Valvoline VR-1 for me. Available at Napa. The weight depends on where you live in the world. For me as far South as I live, 30 wt. pretty much year round in the big blocks. I use Castrol 10-40 if I can get it at wally world for the daily drivers. If not, 10-30. droldsmorland pretty much called it. There are a thousand threads on the subject.
