I use Mobil 1 in my 89 Convertible. 10W-30 since I live in the south and generally avoid those below 30 degree starts that require 5W-30.

No leaks anytime, anywhere. I suggest you search the posts here for this topic as it gets a lot of attention and posts. Good luck.

I also use MOBILE-1 10w-30 but any good synthetic (even some of the best non-synthetic mineral base oils) will work provided you keep the oil and filters changed and clean on a very regular basis and never let the oil levels get low. keeping the oil clean and filters clean is the key to good long parts life, as long as the oil is top quality

I use Amsoil but I have a relative who works for them so it kind of helps with the cost $free... I will swear by it though.
