Locate and remove the oil dipstick. It is in front of the valve cover, sticking out of the exhaust manifold's heat shield.

Wipe off the oil dipstick, reinsert it into its hole and remove it again.

Check the oil level on the end of the dipstick. It should be between the two holes or slightly above the top one.

This is not your actual oil level, but a pre-check to make sure the engine will not run dry when you first start it. The oil level will drop slightly after the first run when oil fills the new oil filter.

Add oil if the oil level is below the bottom hole of the dipstick. Place the oil dipstick all the way back in its hole.
