Good choices!! The Mobil 1 is a synthetic filter, meaning it may filter out smaller particles.
Did you say you were pulling the pan off?? If so, then while it is off, thoroughly clean the pickup screen! See old posts about some of the potential disasters lurking there (mine being one). Better yet, think about a new oil pump.
The pan is a little challenging to remove. You have to unbolt the 2 engine mounts and then jack the motor (or lift) up a tad. You may have to also rotate the crank by hand to get the counterweights out of the way. But if the pickup screen is clogged, you have done yourself a great service. If not, you still have piece of mind.
