Update to this thread.
It has been about 800 miles since the oil change with bulk Valvoline Premium Conventional 5w-30.
75% of those 800 miles has consisted of 70-75 mph driving, a portion of it on hilly terrain.
The oil is already 2/3 qt low. I have never seen such high oil consumption before. Then again, I usually don't put this many highway miles on the car either.
Usually most of the oil consumption starts after 3,000 miles on a fill. Not this time. It is burning just as much when the oil is new.
Thoughts?
