I'm planning to make this switch. I know this topic has been discussed before in one form or the other, but I would like to have some more focused input - 10W30 vs 0W40. I use Mobil-1 and live on the Eastern shore of Maryland where the cold temperatures are usually quite mild. I don't plan to run during the winter. Thanks.
