1.11.2 Lubricant specification
Use oil that meets at least the following specifications:
Global Specification: DHD-1
ACEA Specification: E7-04, E3-96, E5-02,E4-07 or E6-04
API-Specification: CG-4, CH-4, CI-4, CI-4 Plus, or CJ-4
Since the viscosity (viscosity) of lubricating oil changes with the temperature, the am-
bient temperature at the motor operation site should be selected based on viscosity
grade (SAE class). Optimal operating conditions are achieved if you follow the oil vis-
cosity graph below.
Occasionally, temperatures below the limit can compromise cold-start capability, but
not lead to motor damage. Operating limits should not be exceeded in terms of wear
and tear reduction over a longer period.
Synthetic lubricating oils offer advantages because of their better temperature and
oxidation stability.

CAUTION
Avoid mixing different brands of oils. Different
brands of oils are not usually compatible with
each other and if you mix them, this can lead to
seizure of the piston ring and cylinder as well as
wear and tear of the moving parts. It is best to
always use the same brand and type of oil with
subsequent maintenance.
NOTE

The intervals between two oil changes
depend on the fuel properties. Be sure
to use only the recommended fuels.

For analysis according to the Perchloric
acid method, the limit for the total base
number amounts to half of the corre-
sponding value for new oil.
