If the fuel found in the vehicle has an American Petroleum Institute specific gravity reading of 39 - 44, and the fuel sample you used for comparison has an American Petroleum Institute specific gravity reading of 30 - 39, drain the fuel system and refill with a known good diesel fuel and retest.

A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
