Proper maintenance of your two-wheeler engine oil is crucial for optimal performance and longevity. However, many motorcycle owners make avoidable mistakes when changing their engine oil. These errors can lead to reduced engine efficiency, increased wear and tear, and even severe damage. To ensure your bike runs smoothly, here are the most common mistakes to avoid when changing motorcycle engine oil.
1. Using the Wrong Type of Engine Oil
Not all engine oils are the same. Motorcycle engines require specific oil formulations that differ from car oils. Using the wrong oil can lead to excessive wear, overheating, and poor lubrication. Always check your motorcycle’s manual for the recommended two-wheeler engine oil specifications.
How to Avoid This Mistake:
Use the recommended oil viscosity and grade (e.g., 10W-40 or 20W-50).
Choose oil that meets JASO MA or JASO MA2 standards for motorcycles.
Avoid using automotive engine oil, as it lacks the necessary friction modifiers for motorcycle clutches.
2. Not Warming Up the Engine Before Draining the Oil
Cold oil is thicker and does not ...
... drain completely, leaving sludge and contaminants in the engine. Draining oil without warming the engine leads to incomplete removal and can result in poor lubrication.
How to Avoid This Mistake:
Start your motorcycle and let it run for 5–10 minutes to warm up the oil.
Ensure the engine is warm but not too hot to prevent burns.
3. Over-Tightening or Under-Tightening the Drain Bolt
The drain bolt plays a crucial role in keeping the oil contained. Over-tightening can strip the threads, causing leaks and expensive repairs. Under-tightening can lead to oil leaks and engine damage.
How to Avoid This Mistake:
Use a torque wrench to tighten the drain bolt to the manufacturer’s specified torque setting.
Inspect the washer and replace it if worn out to prevent leaks.
4. Neglecting to Replace the Oil Filter
The oil filter traps dirt, debris, and metal particles that can damage your engine. Using an old filter reduces oil flow and allows contaminants to circulate.
How to Avoid This Mistake:
Always replace the oil filter during each oil change.
Choose a high-quality oil filter that meets OEM specifications.
Lubricate the rubber gasket of the new filter with fresh oil before installation.
5. Using Too Much or Too Little Oil
Adding too much oil can cause excessive pressure, leading to oil foaming and poor lubrication. Too little oil results in increased engine friction and overheating.
How to Avoid This Mistake:
Refer to the owner’s manual for the correct oil capacity.
Use the oil dipstick or sight glass to ensure the right oil level.
Add oil gradually and check levels before sealing the system.
6. Failing to Check for Leaks After Changing Oil
Skipping a leak check can result in unnoticed oil loss, leading to severe engine damage due to insufficient lubrication.
How to Avoid This Mistake:
Inspect the drain plug, oil filter, and casing for leaks after refilling the oil.
Run the engine for a few minutes and check for oil seepage.
Tighten bolts if necessary, but avoid over-tightening.
7. Ignoring Oil Change Intervals
Many riders extend oil change intervals beyond manufacturer recommendations, leading to oil degradation and increased engine wear.
How to Avoid This Mistake:
Change the oil as per the motorcycle manual, typically every 3,000–5,000 km.
If you ride in extreme conditions (heat, heavy traffic, off-road), change the oil more frequently.
Use fully synthetic oil if you prefer extended intervals between changes.
8. Not Cleaning the Oil Drain Plug
The drain plug attracts metal shavings and debris that can re-enter the engine if not cleaned properly.
How to Avoid This Mistake:
Wipe the drain plug clean before re-installing it.
If your drain plug has a magnetic tip, ensure it's free of metal debris before reusing.
9. Forgetting to Dispose of Old Oil Properly
Used engine oil is hazardous and should never be dumped in drains or soil. Improper disposal harms the environment and may result in legal consequences.
How to Avoid This Mistake:
Collect used oil in a sealed container.
Take it to a recycling center or an authorized disposal facility.
Avoid mixing used oil with other fluids like coolant or fuel.
10. Not Following a Proper Sequence in the Oil Change Process
Skipping steps or performing them in the wrong order can lead to incomplete drainage, contamination, or oil overfill.
How to Avoid This Mistake:
Warm up the engine.
Remove the drain plug and drain the oil completely.
Replace the oil filter.
Reinstall and tighten the drain plug.
Refill with fresh oil.
Check oil levels and leaks.
Dispose of old oil properly.
Conclusion
Changing your two-wheeler engine oil properly is crucial for maintaining engine efficiency and prolonging your motorcycle’s lifespan. Avoiding these common mistakes ensures optimal performance and prevents costly repairs. Always follow manufacturer guidelines, use quality oil and filters, and check for leaks after every oil change.
