CT5-V CT5 Blackwing oil change

[BigBrett]

Hello all, I see that Mobil 1 offers a 5w-50 dexo R oil for our LT4 was wondering if any of you in warmer climates use this?
It would be nice to have a little bit thicker hot film, especially when track days or even hot commutes
Thanks again

I hesitate to insert myself into an oil thread - ha! But I think the general consensus amongst the oil nerds is that th 5w50 is good for a short time - i.e. track use. But even in southern/summer temps the 0w40 is more appropriate for daily/road driving and/or trypical oil change intervals.
