Engine oil
The amount of oil your engine needs will
depend on a number of factors, including
driving style. Higher oil consumption can
occur when
the vehicle is new
the vehicle is driven frequently at
higher engine speeds
Engine oil consumption checks should only
be made after the vehicle break-in period.
Oil consumption of the SLR is slightly
higher than other vehicles. Please check
the engine oil level frequently.Checking the engine oil level
When checking the oil level,
the vehicle must be parked on level
ground
the engine must be at normal operating
temperature (min. 80°C)
Wait for at least 30 seconds with
engine still at idle.
Measure engine oil level with engine
still at idle.The oil dipstick and the cap are located on
the passenger side in the engine
compartment.
