Are you SURE?!?
Remember, 5W-20 was coming on the scene (Honda and Ford) right about this time 16 years ago, and I think it was SL or SM. Hardly what I would call "not as stout".
I would run 5W-30 in this car in weather far, far, far warmer than 50*F and I wouldn't be worried even 1 iota.
I'm surprised they allowed 20W-50 to even exist on this chart.
16 years ago, 5w-30s would shear down to 5w-20s pretty quickly. 10w-30s would stay a 30 grade.
That's not the case so much now.
Yes linctex, I am sure.
