The crisp air, falling leaves, and the cozy scent of fireplaces signal the end of lawn mowing season. As you put your mower away for the winter, you might be wondering about the best time to change the oil. Should you do it before storing your mower, or is it better to wait until spring? This question sparks a debate among lawn care enthusiasts, each side arguing for their preferred approach.
This article delves into the pros and cons of changing your lawn mower oil before or after winter, offering insights to help you make an informed decision. We’ll explore the reasons why some advocate for a pre-winter oil change, while others suggest waiting until spring. We’ll also discuss the potential risks and benefits of each approach, ultimately helping you determine the best strategy for your mower and your personal preferences.
The Short Answer:
While there’s no universally accepted answer, the general consensus is to change your lawn mower oil before storing it for winter. This helps ensure a smooth start in the spring and reduces the risk of engine damage due to oil degradation.
Why Change the Oil Before Winter?
Storing your lawn mower with old oil exposes it to several risks.
Oil Degradation
Over time, oil breaks down. This degradation is accelerated by heat, moisture, and the presence of contaminants. During the winter, the oil sits idle in your mower, exposed to the elements. This can lead to:
- Increased Viscosity: The oil thickens, making it difficult for the engine to circulate properly.
- Formation of Sludge: Degraded oil can leave behind sludge that clogs engine parts.
- Corrosion: Moisture in the oil can lead to rust and corrosion in the engine.
Preventing Engine Damage
A clean engine with fresh oil is crucial for a smooth start-up in the spring. Old oil can cause:
- Difficulty Starting: Thickened oil makes it harder for the engine to turn over.
- Increased Wear and Tear: Sludge and corrosion can cause excessive wear on engine parts.
- Reduced Engine Life: Neglecting regular oil changes can shorten the lifespan of your mower engine.
Peace of Mind
Changing the oil before winter storage offers peace of mind. Knowing your mower has fresh oil gives you confidence that it will be ready to go when the spring arrives.
Is It Okay to Wait Until Spring?
Some argue that changing the oil in the spring is sufficient. However, this approach comes with potential drawbacks:
Increased Engine Wear
Storing your mower with old oil, even for a short period, can still lead to some degradation and increased wear on engine parts.
Difficulty Starting
If the oil has thickened significantly, starting the engine in the spring can be challenging, potentially causing damage.
Potential for Sludge Build-up
The longer old oil remains in the engine, the greater the risk of sludge buildup. This can lead to clogging and reduced engine efficiency.
Factors to Consider:
While the general recommendation is to change the oil before winter, the best approach depends on your specific circumstances:
Mower Usage
If you rarely use your mower, the oil is less likely to degrade quickly. In this case, waiting until spring might be acceptable.
Storage Conditions
How you store your mower impacts oil degradation. If it’s kept in a dry, temperature-controlled environment, the oil will be less susceptible to damage.
Your Comfort Level
If you’re unsure about the condition of your oil or prefer to be extra cautious, changing it before winter is the safer option.
How to Change Your Lawn Mower Oil:
- Safety First: Always wear safety glasses and gloves when working with oil.
- Warm Up the Engine: Run the mower for a few minutes to warm the oil and allow it to flow more freely.
- Locate the Drain Plug: Find the drain plug at the bottom of the engine crankcase.
- Place a Drain Pan: Position a drain pan underneath the plug to catch the used oil.
