I plan on visting here until I figure out the best oil to use for my vehicles. I have the viscosity narrowed down to between a 0W30 and 20W50, or maybe straight 30W. I have the brands narrowed down to Amsoil, Mobil, RP, RL, Valvoline,Penzoil, Chevron, Shell, and a few others. Also, I am pretty sure I will either go with a dino or a synthetic.
