I changed my oil in April and have only put about 350 miles on it and it is going into winter storage soon. I use Mobil1 15-50 and I usually change it to a mobil1 10-40 for the winter, but I also usually drive the car more then I did this year. What do you guys think should I change the oil now for the winter or leave it alone and change it when I bring it out for spring?
