Lubricant Selection in Regions Not Using ULSD

Engine oils specified in Table "Approved Detroit Fluids Specification" for the appropriate engine emissions certification and fuel sulfur level are preferred for all Detroit™ engines operating in regions not using Ultra-Low Sulfur Diesel (ULSD). If these lubricants are not available, lubricants meeting European ACEA E4 or E7 may be used at the specified oil drain intervals. Oils of lower performance may only be used at a 50% oil drain interval reduction, Oil Drain Intervals.
