How Often to Change Lawn Mower Oil

Your lawn mower's oil should be changed about once a year, or every 50 hours of use, and can be done easily at home.

Oil Change Steps

  2. Disconnect Spark Plug

    Before you begin any gas mower maintenance, always disconnect the spark plug and secure it off to the side so it won’t start accidentally.

  3. Remove Cap

  4. Drain Oil

    Tilt the mower on its side and drain the oil into a pan. Tilt the mower with the oil side down and the air filter up. If your mower has a drain plug on the mower deck, you can drain the oil out the bottom. Then, replace the drain plug.

  5. Refill Oil

Where to Dispose Motor Oil

Because motor oil can cause damage to the environment, properly disposing of it is essential. You should always recycle used motor oil so it can be re-refined and used in other machines. Visit Earth 911 to locate a collection center for used motor oil near you.
