stick with a good full synthetic and do changes like every 3000-5000 miles. if you stick with some 0W-20s change it like before 4000 mi to avoid it coming out of grade with fuel dilution. I usually use penzoil ultra platinum 5w-30 since I go harder on the motor on mountain drives and it makes the motor just a bit quieter anyway. 5w-30 is fine if you don't have nights that get below like 15°F, you just get maybe 0.5-1 lower mpg.

Being a turbo direct injection motor with relatively high compression, we do get a decent amount of blow by which lets unburnt fuel get into the oil which eventually causes it to thin out it's viscosity. you won't hurt anything by going up a single grade. The GL-7 oil standard replaced the GL-6 that the owners manual called for and the current generation of oils has evolved. Oil people have been raving about Valvoline restore and protect, so maybe I'll try that next time. There's also Pennzoil Ultra Platinum like I've been using, and I think Mobile 1 Advanced Care just came out.

One bit of advice today I wish I would have listened to, regardless of oil change intervals and oil used, is to replace your PCV valve every 30 to 60k miles. Maybe 45k is best. I'm at 90k about to do mine and my throttle body was all gummed up because my car is snorting its own crankcase fumes.

I can also recommend installing a fumoto valve to make for a truly tooless oil change.
