Do you put oil in the new filter before install it

For vertical upside mount filter, you can and should add some oil before install it. My filters are horizontal mount so that it's make a mess if I add oil into the filter.
If the filter sits vertically, I try to prefill it. I know...
I've pre-filled both types of filters.
The horizontal ones just take more careful maneuvering.

Can't. They're both horizontal.
It's not as if we're starting an engine sans oil. The skim left from the old oil should be enough for a half-second (for most cars) while the new oil is passing through an empty filter.

Yep :^)
All the ones I service are horizontal. Dont know if I would bother even if it was vertical.
I just recently did it on my 1990 4Runner. The filter is mounted diagonally with the base facing down and I prefilled it enough so the oil wont spill out.
It's always beneficial to pre-fill the filter as much as practical.
Yes
It doesn't make a difference. Of course, it won't hurt anything but your engine is not going to get damaged if you don't.
Yes, I do, but my filter goes on horizontally, so It takes more effort to do, and I can't put as much in as I could on a vertical one. It certainly doesn't hurt.
I usually change mine when I start to notice the oil pressure light staying on at startup, I figure that the anti-drainback valve is getting tired. It's always nice to see the light go out right away again (barring the first start where it has to re-fill the system).

I prefill my filters, and have been doing so for years.

When I was working as an apprentice mechanic for a Chevy dealershipyears decades ago, we didn't pre-fill the oil filter canister before bolting it to the block. (The oil would have leaked out the bolt hole at the bottom until the bolt was snugged down!)
After the spin-on oil filter came out with the '68 model year cars, the collective wisdom became pre-fill the filter assembly before spinning the filter onto the engine block. Old habits never die, I still pre-fill my oil filter when changing oil on my SBC's.

I've never done it, never saw any advantage to it.
I do if it's easy. six one way, half dozen the other.
When I was working for a bridge construction company we always did it but some of those filters were H U G E and took a lot of oil. Same with fuel filters. That said I don't bother with my personal cars
