How to change oil in lawnmower?
Before you change the oil, you will need to determine whether you have an oil drain plug or whether you will need to turn the lawnmower over. If it has a drain plug, unscrew it and let the oil drain into a pan. If no, unscrew the cap and turn the mower away from the air filter and drain about 3/4 of the oil into a pan for about 1 minute. Look for a tag on the mower to tell you what kind of oil to replace, pour it in, cap and go!
