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.
Bottom Line
Yes, I would recommend this to a friend.

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!
keeps ejectors clean and running smoother with better fuel mileage.
Bottom Line
Yes, I would recommend this to a friend.

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.
Bottom Line
Yes, I would recommend this to a friend.

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.
Bottom Line
Yes, I would recommend this to a friend.
