Caution: The use of a synthetic base oil does not justify extended lubricating oil change intervals. Extended lubricating oil change intervals can decrease engine life due to factors such as; corrosion deposits and wear. Special “break in” engine lubricating oils are not recommended for new or rebuilt Cummins engines.
Use the same type lubricating oil during the “break in” as that which is used in normal operation. Caution: A sulfated ash limit of 1.85%has been placed on all engine lubricating oils recommended for use in Cummins engines. Higher ash lubricating oils may cause valve and/or piston damage and lead to excessive lubricating oil consumption. For natural gas engines, a sulfated ash range of. 03 to. 85 mass percent is recommended. Cummins Engine Company, Inc , does not recommend the use of ashless lubricating oils for natural gas engines.
