Product recommended by my mechanic years ago, boosts the octane for over the road diesel fuel, Ram 3500 Cummins diesel averages around 20mpg

I've gained fuel mileage and performance , 2000 7.3 diesel 337,000 miles and going strong. I use all amsoil products on multiple pieces of equipment, cars,trucks, tractors, sleds,compressor, quads,bikes, the quality and performance has been unmatched for years .

Great stuff. Great price.

Already ran a bottle through my ‘98 Cummins 5.9L 24-valve at 3% and my truck ran great and strong!!! I’m just over 372,000 miles and it still purrs like a kitten!!! Runs and runs…….!!!!!

bien ajusté en quantité rend le moteur plus réactif....

I add this to every tank of fuel I put into my Diesel. I think its the best and most economical cetane boost on the market.

Noticed performance and power gain

I use this product every fuel up. Keeps my diesel running smoothly and reliably

I use this regularly. I have a 6.7L Ford which I use for both regular (non-towing) trips and also when I tow a 35 foot 5th wheel. I've compared my mileage when using this product and not using it in both scenarios. I can definitely see an improvement in mileage in both. Last time towing the 5 wheel up Baker grade, I was able to go up is 5th gear vs 4th; it added that much more power to the engine. I highly recommend it!!

Best stuff ever!

At todays diesel prices every little bit helps.

Yes it is a great product.I noticed the difference in acceleration the fist day I used it. I will order more . Fast delivery also.

The fuel system costs way too much to replace. This is worth the peace of mind.

I have always used a cetane boost. Amsoil makes a superior product. You need a good cetane additive to ensure your injectors get the lubrication they need. For an older diesel it’s a must

Better fuel mileage and power gain for my 7.3 diesel. Now that our leaders sell us the low grade fuels. I'm glad amsoil is still in the industry for the customers benefit. True performance company.

truck seems to run better when used

Just started using Cetane Boost, seems to give better fuel mileage.

I bought a new Silverado w/a 3.0 Duramax a few months ago. Being an advise Amsoil user I decided to purchase this product and try it. I definitely noticed a mileage increase and the engine seems a little stronger. It’s , as usual, another good Amsoil product!

I use this product and I have noticed a difference in fuel mileage and performance. It's worth the money.

Improved the mileage in our 36' class A motor home by a half mile per gallon.
