9.1 GENERAL

Oil pressure

Oil filter

Oil cooler

Oil consumption

Example:
Average measured fuel consumption: 30 litres / 
100 km = 300 litres / 1000 km
Maximum admissible engine oil consumption: 
0.3% x 300 = 0.9 litres / 1000 km
- Engine oil consumption = 0.9 litres / 1000 km is 
permitted
- Engine oil consumption > 0.9 litres / 1000 km; 
check the engine using the diagnostics table. See 
"Diagnosis".

9.2 TIGHTENING TORQUES

The tightening torques specified in this paragraph 
are different from the standard tightening torques 
cited in the overview of the standard tightening 
torques. The other threaded connections not 
specified must therefore be tightened to the 
torque cited in the overview of standard 
tightening torques.

When attachment bolts and nuts are replaced, it 
is important - unless stated otherwise - that these 
bolts and nuts are of exactly the same length and 
property class as those removed.
