I usually look to see which ever big brand (Delo, Rotella, Delvac) is on sale and grab that. You can easily do 5k oil changes on modern dinos, unless you're doing something in extremely dusty conditions or racing.
Unless something is wrong you should have NO trouble getting 5k miles out of a good name brand oil.
I run whatever brand name 15w-40 is on sale at wally world in the summer and rotella t5 10w-30 in the winter. For the change I am currently on I have the donaldson elf7405 oil filter and might try to stretch the OCI out to 7500 miles or so. We will see what the UOA says, I am pretty confident I should have no trouble getting that.
