Hey, guys. I know, I'm sure I am beating a dead horse and it's inevitable I'm going to annoy some people with this question. For years, I have prefilled (as much as I can) the oil filter on my F-150, in an effort to help the engine receive oil flow to the bearings, as soon as possible. I'm getting ready soon to do the first DIY oil change on my 2007 Mercury Grand Marquis that I recently purchased and I'd like to hear your opinions on prefilling the oil filter before installation.
Being that the Modular engines in light duty Ford F-Series pickups and Ford Panther Platform cars have horizontally mounted filter angles, it somewhat makes it a bit more challenging to prefill the filter, without spilling, which pretty much limits me to only a halfway prefilled filter, at best.
So, now to the point: Being that the filter these engines take only holds about maybe 1/2 - 3/4 of a quart of oil (if it is completely filled to the top), is there really any scientific advantage to prefilling the filters before installation, or is it negligible? I've been on the fence on this topic for a long time now and I've never actually asked anyone else for their opinion on this topic. Just always used this method, based on my own assumptions. Thanks!
You can, but I doubt your car will care. I'd guess a majority of people don't and their engines last a long time. I never have.
