2009 LT, 3100 miles, My wife and I are leaving on a 7 day trip and will cover about 2000 miles, so 2 up and fully loaded, highway speed. How much oil should I expect to consume? I packed a quart and a funnel....too much? Previous to the LT I was a RT guy. I have put about 500 miles on this LT and the oil level has stayed mid sight glass.
