Eric, heed Wat. Why are you running molasses in your engine? A friend w/ a 292-ci Zephyr V-12, which of course has hydraulic lifters, decried their noise.
I talked w/ a pair of lifelong Zephyr guys who on hearing his lament, shared the same first question and suggestion: "Why is he running glue (or less polite) in his engine? Tell him to change to 10W/30, add a pint of Marvel Mystery Oil, then drive the hell out of it for 30-50 miles."

Meanwhile, at the risk of sounding like a broken record, enter zinc/ZDDP in the Search box here. Short story: The ZDDP scare was just that, but marketing abhors a vacuum. Just use any major brand 10W/30 and don't reinvent the wheel.

Packard service departments coined a good expression: "Factory standard."

50W oil is hardly factory standard. And really, avoid any product called "Classic."
