TIP
To achieve the proper engine oil temperature for
an accurate oil level reading, the engine must have
first completely cooled down, and then warmed
up again for several minutes to normal operating
temperature.
3. Remove the engine oil tank filler cap, and
wipe the engine oil dipstick off with a clean
rag.
4. Insert the dipstick into the filler hole (without
screwing it in), and then remove it again to
check the oil level.
TIP
The engine oil should be between the minimum
8
and maximum level marks.
