use 5-20 or the MDS will not work like intended and you will get mis-fire codes.

Change it 3-5000 miles depending on how you drive and it will live a long happy life. An extended oil change is marketing BS to make consumer reports happy about lower maintenance. The really long oil change interval is for people who pretty much drive OTR highway miles with no cold starts or city driving idling... Also when you get a proper oil change it gives you a chance to get under there and look for other issues, fill the windshield fluid, belts..
