Mine seemed to get dry pretty quick. Ive had them on trucks and quads before and didnt have to oil that often. I guess with sitting directly in the wind and sun its going to need it alot more often.
I have to do mine about every 1000 miles or so here in the Phoenix area. It is just very dusty here all the time and the sun either bleaches or somehow removes the oil from the filter. Always tell a difference on the exposed side. I figure too often is better than not often enough.
Here in the Chicago area I have had mine on for a year and a half and 5000 mile's I just checked it and it look's brand new and oiley but it is inclosed !
