Our 2020 RAM Limited was slowly becoming less fuel efficient. We were in the Mid teens for fuel mpg lately! A customer recommended your brand. So, I tried it last week and now my fuel economy has gone back up to the low 20 mpg range once more!

Seems to make my boat run better with less smoke.

Aids is helping keep diesel fuel system clean and in cold weather starts( below 20 degrees F)

I keep it handy in door cubby of my 2019 Sprinter 4x4 and use it on every fourth fill. Because I trust Amsoil, I believe this to be a positive contribution to my vehicles performance; but there is nothing direct tangible about this.

I really haven’t had a chance to really try it out because of work it I had originally purchased thinking that I was getting an injector cleaner. I will say everything that I’ve purchased from Amsoil has been above and beyond so I’m sure that this will be a good investment.

I have used this fuel additive since I purchased my truck new. Fuel mileage and power is not the reason I use it. I use this additive to reduce re-gen of the DPF and it works great. In comparison to friends with the same motor (6.6 Duramax) I rarely have re-gen. Great product at a great price from a trusted manufacturer. Very happy with my results.

Cetane booster ups the mileage on the Ram 3500 Cummins diesel by 15%. Gets 21mpg when not towing

Absolutely love this product. It works great and cleans the engine well. No smoke or after burning smells….

Works as advertised!

I use a combination of Cetane Boost and Diesel Injector/Lubricator additive. They are great products (and needed with the ULSD fuel and CP4 pumps). Every fill up gets an appropriate addition of these Amsoil products. I see an improvement in mileage with the cetane boost. I have yet to have any internal pump or injector issues, so I hope the cleaner/lubricator is also working. However...EVERY time I pour from these jugs, the runback and leaks are horrendous. C'mon AMSOIL, do better. I would love to have your execs have to pour some of this stuff out to see how bad of a mess the jugs create.

Used it once and have no opinion as to how it did with helping my engine. May use it more but not really sure.m I should have noticed better results.

I’ve used this for years in my 97 F350 7.3l power stroke. With a electrical fuel system, intercooler, upgraded injectors , this has provided the confidence the truck is getting the best considering how diesel fuel quality is going down.

Great product!

I add the cetane as I know the performance of the diesel engine is demanding. Don’t know if I really notice any difference, but I have always added it and my truck is 21 years old and does great.

Good product. Container could be better lid leakage if container tips over.

Cetane boost works well definitely feel a horsepower increase and acceleration and im using this in a M35A2 military truck along with the signature series diesel oil runs flawless great product

The Cetane boost really works. I see much better engine performance . I can see a big difference when I need all my horse power I can get from my diesel motors

My ‘98.5 Dodge Diesel runs so much better with a boosted fuel. I only boost it 3 points at a time, but I can seriously hear the engine smooth out and the power is much better!! I’m not a “Hot Rodder”, but I want my truck to MOVE when I put my foot into it……and it does!!!!

Awesome product raises cetane

Same as above.
