How to Change Motorcycle Engine Oil at Home: A Beginner's Guide

Changing your motorcycle's engine oil is one of the easiest and most rewarding jobs you can do yourself. It takes under an hour, saves labour costs, and guarantees the right oil goes in. Here's how to do it properly.

Before you start: the right oil

• Grade: use the viscosity grade in your owner's manual (for example, 10W-30 or 10W-40).
• Specification: most motorcycles with a wet clutch need oil rated JASO MA or MA2. Scooters with a dry CVT clutch may specify JASO MB. Car oils can contain friction modifiers that make a motorcycle clutch slip.
• Quantity: check the manual for the capacity with and without a filter change.
• Genuine product: counterfeit oil is a real problem. Buy from reputable sellers and check seals and packaging.

Tools and supplies

• A spanner or socket for the drain bolt.
• A drain pan or container large enough for the old oil.
• A new crush washer for the drain bolt, if your bike uses one.
• A new oil filter and O-ring, if due.
• A funnel, rags and gloves.
• A torque wrench if you have one — overtightening the drain bolt is a common and expensive mistake.

Step by step

1. Warm the engine. Ride for five minutes or let it idle until warm — not hot. Warm oil drains faster and carries more dirt with it. Be careful: the exhaust and engine can burn you.
2. Park on level ground, on the centre stand if your bike has one, and switch off the engine.
3. Remove the filler cap. This lets air in so the oil drains smoothly.
4. Place the drain pan under the drain bolt, which is at the lowest point of the engine. Don't confuse it with other bolts — check the manual.
5. Undo the drain bolt and let the oil drain completely. Keep your hand clear of the stream.
6. Change the filter if due. Remove the cover or spin-on filter, let it drain, and fit the new one with its O-ring lightly oiled. Make sure any springs and washers go back in the right order.
7. Refit the drain bolt with a new crush washer. Tighten to the torque in the manual — firm, but not forced.
8. Refill through the funnel with slightly less than the stated quantity.
9. Check the level. Refit the cap, start the engine for a minute, switch off, wait a couple of minutes, then check the level with the bike upright using the sight glass or dipstick as the manual describes. Top up to the correct mark.
10. Check for leaks around the drain bolt and filter cover, and again after your first ride.
11. Record it — note the date and odometer reading.

Oil filter: change it or not?

Changing oil without changing the filter leaves some old, dirty oil and trapped contaminants in the engine. Follow the manual's filter interval; many riders change the filter at every second oil change or every change, depending on the model. If your bike has a mesh strainer, clean it at the interval specified.

Common mistakes to avoid

• Overfilling — too much oil can cause leaks and foaming.
• Checking the level on the side stand, which gives a false reading on many bikes.
• Reusing a flattened crush washer.
• Stripping the drain bolt thread by overtightening.
• Mixing different oils.

Dispose of used oil responsibly

Used engine oil is toxic and pollutes soil and water. Never pour it into drains or onto the ground. Collect it in a sealed container and hand it to a workshop or collection point that recycles it.

How often?

Follow your owner's manual. If you ride mainly in heavy city traffic, dusty conditions or short trips, use the shorter "severe conditions" interval where the manual gives one. For more on routine care, see our motorcycle maintenance guide.
