Has anyone had any experience good or bad from using this oil in your Diesel Engine. I own a Dixie Chopper gasoline 27hp mower and the manufacturer recommends this oil in both the engine and hydros. It is a long drain truck oil designed for Diesel engines. It would simplify things for me if I started running this in all of my equipment. I use Bobcat brand hydro oil in my skidsteer and plan to continue.
