I have not yet changed the oil in my new 370Z (still under 400 miles and one month). The oil in it at delivery is, I understand, an ester based synthetic. If that is correct, wouldn't it be unwise to replace it with dino oil for the first change or two as some have recommended, because the car has been run for 2 or 3 thousand miles on ester based synthetic? Bottom line: Is the oil at delivery ester based synthetic and if so does that mitigate against a dino oil replacement or two on the way to permanent use of synthetic oils, thereafter?
