Warning
Never exceed the MAX mark.
Warning
In engines equipped with timing variators it may
happen that a certain quantity of engine oil remains in
the cylinder heads when the engine is off and
requires a certain amount of time to flow completely
into the oil sump. This could lead to an incorrect
measurement of the oil level.
Recommendations concerning oil
It is recommended to use oil complying with the
following specifications:
- viscosity grade SAE 15W-50;
- standard API: SN;
- standard JASO: MA2.
SAE 15W-50 is an alphanumerical code identifying oil
class based on viscosity: two figures with a W
("winter") in-between; the first figure indicates oil
viscosity at low temperature; the second figure
indicates its viscosity at high temperature. API
362
(American standard) and JASO (Japanese standard)
standards specify oil characteristics.
