I lived in Lindenhurst IL (west of Waukegan) when I had my bought new 95 JGC 4.0. I ran Mobil 1 10w30 for the 176,000 miles I owned it and my son-in-law now has 198,000 on it. Fram oil filter. Never a valve cover off or any problems except rear main seal replaces at 102,000 miles. With the new 5w40? SUV/truck oil out I'd probably use that.

I have used GC, AFL, ATM, T&SUV, and Pennsoil in the past. 12.5k miles on the T&SUV with a long commute. I recently got a job 1.5 miles from home, and I'm actually going to be moving closer this summer, I still don't know what I'll do. Probably RTS at 3k OCIs year round. GC is in it currently with a purolator Pure-One filter.
