Place the oil filler cap back into the oil filler hole and twist it clockwise until it is snug,

Locate, pull out, and wipe off the end of the engine oil dipstick. The dipstick has a yellow handle.

Place the oil dipstick back into its hole all the way and remove it again. Note the oil level on the dipstick; it should be between the two bumps. If the oil is below the bottom bump you will need to add oil, and if it is above the top bump you will need to drain some oil.

Adjust the oil level as necessary and put the dipstick back when you are done.
