Oil Drain Intervals for Diesel Engine
s
Engine oil drain intervals depend on the engine-oil quality, its conditioning, the operating conditions and the fuel used.
The intervals quoted (Table 3) are guidelines based on operational experience and are valid
for applic
ations with a standard load profile.

= To be used in conjunction with fuels with max. 500 mg/kg sulfur content.
The oil drain intervals in the table are recommended guidelines when using diesel fuels with < 0.5%
sulfur content. The limit values specified in Table 4 for used oil must be complied with. The numbers of
operating hours quoted for oils must be confirmed by means of oil analysis.
The oil drain intervals must be determined by oil analysis if one or more of the following
difficult operating conditions are encountered:
• Extreme climatic conditions
• High engine start-up frequency
• Frequent and prolonged idling or low-load operation
• High sulfur content in the fuel of 0.5 to 1.5% by weight (→ Page 10)
New oils must be selected w hich have t otal base numbers appropriate to the sulfur
content of the fuel in use. (→ Page 08)
