Would it be a bad idea to drop the oil pan, clean it out, refill it, drain it, refill it again? Letting the car drive a few miles before the second drain an refill? I just feel like someone used a heavy weight oil in it and neglected changes every 3000 miles. I would like to get as much old oil and sediment as I can out.
Also in dropping the oil pan, with my vw I have to place the motor in the service position and a few other things, on this focus is it as easy as just dropping the pan?
