not sure if there is a filter section to this forum or not but..
the fram ultra says you it lasts up to 15k miles... so does that mean you use the same oil for 15k? or do you need to change it 2-3 times but just use the same filter... and if you do use the same filter do you still need to remove the filter and empty it or do you leave it on and just drain and refill the oil?
and does it last 15k with conventional oil or only synthetic?
