I was wondering what weight oil everyone was running in summer time? It doesn't really matter what brand just wondering what weight. I'm trying to decide what weight to use and just wanted to see what every one else was using.

People who know use Valvoline. :p

I usually use Valvoline 10W30 in the summer. No real reason. It just seems to be a good combination of price and quality. I have never owned a car since new, or even a fully rebuilt engine, so I haven't felt a strong need to go with a full synthetic. If I rebuild the entire engine, maybe I will switch over.
