engile oil, what do you run + additives

[dukcaln]

so I am about to change the oil in my motor and since it is the first or second change from the build( not sure what previous owner did) what do you all recommend for oil, weight to brand and do any of you guys run any additives and if so which ones and why... Since I didn't build or breakin the motor, I need to make a choice as to what to run in it...... so let me know what you run and why...... I come from a long line of diesel engines and a mild built v8 is new territory for me...

O, and how many quarts will a 350 hold with stock pan....
