    what weight oil are you running??

    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.

    Royal Purple 5w30 synthetic has been a good performer for my mostly stock 3.8L SC

    I use 10w40 Royal Purple in the summer. If I ever raced I would try 5w50.
