Been running Valvoline Full-Syn 5W30 w/mopar filter for a while now. Change approx. every 5k. Gonna try Royal Purple next, My local Wal-Mart just started stocking it. Lil expensive though.
Currently Mobile 1, 10W-30. I tow a trailer daily, so I went from 5W-30 to the 10W-30. Filter is made by Champ labs. As long as it is not made by Honeywell, (Fram) or made overseas, I'll use it.
