Would this prevent a dry start?

Unlikely. An empty filter causes it so if its full you should be good. The only issue i see is if the filter runs out of used oil before new oil gets to it causing a brief delay in the oil circulation if you get what im saying.

Nope.
Unless the drain back valve has failed of course.
Otherwise the oil circuit from the filter forward still has oil and only the circuit from the pick up tube to the filter will be empty,which I suspect happens every time you shut off the engine.

I don't bother. I would rather not potentially compromise the gasket and the seal.
At most there is a quart in the filter and top end. At the most.
Considering most drain the oil way too early anyways that means there is still serviceable oil up top,and new oil in the pan.

I wont be taking off the filter for the oil change, what would be the point of taking off the filter if you are re-using it. Might as well change it if its off =P

I feel like Clevy that I would rather not affect gasket and seal while pulling off filter, draining, and reinstall. When I do reuse a filter for a second run, I just change oil, and refill.
And I don't think you ever really get a dry start as there is oil in the top of engine and still in oil rings from previous shut off. However you do want to get the oil flowing as soon as possible.

Exactly! Thank you for pointing this out.
I think a lot of peope should repeat this a thousand times and maybe then we would have a lot less silly questions/opinions about dry starts.
