Customer Ratings & Reviews

Before using the Cetane Boost I liked the power my rig was producing pulling our 32 foot RV. After the 2nd fill-up using it I could really see the difference especially when pulling hills. I now always have an extra 1/2 gallon on hand.

I have never gotten more than fourteen miles per gallon in my 2012 GMC Duramax Diesel. I put six ounces of booster in my tank and fifteen gallons of fuel. Fifteen point four miles per gallon. City driving. Only difference was the booster. That's twenty percent increase.

I buy it by the case and add with every fill up. Starts right up when cold, overall improved performance, notable difference. Great product that actually works!

I use this every other tank of fuel and my mileage is great and the power it helps add is great

Switched from the power services diesel clean To this product truck runs smoother and has more power highly recommend him goes in every time

Notice more power in every day duramax use . Also use in my kubota tractor. Frequency of regen is noticeably less. Kubota recommends 50 cetane this product gets pump diesel alot closer to cetane rating i should have. Will keep using thanks

Made my Cummins motor run smoothly and start easy

Great product gives an extra boost to my 04 Cummins

It sucks that we have to buy this type of stuff because of regulations. Didn’t think twice about where to go for an engendered quality product though.

Have 2004 Duramax , Amsoil product makes the injection system run better and quieter , so you know the product works , with less sulfur in today fuels , you need this protection

I will continue using this product
