The Harley Road Glide is a full-size touring-style motorcycle and comes with a few different engine sizes. The Road Glide uses 3 qt Harley motorcycle oil which is housed inside the crankcase. On the side of the crankcase, there is a metal cap with a thick raised edge. This cap is the dipstick that you will use to check the amount of oil inside the crankcase.
Step 1
Park the Harley Road Glide on flat, level ground. Allow the engine to run so that the oil inside the crankcase warms up. The engine should run for about 10 minutes.
Step 2
Twist the oil cap counterclockwise and pull it off the engine. Wipe the oil off the dipstick connected to the inside of the cap using the paper towel.
Step 3
Insert the dipstick into the engine and pull it back out. Look at the dipstick: If the oil level is below the hole at the top of the dipstick, add oil until the oil level is at that hole. If the oil level is at the top hole, no oil is needed.
Warning
Adding to much oil will flood the crankcase and cause serious damage to the engine.
