of course I know that you are aware of the differences... I was only mentioning it for the benefit of other readers. Anyway, the 45k mile service hasn't been done yet, but it includes new filters and fluids all around, the coolant system and brakes get flushed and inspected, with the new fluids come additives to recondition seals, and they clean, inspect, and test every mechanical part on the car, replacing or repairing as necessary. Since Acura cars come with a 4-year, 50k mile warranty, this is a good opportunity to have it gone over by the dealership, rather than waiting to notice or find something on your own. If I had my owner's manual handy, I'd list out everything individually, but I think you get the idea.
