Just making everyone aware of my experience at my dealership with dropping it off for it's 500 mile service. I asked what was involved and included in the list was inspect the final drive fluid level. That seemed strange to me so I asked "Don't you mean replace?" and he said no. So when I got home I looked it up and sure enough it's replace not inspect. So Tuesday when they open I'm going to call and make sure it's replaced. It could be just the the motor oil used for break in, which they replace a semi-synthetic oil with a synthetic one. Maybe they are replacing the final drive oil with a different weight used for break in vs the rest of its life.
Either way make sure your final drive fluid is replaced at the 500 mile mark.
