Customer Ratings & Reviews

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.

I drive a 2015 VW Golf Sportwagen TDI. Adding 2 oz of the Cetaine Boost at every fill up keeps my average mpg around 40 and close to 50 mpg at 75 mph on the interstate.

I use this at just about every fill up.

I trust and oil products they're made with high-quality materials and will continue to use them for as long as I own my vehicles the cetane boost for my diesel truck works as advertised. I will continue to be a loyal customer of Amsoil and would recommend this product and many other Amsoil products for purchase and you send your vehicles weather gas or diesel

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. I have noticed that fuel economy has improved also along with fuel conditioning and just in my honest opinion, this is an all around great product!

I use full strength when towing 16,000 lb fifthwheel.Always without trailer i use half strength.Truck runs so good with the amsoil additive.

Been using this product for 36 yrs.The product works excellent.

rgwea

want more power , then buy the boost believe me you will not be dissapointed

As advertised I have increased my mileage by 2miles per gallon.

Seems to work, more zip w/o tuner and stock equip. ( Calif )

It works well in conjunction with the other amsoil products

BEST I HAVE EVER USED TRUCK HAS MORE POWER !

I have a programmer in my 7.3, but the biggest kick I get is from Amsoil Cetane Boost. I pull a camp trailer and double a SxS trailer. Noticeable difference in power with Cetane additive.

I use it in my 09 f250 to keep it running top notch and boost my mpg. I use it as recommended and it works great!

When used as recommended my deisel started to experience predetination, I now use every 2-3 tanks rather than every tank, however there is no noticeable difference, for smaller deisel engines I recommend this as a 'once a year' type treatment to keep from excessive carbon buildup

In my 2004 F250 and my 2013 Allegro Breeze motorhome

Product seems to give a little bump in power and mileage.

It's works great. I keep it in my truck all the time. Especially when I'm towing.
