This argument is going around, but I wanted to make it clearer. We need a better consensus on the best oil to use for High vs. Low milages and Cold vs. Hot tepmeratures. It sounds to me like Castrol or GTX are everyone's favorites. I've been using Valvoline for the entire life of my car, and it's been fine, although it does seem to get dirty fast.

In general, you best conventional oil is Castrol GTX and the good synthetics to look at are Amsoil, Mobil 1 and Redline.
