If you fill the filter with oil before screwing it on, you won't have to add,
later. I've found that you can get a *lot* of oil into a DRY filter -- even
if the filter is mounted "opening down" (e.g., like on Subaru's). The
filter pleats capture and hold the oil (even if you can't *completely* fill
the filter due to risk of it running out while you are screwing it on.
"Wetting" the O-ring on the filter with a bit of fresh oil also helps
improve the seal to the block.


Been doing this since I was a teen. Filling the filter gets oil to
the crank bearings much faster. Good idea on older high mileage
engines. Rubbing oil on the filter O-ring also prevents the
possibility of the rubber binding and perhaps not sealing.
