been circulating through your engine all the time it has been
running presumably not doing any harm. With fresh oil in the
crankcase you won't know it is there. </p><p>The only exception might be if the oil has been contaminated in
which case the best thing would be to remove it and the hoses and
flush them. You would have to do that with the engine anyway.</p><p>PaulH.<br>
