Would you change your oil after driving 70 miles without an air filter? A member of a different forum said he had an air filter on order and couldnt find one locally, so he was driving around without a filter on. I suggested he change his oil after the new filter shows up. He later mentioned that he has only drivin 70 miles without a filter. I dont know what the conditions were during the driving. Motor is a Dodge 2.4l turbocharged 4 cyl. a few of the other members are saying that I am to anal about it, and that driving without the filter is fine for that short of time. To me, 70 miles is a minimum of 1 hour of driving. Just curious on the consensus of this forum.
