Easy Guide: How to Change the Oil on a Push Mower

How to Change Oil in Your Push Mower - YouTube

Changing the oil on your push mower is essential for keeping it in good working condition. Regular oil changes help extend the life of the engine and ensure it runs smoothly. In this guide, we’ll walk you through the process step-by-step, making it easy even if you're not a seasoned mechanic.

Why Changing Your Push Mower's Oil is Important

Before we dive into the how-to, let’s talk about why it’s crucial to change your mower's oil regularly. Over time, oil breaks down and becomes contaminated with dirt, debris, and combustion by-products. This dirty oil can cause excessive wear and tear on the engine, reducing its efficiency and lifespan. By changing the oil, you ensure that your mower runs smoothly and efficiently, season after season.

Tools and Materials You'll Need

To get started, gather the following tools and materials:

  • New oil (check your mower’s manual for the recommended type and amount)
  • Oil drain pan
  • Funnel
  • Clean cloth or rag
  • Wrench or socket set (depending on your mower model)
  • Safety gloves
  • Oil filter (if your mower has one)

Step-by-Step Guide to Changing Your Push Mower's Oil

1. Preparation

First things first, ensure your mower is on a flat surface. Run the engine for a few minutes to warm up the oil, making it easier to drain. Then, turn off the engine and disconnect the spark plug to prevent accidental starts.

2. Drain the Old Oil

Place the oil drain pan under the mower. If your mower has an oil drain plug, use a wrench or socket to remove it and let the oil drain into the pan. If there’s no drain plug, you’ll need to tip the mower on its side, with the air filter and carburetor facing up to avoid contamination, and drain the oil through the fill hole.

3. Replace the Oil Filter (If Applicable)

Some push mowers have an oil filter. If yours does, remove the old filter and replace it with a new one, following the manufacturer’s instructions. Make sure to apply a thin layer of oil to the gasket of the new filter to ensure a proper seal.

4. Add New Oil

Once the old oil is completely drained, replace the drain plug or return the mower to its upright position. Using a funnel, pour the new oil into the fill hole. Be sure not to overfill; check the oil level with the dipstick (if your mower has one) to ensure it's at the correct level.

5. Clean Up

Wipe any spilled oil off the mower with a clean cloth or rag. Reconnect the spark plug, and you’re ready to go!

Tips for Maintaining Your Push Mower

  • Regular Checks: Check the oil level before each mowing session and top up if necessary.
  • Change Frequency: Change the oil at least once a season, or after every 50 hours of use.
  • Air Filter: Clean or replace the air filter regularly to ensure optimal engine performance.
  • Blade Maintenance: Sharpen or replace the mower blades to keep your lawn looking neat and healthy.


How often should I change the oil in my push mower? You should change the oil at least once per mowing season or every 50 hours of use, whichever comes first.

What type of oil should I use for my push mower? Consult your mower’s manual for the recommended oil type. Most push mowers use SAE 30 or 10W-30 oil.

Can I use synthetic oil in my push mower? Yes, synthetic oil can be used in most push mowers and may provide better performance and protection.

What should I do with the old oil? Take the used oil to a local recycling center or auto shop that accepts used oil. Never dispose of it in the trash or down the drain.

Final Thoughts

Changing the oil on your push mower is a simple task that can make a big difference in its performance and longevity. By following this guide, you'll keep your mower running smoothly and efficiently, ready to tackle your lawn care needs.
