I wonder how much oil use varies with environmental factors?
My '12 RT is approaching the 6K oil change. Up to last week, it had used ~1/2 qt. since the 600 mi. check. One afternoon last week, I was 2-up in a long, hot DC traffic jam. Oil temp went up to ~3/4 of the display, but never reached the top of the range -- but I could certainly smell hot oil. By the time we got home (and after allowing the engine to drain on the sidestand, then putting it on the centerstand) the level had dropped to the bottom of the red ring in the sight glass. I put in .45L to bring it back to the top of the red ring. It stayed there through this weekend's 650 mi camping trip to the southern VA end of the Blue Ridge Parkway, during which the temps were on the 60's-70's.
