All the oils mentioned are fine to use as they contain sufficient zinc and your cars are happy. For the engineering types among us is the attached article about oil for vintage Corvettes (whose needs are no different than our Hemi, B & RB mills.)

My family has always run Pennzoil in all our old cars but it gets old buying it in cases of 6 quarts if I need to do multiple oil changes. I was considering Rotella T1 as it seems you can buy it in gallon jugs at least. Does anyone have any advice?
