What make and weight oil do you use in a 350 mild build engine?

Fred

Weight depends upon your area / ambient temps. You would not use the same weight oil here in Phoenix as you would in Minneapolis.

Thanks for the replies. It looks like 10w 40 will work for me since the car is driven mostly in the summer.
Thanks,
Fred
