I pre-fill, but I like watching my oil pressure idiot light shut off a second sooner after a change. But that's about the only benefit. The downsides could be: making a mess, and sending unfiltered oil into your engine (we're filling the exit port of the filters).
My oil light never came on even after an oil change with a "dry" filter?
Hot oil moves fast.
I don't even think I have seen the light blip on, if I ever changed the oil COLD, actually... (I usually let it at least get warm, meaning, let it run as I jack up the car. A new habit I have gotten into.)
And not a very good one. Drive the car,get oil hot. Let it cool as you jack it up. Then change the oil.
Timing belt snap yet?
