4 Specification of operating fluids
4.1 Engine oil
The engine oil is specied according to the performance and
viscosity classication.
Performance classication according to
API (AMERICAN PETROLEUM INSTITUTE)
ACEA (ASSOCIATION DES CONSTRUCTEURS EUROPÉENS
D'AUTOMOBILE)
Viscosity classication
To determine the SAE (Society of Automotive Engineers) viscos-
ity class, the ambient temperature and type of operation where
the machine is used are decisive.
Use of permissible oils according to API: CF
Use of permissible oils according to ACEA: E-3, E-4 and E-5
Year-round SAE 15W-40 (e.g. Valvoline, Premium Blue).
Note
Exceeding the lower temperature limit does not result in dam-
age to the engine; it can only cause some starting diculties.
It is recommended that universal multi-range oils are used to
avoid the necessity of oil changes due to changes of ambient
temperature.
It is possible to use synthetic engine oils if the performance and
viscosity classication of the oils corresponds to the recom-
mended mineral oils. The oil change periods must be observed
in the same intervals like when mineral oils are used.
For easier starting at the temperatures below 0°C (32°F), the
engine manufacturer recommends the SAE 10W-30 oil.
Considering the reduced lubricating capabilities of the
oil, the upper temperature limit must not be exceeded
for along period.
