thanks to DIY Dave I saw his video on his Toyota Corolla burning oil and he did the Berryman B12 chem tools upper cylinder cleaning overnight and it helped him. I did this as well and it worked. this is a common problem with GDI engines and some others. I commonly do my oil changes 5000 miles and I'm all highway but they still happen.
