How often do I change oil in dirt bikes?

It depends on the type of dirt bike you have and how often you use it. In general, you should change the oil in your dirt bike every 5-10 hours of use. If you use your dirt bike more frequently, you may need to change the oil more often.

Here are some signs that it's time to change the oil in your dirt bike:

* The oil is discoloured or has a milky appearance.

* The oil smells burnt or rancid.

* The oil level is low.

* The dirt bike is making a loud or unusual noise.

* The dirt bike is losing power.

IIf you have any doubts about whether or not it's time to change the oil in your dirt bike, I recommend always opting to perform an oil change as regular oil changes can also keep dirt, metal shavings, water and sludge from making their way in your engine while reducing wear.
