okay, I'm game, but help me understand something first...
Why would I want to run a thinner weight oil down in south texas? I have two friends that work at Southwest Research Institute and I've seen actual specs on the different oils/weights. Bottom line is the mobil 1 15w-50 is hands down better in the specs than the lower weight Mobil 1's. BTW, i know amsoil is better, but I can't afford it!
So why would I want to run a lower weight oil?
