7. Check oil level: When checking the engine oil,
remove the oil fill plug/dipstick and wipe it clean.
Thread the oil fill plug/dipstick all the way back in and
then remove and check the oil level on the oil fill plug/
dipstick.
• Acceptable Oil Level – Oil is visible on the
crosshatches between the H and L lines on the oil
fill plug/dipstick (see Figure 14).
• Low Oil – Oil is below the L line on the oil fill plug/
dipstick.
If oil level is below
this line it is too
low to operate.
