Oil change intervals can vary depending on oil grade
and sulphur content of the fuel, please refer to Tech-
nical Data page 113.
Oil change intervals must never exceed a period of 12
months.
If you want longer oil change intervals than given in the
table Technical Data page 113, the condition of the
oil must be checked by the oil manufacturers through
regular oil testing.
Oil level, checking and topping up
The oil level must be within the marked area on the oil
dipstick and must be checked daily before the first
start.
Check the oil level a while after the engine has been
switched off. The oil in the engine needs some time to
return to the sump before a correct oil level check can
be performed.
Wait 15 minutes if the engine has been run at normal
operating temperature. Wait an hour if the engine has
been idling.
The oil level shall be between the MAX and MIN marks
on the dipstick. Levels that are higher or lower than
these marks can damage the engine.
IMPORTANT!
Do not fill over the limit for max. oil level. Use only oil
of the recommended grade, refer to Technical
Data page 113.
1 Fill the oil slowly via the filling hole on the top of the
engine.
2 Wait 5 minutes to allow the oil time to reach the
sump before checking the level again.
3 Then check the level again.
NOTICE! The volume between MAX and MIN is about
1.5 liter (0.4 US gal) for D4 and 3.5 liter (0.9 US gal)
for D6.
