Very nice car! And
to Packard Info!
As for your questions:
1) I run regular gas with about 3-5% diesel. I find the diesel helps with these older engines, particularly when running with a DL 51 updraft carb.
2) Quite a few of us run Shell Rotella 15W-40. Straight 30W will also work. I am not sure, on these roller tappet engines, if adding ZDDP is helpful, but it won't hurt. Unless you know the oil pan is clean, I would highly recommend dropping the oil pan and cleaning it, and the oil distribution tubes to the main bearings. I would also strongly recommend flushing the radiator and cooling system.
3) You can buy an L-2 reproduction oil filter that takes a modern spin-on filter (which is housed inside). I know the major vendors, like Kanter and Max Merritt, carry them.
4) John Ulrich has tail-light stanchions. His info is
here.
Cheers,
Tom
