Change lawnmower oil
Short answer
Each spring, warm the engine briefly, drain the old oil into a pan, and refill with the grade specified in your mower's manual.
Why It Matters
Dirty oil loses lubricating properties and shortens engine life. Most small engines hold less than a quart, so it's a 10-minute job.
Tools
- Drain pan
- Funnel
Materials
- Small-engine oil (grade per manual)
How to Do It
- Run the engine for a few minutes to warm the oil so it flows more easily when drained.
- Shut off the engine, disconnect the spark plug wire, and locate the oil drain plug or fill tube, depending on your mower's drain method.
- Tip the mower in the direction specified in your manual, or remove the drain plug, and let the old oil drain completely into the pan.
- Replace the drain plug if removed, then set the mower back on level ground.
- Reconnect the spark plug wire, then refill with the oil grade and quantity specified in your manual, using a funnel to avoid spills.
