Synthetic 5w50 Schaefer oil

Hoping to hear back from her Monday or Tuesday. I'll post whatever she comes back with
if she`s beautiful, post a pic of her ! Back to the oil. When we ran the hemi for 14 yrs., we used who ever would furnish oil for us, didn`t seem to make a tinkers dam what brand, always ran 40 or 50 weight, course the hemi`s were set up loose back then.
