You don't need any "fancy" oils. Even plain-Jane conventional oil will be fine. It's all SM-grade these days, which is light-years ahead of what your engine left the factory with 23 years ago.
The burning you noticed with Mobil 1 was likely the M1 de-sludging your engine a little bit. It has a tendency to do that the first use on old cars.
Castrol makes an decent oil, but they are the first to cheapen their products, then turn around to advertise how great their "invention" is. And Edge is over-priced compared to other common "synthetic" oils.
It's your money, do with it what you will.
