Re: Which Engine Oil?

I dropped the oil pan on my '50 custom 3 weeks ago, and cleaned it out (wasn't bad maybe an 1/8 inch of sludge). Checked out the engine block interior and although there was some dark discoloration over everything there was no heavy goo buildup anywhere at all. Since I'm trying to nail down hydraulic lifter noise, I re-filled the engine with 10-30w Shell Rotella and 8oz of Seafoam. I plan to put about 500 miles on the car with the 10-30w and additive to see if anything changes with the noise. I still think I have a worn hydraulic lifter and not a stuck one but this is just the first (relatively inexpensive) step. In the first 100 miles I haven't had any oil leaks using Shell Rotella. I ultimately plan to use Rotella 15-40w. Since I don't expect to burn up the interstates or put more than 1000 miles a year on the car, I'm not going to get too excited over the zinc issue (but that's just me).
