5. Technical Maintenance for Fuel Lubrication
System
5.1 Selection of Lubricating Oil
Lubricating oil (engine oil, see Fig. 2-8-18) for the diesel
engine lubrication system should be selected upon the
ambient temperature.
Caution:
different grades of oil should not be mixed.
5.2 Measuring of the Oil Level
Engine oil is a consumable which ensures the diesel
engine to operate formally, therefore, the oil level should
be checked regularly. For example, check the oil level
when adding fuel or before a long journey.
The oil consumption depends on the driving condition,
weather and traveling condition. The oil consumption
rate may reach 1 L/1000 km, and the oil consumption
rate of the new diesel engine may be higher.
When checking the oil level, make sure that the diesel
engine has been preheated and the vehicle is parked on
a flat floor, stop the engine and wait for 3 minutes. Then
check the oil level.
Measure the oil level in the oil pan with the dipstick
mounted on the left side of diesel engine (see Fig.
2-8-19), draw out the dipstick and wipe away the oil on
the dipstick with a piece of cleaning cotton cloth, then
insert it into the oil pan till to its end, draw it out again to
check the oil level.
There are upper/lower scale marks on the dipstick to
help to check the oil level (see Fig. 2-8-20), the oil level
