**** miles without having to change oil

I use this in my 2008 F 350 Super Duty Keeps my 6.4 Running Smoothly

use only rotella t6 in my ecodiesel. works great.

Not as easy to purchase as Amazon

It was exactly what i wanted while being cheaper then what auto stores were offering

This is a great oil for my Ecodiesel

Have used this product for many years in two (2) different vehicles.

Quality product reasonable price

I try to purchase this at Walmart every time we have to change the oil in the truck. Great Value.
