If I have an engine that allows for filling the filter beforehand I do so . But either way I always make sure my oil is warm and well circulated before doing a change . That way I'm fairly sure there's at least a coating of oil before restarting the engine . On my 6.0 deisel the filter is on top of the block . there's no way to pre fill it . But it fires right up after an oil change . As the injectors are run by engine oil , there must not be too much air in the oil system . John
