I agree strongly.
Get some used oil analysis done and see what works for your vehicle, but I've seen it so many times that spending the $$$ on synthetic motor oils isn't cost effective, unless you are going for extended drains.
A run of the mill chevy motor will live a happy life with any API SM motor oil. Buy whats on sale.
If you had a turbocharged/supercharged/high performance application, then my tune would change a bit.

Otherwise you can just go with the Mobil clean 5000 in 10w30 and change it at 5k and you'll be just fine, IMHO. 10w30 SM rated oil is pretty tough stuff.
