Customer Ratings & Reviews

need to use more but seems like it works good

started using the 2mo ago noticed 1.5 fuel mileage increase plus better performance

I have been using this product for years, recommended by my mechanic, boosts mileage by 15-20% we highly recommend it

Definetly can tell a difference even on a small 722cc Kubota Diesel.

Really made a hudge differnce in response and power. Fuel milage went up as well, 2014 Chevy cruze diesel

This stuff really makes my 6.4L run great, more power, better has mileage and cleaner

I love the quick response on my orders

The length of the spout is useless. I have to pour the Amsoil into a Chevron bottle just to put it in my cars. Same with all your gas additives.

I use it in a 2012 deramax. It pulls daily about 15,000lbs or more. This product helps on everything.

Used on a long trip. Definitely made a difference!!

I really like this product!make's engine fire much quicker on start up

i CAN ACTUALLY FEEL A DIFFERENCE IN EXCELERATION THE FIRST TIME I USED CETANE BOOST.

Although Diesel Cetane Boost adds to my overall fuel costs, the added cost pays for itself in increased fuel mileage. Without the additive, my fuel costs are definitely higher. I also get increased power. So its a no brainer! better fuel mileage and more power for less money.

A diesel mechanic told me that I wasn't burning all of my fuel due to the lower cetane in standard fuel and that I needed a cetane booster. I now get a little better MPG and even a little better response from the throttle.

I have been using the Amsoil Since the 1970 Use the Product on the Farm In Kansas and now I left the Farm now so I well always use Amsoil it has save me on my Expenses for my Diesel Trucks and my Diesel Cars. Thankyou Amsoil for being here for us some 48 Years. Keep up the Good Work!

Increases hp of my truck, and great product for diesel engine.

Great stuff! I recommend it to everyone I know! Always noticed 2 to 3 mpg gain at every fill up. Great all-around throttle response, even when towing and plowing!

i put the recommended amounts in and run it every tank. I noticed when i didnt run it, i could tell the difference in how the motor ran/sounded

If you want results you need to be consistent in using the product. I like the fact that Cetane Boost is also cleaning injectors = you are killing two birds w/ one stone!

I put about 3 oz per 25 gal fill up. Ensures easier starts and better power. Diesel fuel is made like regular gas meeting minimum requirements with a Cetane number of 40. In comparison like the same power as 86 octane in Gasoline. Simply minimal.
