I need to do my annual oil change on my 02 Vette that I normally store over the winter. I store it because of salt on the road and also because the small garage it sits in is in the back yard and once the ground freezes I can't open the doors to get it out. The problem I am facing is that in order to change the oil I should drive the car. However, our weather has been full of snow and there doesn't appear to be any end in sight. The nights are very cold and I am no longer sure I can get it out of the garage. Looking for pros and cons of simply running the car in the garage to heat the oil and doing the change there, rather then actually driving the car to heat it up. The car does have an oil temperature readout, so I would know how hot the oil was during a change. Any tips or experiences appreciated. Oil has been in the car for a year and has about 6K miles on it right now and I would prefer to get rid of it prior to storage.
