If everybody just went by the owner's manual and had no doubts about its oil viscosity recommendation, we'd have nothing to talk about here on this board.
This is actually a very good point. The only reason I posed this question is because by my very actions I'm knowingly going against what the manufacturer has recommended. That said, we get right back to the whole "OW-XX weights only exist for the manufactures to satisfy CAFE" thing. I've heard enough negative comments by knowledgeable people to have reasonable doubts about the effectiveness of these "high mileage" grades. I'm sure GM or Ford or whoever is more concerned about hitting their CAFE goals than they are about whether Joe Blow's Sierra lasts him 10 years vs 15 or 20.
I for one am very grateful to be a part of discussions like this with people who may know far more than I do about this. I think all the comments here have validity. At least for me anyway. It's nice to hear what someone in California thinks about these grades as opposed to just Texas or Louisiana folks. I am def learning a lot here which is why I joined.
