Does anyone happen to know whether if I can fully evacuate the oil sump on a QP via the dipstick tube? The dipstick enclosure is slightly different than what I've seen on other cars. It seems there is a thin metal tube inside a wider plastic based tube. The dipstick is put into the metal tube; but the dipstick handle/top covers the entire plastic tube. I assume I can replenish the oil directly into the general opening rather than trying to direct oil into the dipstick metal tube.
