The video above shows you how to add oil to your 2003 Hummer H2. Before adding oil to your H2, make sure that your engine was cold and that your car was parked on a level surface when you checked the oil level otherwise you won't be able to tell if your H2 has a low oil level. For most Hummers, if your oil level is at the minimum mark on your dipstick, you should add about a quart of oil. If you are unsure how much oil to add to your H2, add a little bit at a time and check your dipstick frequently. This video shows you where the oil fill cap is located on your H2 and how to add oil. Adding too much oil to your H2 can be harmful, so it is easiest to add a little at a time.
If you add too much oil to your H2, you will need to remove some by loosening the drain plug underneath your engine - check out our video on how to change your oil & oil filter to see how to remove the excess oil.
