Technically you shouldn’t pre fill filters unless the car has sat for along time. And if you do prefill filters you defiantly shouldn’t pour it in the big hole. You should slowly pour it into the side smaller holes and let it slowly filter through the material otherwise if you get shit in the big hole it will be going straight to your journal bearings.
The odds anything bad happens is super small if you are clean but better to be safe that sorry especially considering there’s enough residual oil in the engine that the 2 seconds at the absolute most it takes to fill the filter won’t be an issue.
But this is as far as I understand atleast. If a mechanic knows more please correct me but this is what I’ve always heard/done.
