    Diesel engines must use oil rated for diesel use. The latest rating is CI-4. Usually the diesel oils are rated for both with an "S" and "C" ratings, while gasoline oils usually only carry the "S" ratings. The "C" stands for compression ignition (diesel) and the "S" stands for spark ignition (gasoline). Look for the ratings in the little API circle or on the back of the bottles. A lot of people, including myself, like to use Shell Rotella T 15W-40 oil. It's designed for diesel engines, comes in handy 1 gallon containers, and is available at Wal-Mart.

    dunno what mark it is but i'm using an SA3 10W-30 oil due to the large temperature differences here. Last winter it was -20 degrees (centigrade) here. On the other hand, in the summer it can be up to +25 degrees (centigrade)
