33k, going in in the next couple weeks for oil change #4. That's moderate driving (half highway, half in town). What amazes me even more is that at least 5k of that is full off-road, usually gravel lots of dust, etc. and the air cleaner is still clean-as-new. I remember having to change air cleaners all the time on dusty roads back in the day of carbs and open air cleaners. I love technology...
