Before checking the oil, warm up the engine to the normal operating temperature and be sure it is parked on level ground. Turn the engine off.

Wait five minutes, then remove the dipstick, wipe it off, fully reinsert the dipstick and withdraw it again. Then note the highest level the oil has reached on the dipstick. It should be between the upper ("F") and lower ("L") range.

WARNING:

Be very careful not to touch the radiator hose when checking the engine oil as it may be hot enough to burn you.
