Just took my 2015 RTL to dealer for oil change, my oil, and recommended 9000 service. I was told that it was 4 hrs to do this. This seems excessive to me and I was just wondering if this is in line with others that have the 1330. I also need a new rear tire and was told that was 2 1/2 hrs to replace. Not complaining about tire life, 9700 miles, but again 2.5 hrs seems a lot. Just wanted to get your input about your experience with your dealership. Thx in advance for input.
