3.2.1. Engine oil
Engine oil is specied by its performance and viscosity classica-
tions.
Performance classication according to
API (AMERICAN PETROLEUM INSTITUTE)
CCMC (COMMITE of COMMON MARKET AUTOMOBILE CON-
STRUCTORS).
ACEA (ASSOTIATION DES CONSTRUCTEURS EUROPÉENS DE AU-
TOMOBILE)
Viscosity classication
To determine SAE (Society of Automotive Engineers) viscosity
class, the ambient temperature and type of operation in place
of usage of the machine are decisive.
Permitted oil according to API: CH-4/SJ; CI-4/SK
All season - SAE 15W-40 (e.g. Valvoline, Premium Blue,).
NOTE
Exceeding of the lower temperature limit does not damage the
engine, it may only cause starting problems.
It is suitable to use general-purpose multi-grade oil in order that
oil need not be exchanged because of ambient temperature
changes.
Use of synthetic engine oils is permited subjekt to the same per-
formance and viskosity limitations of minarel (petroleum) based
engine oils. The same oil change intervals must be applied to
the synthetic oils that are applied to mineral (petroleum)based
engine oils.
For easier start at temperatures below 0 °C (32 °F), SAE 10W-30
oil is recommended by the engine manufacturer.
Exceeding the upper temperature limit
must not last for long, taking into con-
sideration reduced lubricating proper-
ties of oil.
When using oil according to API CG-4/
SH, the exchange interval should be cut
to one half, i.e. 250 hours or 3 months.

! CAUTION !
Oil for the ACE drum vibrator: SAE 10W-40;
API CI-4.
