Customer Ratings & Reviews

This additive is amazing. Two bottles and my check engine light went out before I got out of the gas station parking lot. I would definitely recommend this product.

keeps my fuel system clean and performing great i use with every fill up thank for a great product

Great product but needs a bottle that doesn't drip all over the place when poured out

Runs great.

I think this product works great for my 2019 Ford F250 6.7 liter diesel truck. I've noticed a significant performance increase as well as mileage. I use all Amsoil products for my trucks as well as motorcycles. I'm glad I use them.

Definitely can tell the difference since I moved back to the Amsoil product versus other brick and mortar auto parts additives.

simply amazing!!

I've tried other additives like Lucas and Motorcraft for my 2018 6.7 Superduty. I've recently switched to Amsoil for my oil changes and decided to give Amsoil diesel injector cleane and cetane boost a shot. So far I have no complaints, with the reputation that Amsoil has you can't go wrong.

The Antigel is great too!

Works great in my 05 Duramax. Gets better mileage.

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.
