A marine engine has the dipstick tube that goes to the bottom of the oil pan
so you can suck the oil out. The tube is actually longer than the stick.

An automotive disptick tube will only go into the block a couple of inches,
therefore you will not be able to suck the oil out in the conventional
manner. It will also not be bent the same as the marine version.

Correct me if I'm wrong, The dipstick tubes are usually the same, but
the stick is longer because marine engines commonly have deeper (cast
iron) oil pans. UD
