How to check motorcycle oil level: step by step
Knowing how to check motorcycle oil is a basic skill every rider should have. It lets you spot when a quick top-up is needed, though it won’t tell you when a full oil change is due. For that, see XLMoto’s ultimate guide to motorcycle oil changes. Checking regularly only takes a few minutes and helps keep your bike running smoothly between services.
Steps to Checking Your Motorcycle Oil Level
Here’s how to make sure your motorcycle oil level stays within the safe range:
1. Warm up the engine
Start by taking your motorcycle for a short ride of a few minutes. This helps circulate the oil through the engine and ensures the reading will be accurate. Without this step, oil may still be pooled in certain parts of the engine, giving you a false measurement.
2. Let the oil settle
Once the ride is complete, turn the engine off and wait around five minutes or so. This allows the oil to drain back into the sump. Checking too soon can make the level appear higher than it actually is.
3. Keep the bike level
Place the bike upright on flat ground. You cannot get a precise motorcycle oil level reading if the bike is leaning on its side stand or parked on a slope. Use a paddock stand if you have one, or ask a friend to hold the bike steady.
4. Use the dipstick or sight glass
If your bike has a dipstick, remove it, wipe it clean, then reinsert it, and pull it out again to see where the oil reaches. For motorcycles with a sight glass, check that the oil level sits between the minimum and maximum marks. Whichever method you use, the bike must be fully upright for an accurate check.
5. Top up carefully if needed
If the oil is low, add small amounts of motorcycle engine oil, no more than 100 ml at a time. Always use the correct grade of oil recommended for your bike, which you can find in your motorcycle owner's manual. Overfilling the oil can be just as damaging as running low, so take your time and measure carefully.
6. Recheck the oil level
Wait a minute or two after topping up to let the oil settle again. Then recheck using the dipstick or sight glass and repeat the process until the level is correct. Some riders also run the engine for a minute and check one final time, which can confirm everything is balanced before the next ride
How to Check Motorcycle Oil Level on Different Engine Types
After learning how to check motorcycle engine oil, it helps to understand how the engine type can affect the process. Most motorcycles use wet sump engines, where the oil collects in the sump beneath the engine. In this case, you can check the motorcycle oil level by following the standard steps we outlined.
Some sports bikes, off-road models and touring motorcycles use dry sump engines instead. Here, the oil is stored in an external tank instead of the sump. The process is similar, but there’s one key difference: once the bike has warmed up, you should check the motorcycle oil level straight away, rather than waiting a few minutes. This gives you the most accurate reading.
Signs Your Motorcycle Has Low Oil
So, how often to check motorcycle oil? A good rule of thumb is before every long trip, especially in summer, and roughly every 500 miles if you only ride occasionally. It’s also smart to check after a high-speed motorway run or when you’re already maintaining the bike. For example, you can clean your motorcycle and then check the oil as part of the same routine.
Watch out for signs that your motorcycle oil level might be too low. Check it straight away if you notice any of these:
The low oil light comes on, even briefly.
The engine makes unusual sounds or starts grinding.
Changing gear feels stiffer than normal.
You see more exhaust smoke than usual.
The engine seems hotter than expected.
Common Mistakes When Checking Motorcycle Oil Level
One mistake riders make is checking the oil while the motorcycle is leaning. Doing this gives you an inaccurate reading, as oil pools to one side of the sump. Another is not waiting long enough after turning off the engine, since the oil needs a few minutes to settle back into the sump. The exception is with dry sump systems, where the oil is held in a separate tank and should be checked right away. A third mistake is adding too much oil at once. Always top up gradually and recheck, rather than risk overfilling.
Now that you’ve checked your motorcycle oil level, you’re set to get back on the road with your engine in good shape. If you need top-ups, you can find oil, fluids and lubricants at XLMoto to keep your bike running smoothly.
