I've used Mobil 1 in an older model Thunderbird with no problems. It didn't leak a drop when my wife wrecked it.(totaled) I run Shell Rotella T in everything. I use Lucas Oil Treatment in my '89 B2 only because it has 209,000 + miles on it and ticks like a thrashing machine without the additive. They're all good, I think it's just a matter of preference. :xyxthumbs:
