I switched lot from Valvoline, Mobil 1, and a few others when I realized the supertech full syn was quite a bit cheaper. I looked at the SAE rating, and its actually better than some of the brand names. It says its SAE rated SN oil (higher S grade, better oil), and teh valvoline and mobil 1 is only SM. Not a big difference in quality, but still. Less expensive, and one grade higher. Any thoughts?
