4 Signs Your Motorcycle Is Due for an Engine Oil Change

4 Signs Your Motorcycle Is Due for an Engine Oil Change

Not sure when to change your motorcycle’s engine oil? Here are a few signs that your bike might be asking for fresh lubrication.

One of the most important parts of motorcycle maintenance is knowing when it’s time to change the engine oil. It helps keep the engine components properly lubricated, reduces friction and allows everything to work as it should.

But how do you know when your motorcycle is due for a fresh oil change? Here are some signs to look out for.

1. The Engine Sounds Rougher or Louder

Has your motorcycle suddenly started sounding louder or rougher than usual? Old or contaminated engine oil may not lubricate the moving parts as effectively as fresh oil. As lubrication decreases, friction between components can increase, which may make the engine feel and sound rougher.

If your bike has suddenly become noisier and the engine also feels less responsive, it might be time to check the oil and service the motorcycle.

2. Your Bike Starts Using More Fuel

Finding yourself at the petrol station more often than usual? When the engine isn’t running as smoothly, it may have to work harder, which can contribute to higher fuel consumption.

However, fuel economy can also be affected by other things such as tyre pressure, riding habits, engine condition and the fuel system. So, if your motorcycle suddenly becomes more thirsty, it’s worth checking the engine oil as part of a proper inspection.

3. The Engine Oil Looks Very Dark

Another easy thing to check is the condition of your engine oil. If your motorcycle has a dipstick, check the oil according to the procedure recommended by the manufacturer. Engine oil naturally becomes darker as it is used because it collects contaminants and by-products from the combustion process.

That said, dark oil doesn’t automatically mean it needs to be changed immediately. The best approach is to follow your motorcycle manufacturer’s recommended service interval and mileage. If you’ve already reached the recommended interval, don’t put off the oil change.

4. You Notice a Burnt Smell

A strong burnt or unusual smell coming from around the engine is something you shouldn’t ignore. Old oil, low oil levels or other mechanical issues can affect how effectively the engine is lubricated and cooled.

A burnt smell can also come from oil leaking onto hot components or other problems that have nothing to do with the engine oil itself. So, if the smell continues after an oil change, get the motorcycle checked to find out what’s actually causing it.

Should You Follow Mileage or Time?

So, should you change your engine oil based on mileage or time? The simple answer is whichever comes first, based on your motorcycle manufacturer’s service schedule.

For example, if your manufacturer recommends an oil change at a certain mileage or after a specific period, don’t wait until both conditions are met. Following the recommended service schedule helps keep the engine running properly and can contribute to a longer motorcycle lifespan.
