tank and now have over 15k on the truck. When this is added to the tank there is a slight mileage improvement, around 0.5 to 0.7 which tells me this is helping.

I use this product in multiple diesel engines on road and off road equipment. Cetane boost also as well for on road equipment.

Good product

The AMSOIL Diesel Injector Clean + Cetane Boost is amazing. It makes my 2021 RAM EcoDiesel purr like a kitten.

I have tried a lot of different products and this works the best for my 2021 Ram 2500

I've been putting this in my old diesel tractor and it likes a responds well to it. I recommend.

Awesome product 🎉

I used to use diesel clean but this stuff works a lot better

Like this product, truck starts much better and seems to run smoother.

With ULSD fuel not having the lubricity needed by the fuel pump, this adds much needed lubrication. It also helps to clean everything and improve combustion. I have seen about a 5% improvement in economy.

Used this product in my 2016 Ram 1500 ecodiesel while on vacation. Truck ran great, averaged 28 MPG highway!

I have been using this for a little over 2 years now as Maintenance and it works quite well. The injectors are quieter and with a slight inprovement in mileage, the cetane boost gives a bit more power with easy starts.
