what weight oil are you running??

**freeline95** · 07-30-2009, 02:24 AM

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.

20w50 Valvoline has been my choice in almost all my cars.

thanks for the reply. I also forgot to mention that this was for a 3.8 SC.
