How to Drain Oil from a Lawn Mower Briggs & Stratton: A Step-by-Step Guide?

The satisfying whir of a well-maintained lawn mower is a summer soundtrack. But just like any machine, your Briggs & Stratton lawn mower needs regular maintenance, and that includes changing the oil. This article will guide you through the process of draining the oil from your lawn mower, ensuring a smooth-running engine and a longer lifespan. We’ll cover everything from the necessary tools to the proper disposal of used oil, so you can confidently handle this essential maintenance task.

Overview: Draining the oil from your Briggs & Stratton lawn mower is a relatively straightforward process. It involves locating the oil drain plug, positioning the mower on a level surface, and allowing the oil to flow into a designated container. This routine maintenance helps to prevent engine wear and tear, ensuring optimal performance.

Finding the Oil Drain Plug: The First Step

Before you can drain the oil, you need to locate the oil drain plug. This is usually found on the bottom of the engine, often near the crankshaft. Here’s how to find it:

1. Identify the Engine:

* Your Briggs & Stratton lawn mower's engine will have a rectangular or round shape, usually with a black or grey metal casing. 
* Look for a Briggs & Stratton logo or a model number on the engine housing.

2. Locate the Drain Plug:

* **Look for a small, hexagonal-shaped plug** on the underside of the engine. 
* It may be positioned near a vertical fin on the engine block, making it easier to identify.

3. Check for Additional Components:

* **Some models might have a drain plug with a built-in dipstick.** This combines the oil drain and level check functions. 
* **Others might have a separate dipstick for checking oil levels.** In these cases, the drain plug will be a separate component.

Gathering Your Tools and Materials

Now that you’ve located the drain plug, it’s time to gather your tools and materials for the oil change. Here’s what you’ll need:

  • A drain pan: This is crucial to catch the used oil. Look for a pan that’s large enough to accommodate the entire volume of oil in your mower.
  • A wrench or socket: The size will depend on the drain plug on your specific lawn mower. Check the size before you start.
  • A pair of gloves: Protect your hands from the oil.
  • New oil: Choose oil specifically designed for your lawn mower. Consult your owner’s manual for the recommended type and viscosity.
  • Funnel: Helps you pour the fresh oil back into the engine.
  • Paper towels or rags: For cleaning up spills.

Draining the Oil: A Step-by-Step Guide

With your tools gathered, it’s time to drain the oil:

1. Positioning the Lawn Mower:

* **Park the mower on a flat, level surface.**  This ensures that all the oil will drain out.

2. Warm Up the Engine (Optional):

*  **Slightly warming up the engine** can make the oil flow more easily.  Run the mower for a few minutes, but avoid over-heating. 
* **This step isn't mandatory, but it can make the process smoother.**

3. Remove the Drain Plug:

*  **Place your drain pan directly under the drain plug.**
*  **Carefully loosen the drain plug** using the appropriate wrench or socket.  Turn counter-clockwise to remove it.
* **Be careful not to drop the drain plug into the pan.**

4. Drain the Oil:

* **Allow the oil to drain completely.**  This may take a few minutes. 
* **Once the flow slows to a drip, you can remove the drain pan.**

Replacing the Oil Drain Plug

After the oil has drained, it’s time to re-install the drain plug:

1. Cleaning the Drain Plug and Thread:

* **Wipe the drain plug and the threads** with a clean cloth or paper towel.  This will remove any debris and prevent leaks.

2. Tightening the Drain Plug:

* **Screw the drain plug back into the hole.**  Don't overtighten it, as this could damage the threads. 
* **Tighten the plug snugly by hand.**

Filling with New Oil

Now that the old oil is out and the drain plug is secure, you can add new oil:

1. Checking the Owner’s Manual:

* **Consult your owner's manual** to find the exact amount of oil needed for your lawn mower engine.

2. Using the Dipstick:

* **If you have a dipstick**, insert it into the dipstick tube. 
* **Wipe the dipstick clean.**
* **Insert it back into the tube and remove it again to check the oil level.**
* **Add oil until the oil level is at the "full" mark on the dipstick.**

3. Using a Funnel (If Necessary):

* **If your lawn mower doesn't have a dipstick**, use a funnel to pour the new oil into the oil fill hole.  
* **Be careful not to overfill the engine.**

Disposing of Used Oil:

Properly disposing of used oil is essential for environmental protection:

1. Finding a Collection Point:

* **Check with your local municipality or waste disposal company** to find a designated oil collection point. 
* **Many automotive stores and recycling centers offer oil disposal services.**

2. Proper Storage:

* **Store used oil in a sealed container** to prevent spills. 
* **Keep the container out of reach of children and pets.**

FAQs

1. How often should I change the oil in my Briggs & Stratton lawnmower?

The frequency of oil changes for your Briggs & Stratton lawnmower depends on the usage and the type of oil you’re using. Generally, it’s recommended to change the oil every 25 hours of operation or once a year, whichever comes first. If you use your lawnmower frequently in demanding conditions, like high temperatures or heavy loads, it’s best to change the oil more often.

If you use high-quality oil that meets the specifications for your mower, you can potentially extend the time between oil changes. However, always refer to your lawnmower’s manual for specific recommendations and maintenance schedules.

6. Can I drain the oil while the engine is still hot?

It’s best to let the engine cool down completely before draining the oil. This will allow the oil to settle in the sump and ensure that you drain as much of it as possible. Additionally, hot oil can cause burns, so letting it cool down before handling it is a safety precaution.

If you must drain the oil while the engine is still warm, be extremely careful and wear appropriate protective gear.

7. What should I do after draining the oil?

After draining the oil and replacing the drain plug, check for any leaks. If everything is secure, you can then add the recommended amount of new oil. You should also replace the oil filter if it has one.

After adding the new oil, start the engine and let it run for a few minutes to allow the oil to circulate. Then check the oil level again and top it off if necessary. Be sure to dispose of the used oil and oil filter properly.
