Oil For Diesel
While I am new to this Board, I am not new to diesel's.
Larry hit the nail on the head! Chevron Delo 400 is the only oil I would ever put into a diesel engine. Highly detergent and most importantly, withstands fuel dilution. I also prefer it in single grade vis a vis multi-grade. Check your own'rs manual or service dept. for oil weight recommendations for your area. I don't recommend it for hi revving gasoline engines because it's anti foaming capabilities at hi rev's are not as good as other oils, e.g., Castrol GTX, etc.
