I agree with trav that a one size fits all oil really doesn't work because everyone drives differently under different weather conditions but one size fits most would possibly apply though.
I've been saying for days one size doesn't fit all. I'm glad I'm in good company. Honestly what harm [just for the sake of discussion because this horse was beaten to death] would there be giving a choice of a 20 grade oil for winter use, and a 30 grade oil for summer use? With a graph showing the temp ranges both grades would be good for?
