I recently brought my G35 crosscountry from LA to Boston. As the temperatures are beginning to drop, I was wondering if I have to add any fluids to the car that the dealership might not have provided in LA, since the temperatures almost never drop below freezing. thanks in advance!

 

Shouldn't have too, but if you have any doubts about your antifreeze, buy a cheap tester from autozone or similiar and see where it falls for temp rating. You'd hate to have a high water content in a freezing climate but there shouldn't be any difference between LA and Boston for service. Except the price maybe.
