Completely agree with ZR. With a quality synthetic there is no need to dump it again in the spring. I do recommend taking your car out for at least an hour drive to recondition the oil in the spring.
I need some more info on your car, I will PM you.
Evenings and weekends are the best time for me. I can meet you whenever is good for you.
Normally I do 10% off MSRP for members to be competitive. This is a much better price.
