Customer Ratings & Reviews

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.

I tend to be skeptical with products such as this but I must say I was pleasantly surprised with the results. While it is difficult to determine what exactly is happening inside the engine I have data that confirms an increase in MPG of about 8%, just as advertised. I plan to continue to use this product.

It has made a noticeable difference in the mileage of my 6.0 diesel

I use this additive in my 2016 Ram ecodiesel. It is a great value and I've had no issues with injectors.

I use in every other tank or every tank on long trips. Haven't had any issues and the truck runs great and smooth!

It seemed to improve the performance in my 1997 Ford F-350, 7.3 power stroke. If been using the injector cleaner with no issues. I Would like to see the boost/cleaner sold in OZ marked containers for more controlled application
