My dealer stated that the 7500 mile interval does not apply since they consider use in New England as severe duty. Hence the 3750 interval recommended to me. Generally, severe duty is warranted if the vehicle is used in lots of stop and go driving.
Unless you are a travelling salesman, I'd stick with the 3750 recommendation, at least until after you've switched over to synthetic (if that's your plan).
