What does it mean when you get oil in your air filter?

How does oil get out of Honda air box?

What causes excess oil to reach the air box?
If it is too low it could cause excess oil to reach the air box during acceleration. Check to make sure it is properly routed and is not bent or crimped. If there is a tight bend in it, the engine will be able to force oil into it when you accelerate but the oil will not be able to drain back into the engine when you decelerate.

What should I do if my engine oil keeps blowing into the air filter?
Purchase an engine flush formula from your local parts store and follow the directions. In general you will pour the formula into the oil and run the engine for a period of time.
