Maintenance

Oil change intervals can vary from 40 to 500 hours, depending on oil grade and sulfur content of the fuel. Note

that oil change intervals must never exceed a period of 12 months.

If you want longer oil change intervals than given in the table below, the condition of the oil must be checked by

the oil manufacturers through regular oil testing.

Lubrication system

NOTE! Mineral based oil, either fully or semi-synthetic, can be used on condition that it complies with the quality

requirements above.

NOTE! For 6 and 7-liter engines equipped with low profile type oil pans, the oil change interval must be halved.

If the sulfur content is > 1.0% by weight, use oil with TBN > 15

The engine oil must fullfil both requirements. For markets outside Europe, API: CG-4 and CH-4 can be used instead of

ACEA: E3.
