The first sign of spring is often the whirring of lawn mowers as homeowners tackle their overgrown yards. But before you start mowing, it’s essential to make sure your mower is in tip-top shape. One crucial maintenance task is changing the oil. This article will walk you through the process of changing the oil in your lawnmower, from gathering the necessary tools to disposing of the used oil properly. We’ll cover everything you need to know, so you can keep your lawn mower running smoothly all season long.
The Importance of Changing Your Lawn Mower Oil
Like any engine, your lawn mower’s engine relies on oil for lubrication. This oil prevents metal parts from rubbing against each other and wearing down. Over time, the oil breaks down and becomes contaminated with dirt, metal shavings, and other debris. This dirty oil loses its ability to lubricate effectively, increasing friction and causing damage to your engine. Regular oil changes ensure that your lawnmower operates efficiently, reducing wear and tear and extending its lifespan.
Getting Started: Tools and Materials
Before you begin, gather the following tools and materials:
- New lawn mower oil: The type of oil you need will depend on your mower’s engine. Consult your owner’s manual for the recommended oil viscosity.
- Oil drain pan: This will catch the used oil as you drain it.
- Wrench: You’ll need a wrench that fits the oil drain plug.
- Oil filter wrench (optional): Some lawn mowers have oil filters that require a special wrench for removal.
- Gloves: Protect your hands from oil and dirt.
- Rag or paper towels: For cleaning up spills.
- Safety glasses: Protect your eyes from splashes.
- Funnel: To help pour the new oil into the engine.
- Old container: To dispose of the used oil safely.
Step-by-Step Guide to Changing Your Lawn Mower Oil
1. Prepare the Mower and Workspace
- Safety First: Wear safety glasses to protect your eyes from any oil splashes. Park your lawn mower on a level surface. Make sure the engine is cool before you start working.

Do I need to warm up my lawn mower before changing the oil?
It’s generally recommended to warm up your lawn mower for a few minutes before changing the oil. This allows the oil to become more fluid and helps it drain out more easily. However, be cautious and do not run the engine for too long.
If the engine is very hot, wait for it to cool down slightly before proceeding.
How do I dispose of used oil properly?
Used oil should never be poured down the drain or into the ground. It’s important to dispose of it properly to prevent environmental pollution. You can take your used oil to a designated oil recycling center or a local mechanic who can dispose of it for you.
Check with your local government or waste management company for details on oil recycling options in your area. They may have specific guidelines or designated drop-off locations.
How do I know if I’ve put the correct amount of oil in my lawn mower?
Most lawn mower engines have a dipstick that allows you to check the oil level. The dipstick is usually located near the top of the engine crankcase. After adding new oil, remove the dipstick and wipe it clean. Insert it back into the dipstick tube and remove it again. The oil level should be between the “Full” and “Add” marks on the dipstick.
If the oil level is too low, add more oil until it reaches the “Full” mark. If the oil level is too high, remove some of the excess oil with a syringe or suction tool.
