Are you noticing that your lawn mower is burning oil? If so, it’s important to address the issue as soon as possible to prevent further damage to your machine.

Oil is an essential component in the function of your lawn mower, and when it starts burning, it can lead to a range of problems that can affect the performance and longevity of your mower.

We’ll talk about the common causes of lawn mower oil burning, the symptoms to look out for, and how to fix it.

We’ll also provide you with tips on how you can prevent oil burning in the future, and when it may be time to seek professional help.

The Importance of Oil in Lawn Mowers

You may not realize it, but your lawn mower needs oil to lubricate its internal parts and prevent damage from friction and heat. The oil in your lawn mower also acts as a cooling agent, ensuring that the engine does not overheat during use.

As such, it’s crucial to keep the oil level in your lawn mower topped up and to change the oil regularly. When choosing oil for your lawn mower, it’s important to consider the viscosity of the oil. Viscosity refers to the thickness of the oil and how well it flows through the engine.

Choosing the wrong viscosity can result in poor engine performance and even damage. To choose the right oil for your lawn mower, refer to your owner’s manual, which should provide guidance on the recommended viscosity range.

It’s also important to choose an oil that’s suitable for the temperature and climate in which you’ll be using your lawn mower.

Common Causes of Lawn Mower Oil Burning

Your trusty steed has been working hard all summer, but now it’s starting to show some wear and tear. One possible culprit? A sneaky saboteur called oil burning.

The most common cause of oil burning in lawn mowers is a dirty air filter or a clogged breather tube. When the air filter is clogged, it can’t allow enough air into the engine, causing it to run rich and burn oil.

Similarly, if the breather tube is clogged, it can cause pressure to build up in the crankcase, which can force oil past the piston rings and into the combustion chamber.

Another common cause of oil burning is worn piston rings or valve seals. When these components wear out, they allow oil to leak into the combustion chamber, where it is burned along with the fuel.

To prevent oil burning, it’s important to keep up with lawn mower maintenance. Change the air filter and spark plug regularly, and make sure the breather tube is clear. If you notice excessive smoke or oil consumption, check the piston rings and valve seals for wear and replace them if necessary.

Symptoms of Oil Burning in Lawn Mowers

Symptoms of Oil Burning in Lawn Mowers

When oil burns in a lawn mower, it can cause several symptoms that indicate a potential problem. One of the most obvious symptoms is smoke that emits from the engine. This smoke can range from light gray to dark black, depending on the severity of the oil burning.

Aside from smoke, you may also notice a strong burning smell coming from the mower. This smell is caused by the oil burning and can be quite unpleasant.

Oil burning in lawn mowers can have several causes, and each cause can have different consequences. One of the most common causes of oil burning is worn piston rings. When these rings wear out, oil can seep into the combustion chamber and burn, causing smoke and a burning smell.

Another common cause of oil burning is a clogged or dirty air filter. When the air filter is clogged, the engine can’t get enough air, causing it to run rich and burn oil. Regardless of the cause, it’s important to address oil burning in lawn mowers promptly to prevent further damage and potential safety hazards.

How to Check Oil Levels in Your Lawn Mower

If you’re not regularly checking the oil level in your lawn mower, chances are it’s only a matter of time before you run into some serious problems.

Checking the oil level in your lawn mower is an easy task that can save you from costly repairs or even having to replace your mower altogether.

To check the oil level, follow these simple steps:

  • Locate the dipstick on your lawn mower, which is typically near the engine.
  • Remove the dipstick and wipe it clean with a cloth.
  • Reinsert the dipstick all the way back in and then pull it out again.
  • Check the oil level on the dipstick. The oil should be at the proper level and have a consistent, clean appearance.

It’s important to check your oil level on a regular basis, as part of your mower’s maintenance schedule. You should also pay attention to the oil consistency, as oil that’s too thick or too thin can cause your mower to burn more oil than necessary.

Fixing the Problem of Oil Burning

To fix the problem of oil burning, you’ll need to take your mower to a professional who can diagnose and repair the issue, ensuring that your machine runs smoothly and efficiently like a well-oiled machine.

Burning oil is a common problem for lawn mowers, and can be caused by a variety of issues. One of the most common reasons for oil burning is a dirty air filter. A clogged air filter can cause your mower to run improperly, leading to excessive oil consumption.

To fix this, you’ll need to clean or replace your air filter regularly to ensure that it’s functioning properly.

Another common cause of oil burning is faulty spark plugs. If your mower’s spark plugs are worn out or damaged, they won’t be able to ignite the fuel properly, leading to increased oil consumption.

To fix this issue, you’ll need to replace your spark plugs with new ones. It’s important to choose the right spark plugs for your mower to ensure that they’re compatible and will work properly.

Tips on Preventing Lawn Mower Oil Burning

Keeping your lawn mower running smoothly and efficiently is crucial for a lush and healthy lawn, so it’s important to regularly maintain and care for your machine, including preventing excess oil consumption.

One of the best ways to prevent oil burning is through preventive maintenance. Regularly check and change the oil according to the manufacturer’s instructions, and make sure to keep the oil level at the proper level. Additionally, clean or replace the air filter as needed to ensure proper air flow to the engine.

Choosing the right oil is also important in preventing oil burning. Make sure to use the oil recommended by the manufacturer, and ensure it is the correct viscosity for your mower. Using the wrong oil can cause excess wear and tear on the engine, leading to oil burning.

It’s also important to properly store and handle the oil, keeping it in a clean and dry area and avoiding contamination.

When to Seek Professional Help

You might want to consider bringing in a professional for assistance if you notice any unusual sounds or smells coming from your machine. These could be signs of a damaged engine that requires more than just basic DIY troubleshooting techniques.

Here are some signs to look out for:

  1. Blue or white smoke coming from the exhaust
  2. Knocking or ticking sounds from the engine
  3. Increased oil consumption
  4. Loss of power or acceleration

If you experience any of these signs, it’s best to seek professional help. A certified technician can perform a thorough inspection and diagnose the issue accurately. Attempting to fix a damaged engine on your own can lead to further complications and costly repairs.
