Customer Ratings & Reviews

I tried the AMSOIL Diesel Fuel Cleaner with Cetane Boost, and I could immediately tell the difference in performance. It works great! I put a bottle of it in every tank. I highly recommend this product.

help to keep the injector clean, lubricate my injection pump and wakes up the engine...

I have a 2006 Dodge Ram 2500 with a 5.9 Cummins engine. I bought the truck used with about 180,000 miles on it. As expected, there were things to fix and refresh so that I knew the true condition of the vehicle. I found that the engine did not start-up as easily as I expected, and it felt a little rough. On a whim, I ordered the injector clean + cetane boost when I was ordering oil, filters, and oil analysis kits. I figured that the injectors could use a little love. I poured the first dose into the tank after filling it and left it overnight. When I started the truck the next day, it was like somebody snuck in and swapped-out my motor. It started much more easily and ran much more smoothly. I will continue to use this product for as long as I drive a diesel truck.

With this, my diesel truck as a smokeless running

I normally research everything to death, and learned that Amsoil is at the top of the list for my needs. I drive a 6.7 Powerstroke, and this helps me avoid fuel system issues. Order and delivery is easy and fast. Thanks!

Product works great. I noticed a big difference in smoothness of idle and slight increase in MPG’s.

I used this on my last 2000 mile trip at off the beaten path fuel stops and it helped keep me running with good mileage numbers. Will use this more often!

I’ve been using this for several years and it’s to the point I will not fill up without having it in the fuel. I’ve had zero issues with anything fuel related. On my last inspection everything is spotless clean it’s how it should be I love the product

Engine hasn’t popped yet, this is not an energy drink for human consumption. It gets my engine purring almost as good as I get your mom going cleaning the pool.

I have been using the Diesel Injector Clean + Cetane Boost for several months now. My mileage has gone up about 23%. I feel my truck is running better too. I will keep using this on every fill.

It’s really help improve mileage

Works great for me and cleans the engine well….

En plus d'être plus prime, j'économise sur les régénérations ... Et j'ai la conscience tranquille pour la lubrification de la pompe à injection.

I use the product in 3.0 Porsche Cayenne turbo diesel, as soon as I start using it injectors noise drops, engine torque increases and mpg at 70/75 mph around 34/35 mpg with out it mpg same speed is at 30/31 mpg and torque drops, so I highly recommend this product

After applying the first dose to the truck it seems to have better power and better mpg.

Works as advertised!

I like other amsoil additives but this one works good too

Good product but dang, 20 gallons muh truck is 50 gallons murica size. Need 2.5 of the dang things.

Good Product, worth the price.

The injector cleaner is extending my fuel filter.
