I have a habit of doing this every 30 K on all my cars, less than 1 hour
on each. First I run the engine to get it warm, then pour in 1 quart of
flushing oil (kerosene) then drain, clean the pan, check the oil pump &
screen, replace the gasket, and yes there is always metal residue in the
bottom of the pan no matter how often you change the oil.
