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.

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
