What oil weight and brand are you guys using?

"More confusion occurs because people think in terms of the oil thinning when it gets hot. They think this thinning with heat is the problem with motor oil. Its more correct to think that oil thickens when it cools to room temperature and THIS is the problem. In fact this is the problem. It is said that 90 percent of engine wear occurs at startup. If we are interested in engine longevity then we should concentrate our attention at reducing engine wear at startup"

Exactly why it is useless and possibly harmful to run a heavy weight (0W) oil in a warm to hot climate like Texas. We will never see low enough temperatures to utilize the cold viscosity of the oil, so stick to a 5W or 10W is really all you need. But having a heavier hot viscosity is a good thing.
