Mobil 1
Personally, I'll go with Mobil 1 as I can get it locally and have used it before. Cars definitely start easier in the winter with synthetic oils. It is noticeable at how easy they roll over at -20F. If it's good enough for GM, it's definitely good enough for me. However, it wouldn't bother me to use a decent conventional oil with a bottle of EOS as I have have always done in our old L78 Chevelle.
