Absolutely no damage. If it has the proper oil and coolant. Systems working OK. Michigan people start em up at down to -20 degreesF and drive them to work quite often. During the winter season.
We don't know the present miles. But, these motors, un abused, with proper maintainence, go well into the 2 hundred thou figures.
How many miles on this 1/2 quart of oil usage? Older cars will use some oil. Abused ones use more.
