I've asked this question many times over the years and cannot seem to get a difinitive answer. Living in the northeast I, like many other Vette owners, put my car in hibernation at the first sign of snow. I also do not travel enough mileage to change my oil any more than once a year. So the question is am I better off changing my oil before the storage or in the Spring when it comes out of storage? I have a new 427 LS7 but I would imagine the answer would apply to all engines being stored?
