Makes the truck run great

Use in my duramax since the day I bought my truck

Use it in the summer, hasn't hurt anything yet.

Used to be close to a Costco fuel station with Top Tier diesel, both my JGC EcoDiesel, and Duramax ran great on that. Moved away and it's not practical to drive to that fill station any more. So I'm going BP diesel #2 with the Amsoil Cetane Booster and Injector Cleaner additive. So far so good, I noticed a difference between one fill up on the Duramax without the additive, and the next with it. Granted that was at the 2oz per 5 gallon concentration (+8 cetane), and now I'm at the 1oz per 5 gallon concentration (+4 cetane). Runs smoother with the additive, seems to burn cleaner too. I'll be using this moving forward unless I can find some premium diesel that has 50+ cetane but I haven't found any yet in the area.

I’ve run “the gambit” with diesel fuel additives- Amsoil’s diesel fuel additives are the best I’ve found. Why not use a product made by the same company that all of my lubricants are made by

Quality you can trust, additives that are a must for Diesel peeps!

I’ve used their injector clean for years with excellent results, engine now has 350k miles and running well. The cetane boost is a bonus and I can feel a boost in its performance.

Great Product. Increases mileage and power in my F250 6.7 liter engine. Been using it religiously for 5 years.

Very great product will use it every time thank you AMSOIL

Used with every fill up. I know that the fuel pump & injectors are getting the lubrication that is needed. And the cetane boost gives 19-22 mpg running empty, 11-13 pulling my 5th wheel

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.
