I live in Michigan & the winters are brutal here. I use all year around Castrol Edge Full Synthetic 5W-30. I change the oil every 3,000 miles or 3 months whichever comes first. Does not burn a drop.

No offense, but not burning oil really isn’t an indicator that the oil is doing it’s job

But, not burning any oil for a couple or few Kmi and beginning to with older oil is a sign that you oil IS breaking down. Course, if you change it before it breaks down, then you may well have more wise choices available for your application . . .and sure UOA is best . . .
