How to Change the Oil on a Motorcycle
Why Oil Changes Matter for Your Motorcycle
Oil keeps your motorcycle engine running smoothly. Over time, oil breaks down and gets dirty, which means it can't protect your engine as well. Regular oil changes help your motorcycle last longer and run better. Think of oil as the lifeblood of your engine—without clean oil, parts wear out faster and your bike won't perform at its best.
Most motorcycles need an oil change every 3,000 to 6,000 miles, though this varies by model. Some newer bikes can go longer between changes. Check your owner's manual to see what's right for your bike. Keeping up with oil changes is one of the easiest ways to protect your investment and avoid costly repairs down the road.
Learning to change your own oil saves money and gives you a better understanding of how your motorcycle works. It's a skill that takes less than an hour once you're familiar with the process.
What You'll Need
Before you start, gather these items so you have everything within reach:
- New oil (the correct type and amount for your motorcycle)
- A new oil filter
- An oil drain pan
- A wrench or socket set
- An oil filter wrench
- Rags or paper towels
- Jack or center stand (to lift the motorcycle safely)
- Safety glasses
- Work gloves (optional but helpful)
- A container for disposing of old oil
Your owner's manual will tell you exactly which oil type and weight your motorcycle needs. This is important because different motorcycles have different requirements. Using the wrong oil can hurt your engine's performance. Most motorcycle shops can tell you the right oil if you're not sure, or you can look up your bike's year and model online.
Having everything ready before you start makes the job go faster and smoother. You won't have to stop halfway through to hunt for a tool or run to the store for something you forgot.
Preparing Your Motorcycle
Start with a warm engine—not hot. Warm oil drains better than cold oil because it flows more easily. Run your motorcycle for a minute or two, then turn it off and wait a few minutes. This gives the oil time to warm up without getting so hot that it burns you.
Place your motorcycle on a center stand or use a jack to lift it safely. Make sure it won't tip over. If you're using a jack, place it on solid ground and double-check that the bike is stable. A falling motorcycle can cause serious injury and damage.
Put your drain pan under the engine where the oil drain plug is located. Position it so the draining oil will flow into the pan and not onto your garage floor. Old oil can stain concrete, so it's worth taking a moment to get this right.
Put on your safety glasses and work gloves if you have them. Even though this is a simple job, protecting your eyes and hands is always a good idea when working with machinery.
Draining the Old Oil
Find the oil drain plug on the bottom of your engine. It's usually a bolt with a hex head. Use your wrench to loosen it by turning counterclockwise. Once it's loose enough, carefully unscrew it by hand. Go slowly so you don't drop it into the drain pan.
Let the old oil drain completely into the pan. This may take several minutes. Be careful—the oil may still be warm, even after you've waited. If it's too hot to touch, wait a bit longer before handling the drain plug.
Once the oil stops dripping, wipe the drain plug clean with a rag. Check if your plug has a crush washer (a small metal ring). If it does, replace it with a new one. This helps prevent leaks. Crush washers are inexpensive and often come with new oil filters or can be bought separately.
Screw the drain plug back in by hand first, then tighten it with your wrench. Don't overtighten—snug is enough. If you tighten it too much, you can strip the threads and cause a leak that's harder to fix.
Replacing the Oil Filter
Locate your oil filter. It's usually a cylindrical part on the side of the engine. On some motorcycles, it's mounted vertically; on others, it's horizontal. Your owner's manual will show you exactly where it is on your bike.
Place your drain pan underneath it to catch any oil that drips out. Use an oil filter wrench to loosen the filter by turning it counterclockwise. Once loose, unscrew it by hand and let any remaining oil drip into the pan. Be ready—there's usually a little oil still in the filter.
Wipe the filter mounting surface clean with a rag. Remove any old rubber gasket material or dirt. A clean surface helps the new filter seal properly and prevents leaks.
Take your new filter and coat the rubber gasket (the ring on top) lightly with new oil. This helps create a good seal when you install it. Screw the new filter on by hand until the gasket touches the engine, then turn it another three-quarter turn. Don't use a wrench for this—hand-tight is the correct way. Over-tightening can damage the filter and make it hard to remove next time.
Adding New Oil
Remove your oil filler cap on top of the engine. It's usually marked with an oil can symbol. Pour in the new oil slowly, checking the level as you go. Most motorcycles have a sight glass (a clear window on the side of the engine) or a dipstick to show the oil level.
Fill until the oil reaches the proper level shown in your owner's manual. Don't overfill. Too much oil can damage your engine just like too little oil can. If you're not sure about the level, it's better to add a little less and check again after you run the engine.
Replace the oil filler cap and make sure it's tight. A loose cap can let dirt into your engine or cause oil to leak out.
Checking Your Work
Start your motorcycle and let it run for 30 seconds. This circulates the new oil through the engine and helps the new filter fill with oil. You may see the oil pressure light come on briefly—this is normal. It should go out once the new oil circulates.
Turn off the engine and wait a minute or two. This allows the oil to settle back into the pan so you can get an accurate reading.
Check the oil level again using the sight glass or dipstick. Add a little more if needed to reach the proper level. It's common to need a small amount more after the first run because the new filter holds some oil.
Look under the engine for any leaks around the drain plug and filter. If you see drips, tighten these connections slightly. A small drip might mean the connection isn't quite tight enough. If tightening doesn't stop the leak, you may need to replace the crush washer on the drain plug.
Disposing of Old Oil
Never pour old oil down the drain or into the ground. Used oil is toxic and harms the environment. Take it to a recycling center, auto parts store, or service station that accepts used oil. Most places take it for free, and some even pay you a small amount for it.
You can also dispose of the old oil filter at these same locations. Many recycling centers have a separate bin for oil filters. If you're unsure where to take your old oil, search online for "used oil recycling near me" or call your local waste management facility.

Frequently Asked Questions
How often should I change my motorcycle's oil?
Most motorcycles need an oil change every 3,000 to 6,000 miles. However, this varies depending on your bike's make and model, the type of oil you use, and your riding habits. Synthetic oil often lasts longer than conventional oil. Always check your owner's manual for the recommended interval for your specific motorcycle. If you ride hard or in dusty conditions, you may need to change your oil more often.
What happens if I use the wrong oil in my motorcycle?
Using the wrong oil can hurt your engine's performance and durability. Different motorcycles have different oil requirements based on their engine design and cooling system. Using oil that's too thick can make your engine work harder and reduce fuel economy. Oil that's too thin may not protect your engine properly, leading to faster wear. Always use the oil type and weight specified in your owner's manual to keep your engine running smoothly.
Can I change my motorcycle's oil without a center stand or jack?
You need some way to safely lift your motorcycle to reach the drain plug and filter. A center stand, side stand with a block, or a motorcycle jack are all options. Never work under a motorcycle that's only on a side stand—it's not stable enough. If your bike doesn't have a center stand, invest in a small jack or lift designed for motorcycles. Safety is more important than saving a few dollars on equipment.
What should I do if oil is still leaking after I tighten the drain plug?
If tightening the drain plug doesn't stop the leak, the crush washer may be worn out or damaged. Drain the oil again, remove the plug, and replace the old crush washer with a new one. Crush washers are inexpensive and create a tight seal that prevents leaks. If you've replaced the washer and the leak continues, the threads on the drain plug or engine may be damaged, and you may need professional help.
