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

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

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
