I'm just curious how many miles people change their paper filter at if they're using a regular filter (NOT oiled!!!!!). I check mine about every 5k miles and change it every 10-15k. Yes, I know that's not really necessary but for a $10 part that is critical to engine performance, I'll spend a few extra bucks! And do you use the stock filter or STP or what brand? I use the STP.
For the poll, pick the mileage that's closest to your change interval.
