Even the best motorcycle oil can only protect your engine if you keep it at the right level. We explain how to top off your engine oil quickly and safely.
Topping off motorcycle engine oil
If the inspection window or dipstick tells you that your oil level is low, but that the oil is still in good condition, it's a great idea to top off your oil as soon as possible.
The first step in doing this is to make sure you add the right grade of oil. Your bike's user manual can help with this.
Once you have your oil, make sure your bike is again parked on level ground and on a centerstand or paddock stand. Your engine should be cool, and you should wait at least 30 minutes after a hard ride, or 10 minutes after idling your engine, to give the oil time to drain fully back into the sump.
Now it's time to unscrew and remove the oil filler cap, and place a long-neck funnel into the hole. You should then add a small amount of fresh oil, and then wait a minute or two for it to arrive in the sump.
Then, check the level again using the inspection window or dipstick, and keep adding oil in small amounts until you are happy with the level. Bear in mind that over-filling is as bad for your engine as under-filling; so don't treat the high level mark as a target. It's best to aim for a little below this line.

How often to check motorcycle engine oil? Our answer will always be to check it as often as possible.
