When changing the oil in a lawn mower, take off the plug wire, drain the oil into an appropriate container and add between 18 and 20 ounces of oil. Change the oil in a lawn mower with tips from a professional landscaper in this free video on lawns and gardening.
I'm Bill Elzey with Showplace Lawns. Let's talk about changing the oil in the lawnmower. The best thing to do first of all, always when you are working on any equipment is to take the plug wire off. You don't want that thing going off on you while you have got your hands in a wrong spot. Wipe your stick off and drain the oil. Also be sure that you have something nice to put your oil in so after you drain the oil put it in an old container and take it to some equipment place or some place like that so they can dispose of the oil properly. We have drained the oil and now we are going to add the oil to the machine. Most lawn mowers will take between 18 and 20 ounces of a good 30 weight oil. Put your cap back on it and your oil is changed.
