I use this in my 17 Chevy Colorado Diesel and it works well to smooth the engine with better performance. I use the minimum of 2 ounces to boost the octane 3 pts and I cannot believe how much better the engine sounds and runs

I travel full time pulling a 41 ft Montana 5th wheel with my 2014 Ram 3500, so fuel economy is very important. Depending where in the country I am, I have seen as much as an additional 3 mpg using the octane boost

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.

It really works, I add it every time I fuel! Truck gets more power pulling heavy loads and better mpg. I add full 64oz bottle to my 400 gallon fuel tanks

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.
Reviewed by Jacob:
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 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.

It works the same as all of the competitors but is twice the price. As an o/o price means everything.

I bought my 2012 Ford F350 used with 80,000 miles and this is the first Diesel vehicle I have personally purchased. However it is not my only experience with Diesel trucks. For 20 years I used diesel trucks Light and Medium Duty as part of my job with the Federal Department of Justice communications division. The vehicles that we were able to personally service due to them being on remote work sites we were able to make last much longer, and they were far more dependable. I believe this was because we only used Amsoil fluids in them. Yes all the various products that Amsoil manufactures for them. We were even able to make the inadequate Ford 6.4 turbo diesel last in 3 vehicles when we found out the biggest problem with them was that the coolant degrading led to turbo charger and major engine failure the majority of the time. When comparing the available coolant products I found that Amsoil had developed a specific formula for diesel powered vehicles we purchased it. It extended the turbo life and prevented the documented damage due to coolant deterioration. Your automatic transmission fluid was the same as well, I believe it extends the life of the transmission as a result of it specific engineered formula. I only use the signature series products as I use my trucks to do a significant amount of towing and hauling. I have utility, and stock trailers, as well as a large 5th wheel RV that is towed frequently with my current 2012 Ford. I also find the long life of the oil filters are a great asset as well. I know using Amsoil products have increased the life of the vehicles I have used in the past and am confident that it is going to increase the life of the one that I now own. Also I now have converted all my other gas powered vehicles to Amsoil products as well and I am very happy with that performance as well.

This was my first time using this product from AMSOIL, but I definitely will continue to use it going forward as it has helped tremendously overall with my trucks all around operation in regards to it's fuel system.

Reviewed by Resolute:
Ford recommends No.1 diesel (47 Cetane) for their diesel lineup. That fuel is not available in most southern states and considerably more expensive where it can be found. Bio-diesel is showing up more often, sometimes as your only choice for fuel. My F250 with the 6.4 liter diesel suffers both in performance and economy burning 40 Cetane or bio-diesel. I've used off-the-shelf Cetane boosts with moderate success, but since using Amsoil Cetane Boost, my engine run smoother, quieter, and delivers a near 20% increase in fuel economy. To date (and miles), I have not suffered the fuel delivery woes so many other Ford diesel owners have suffered. Is it due to utilizing Amsoil products? Most likely.
