A plastic measuring jug can help you decide how much to add. Small lawnmowers need between 15 and 24 ounces while riding mowers need 48-64 ounces.
When should the oil be changed?
For small mowers, it is usually only necessary to change the oil once every 50 hours or once per season. For riding mowers, it is recommended to change the oil every 100 hours.
