OK, there's a good point. But not all element filters go up,
some go down. My MGA has an MGB 5-main engine in it (well,
at the moment it's not in it as the car is undergoing
restoration), and the filter goes down, so the oil stays in
even when you're changing it.
I've got the impression that not very many people take
advantage of the check valve style spin-on filters, however.
