I know theres no definitive answer and it will come down to personal choice, but does anybody pre-fill new oil filters with oil when changing them?
I'm asking because I'm building an engine up on a stand and it might not go back in for another 6 months. I'll obviously fill the sump when it goes back in, but am just wondering if it would be a good idea to fill the filter.

Never have done. If i’m Starting a car that’s had any engine work done apart from an oil change i disconnect the injectors and crank for ten seconds to build oil pressure. No problems yet

For filters that wont leak everywhere if they have some oil in them, yes i pour in some oil before fitting. I'm not a fan of sitting and waiting for the oil light to go out after a change, and filling it speeds that up. I don't think it makes that much of a difference though.

if its not going to be run there's no point, hopefully you will have used assembly lube on the bearings rather than straight oil.

Why not? I always fill them if I can. Makes sense, the more oil in the lines the quicker you will get pressure and less hassle you will have if it doesn't prime too easily.

i always pre fill the filter when its possible, mainly because i love the oil dripping on my face when on my back trying to get the bloody thing back on before all the oil drips back out of it.not sure if it makes a difference but have always done it

Where possible I pre-fil the filter. Does it make much difference? Probably not.

I always prefill, no matter if it's getting used immediately or left for months.
For starting a rebuilt engine, I take the sparkplugs out (to redurce stress) and turn over with short bursts on the starter motor until the oil light goes out.
I expect it would be ok without but I do it out of mechanical sympathy (and force of habit).

Always fill if its not an upside down filter then crank with HT lead removed for a few seconds to build pressure.

As others have said do it if possible. I always do and remember that if you don’t on some cars like the scooby flat 4 you can run the bearings!

I only do it if the filter mounts vertically and I'm not going to get covered in oil. The pump will always have a good amount of oil in it anyway.

I always do it. Surprising how much oil it takes, which has got to come from somewhere. If you put it on dry, then crank the motor, it'll fill the filter, but that means there's less in the sump, which means having to put more in the motor anyway...
Unless the filter is mounted horizontally, why wouldn't you?

Even half full is better than dry - you'd be surprised how much oil you can get soaked into the element itself which won't come out (easily) and every little helps. If you're quick, you can keep a lot in there and if you spin it on quick enough, centrifugal force helps keep it in  |
