1 Where is the oil going?
I just had the oil changed, I have no apparent leaks in my 2009 Sierra. I placed about 2500 miles on since the change -noticed the truck running rough and oil pressure guage dropped-pulled the stick and it is low with just a little oil on the bottom. Where is this oil going -using synthetic and changing at recommended intervals.
