Mobil 1 15w-50 has been working fine for me in my '66 289, but I've only been using it for the last 10 years & 34,000 miles. No leaks & no measurable wear.
+1. I had a sticky lifter and Mobil 1 took care of it. Also it resists oxidizing and sludging when sitting in a warm moist environment (like Houston).
