Hi, I was quoted by my dealer up here in Canada that its going to cost 850 dollars to winterize oil and tranny oil change. This sounds high!!! Wondering what others r paying, and also, if I have to go through my dealer. Another dealer said 550. And an ex dealer I know said he would do it for 400. But to keep my warranty, should I just go through my MC dealer and pay the 850?? Your thoughts are appreciated.
