A couple questions.
Its been a while since Ive even needed to look at oil (private stash is dwindling
). My truck is not driven much, maybe 6K miles per year. 99% of the time is short trips, so Ive always been using full synth, but not necessarily a boutique synth (like RL). Currently running Shell Rotella Gas Truck 5W-30...the engine seems to like it, its a bit loud but not nearly as bad as PUP 5W-30 was.
Rotella GT seems to have disappeared from my area, no idea why. Because of that, what would a decent off-the-shelf oil be? I saw Castrol (gold bottle) mentioned...*that* I can get, along with pretty much any variety of Mobil 1. Not averse to changing viscosity, within reason.
Second question - I had 2 RP filters hanging around in my oil cabinet. Checked them just to check them and noticed there is a bit of rust at the "seam" of the top of the can (thread end). Pics attached. Also note, one has flat holes and the other has "scalloped" holes. These have been sitting in my cabinet for a bit, but curious if they are still usable.
Thanks in advance.
