Is 20W-50 too heavy for my 340?

Ive been using Brad Penn (Penn Grade HP Oil) 20W-50 synthetic blend in my 3 cars for years now. No complaints.

I currently run Brad Penn 30wt in my 360 dart sport. Works great. I recently purchased schaeffers 30wt. Have heard good things about this oil. What do you all think?
