I'm going to just get my oil changed at the dealer with some more dino oil before switching to synthetic in a while (I'm close to 7500). I also need to get my tires rotated at this point (right?), so I was wondering if it would be a mistake to get the dealership to just do it, or if I should go to a dedicated wheel and tire shop for that. I'm in PDX if that helps. What do you guys think?
