I have the V6, so I need 5w-30 but I really wanted to try the 0w-30 Mobile 1 "Fuel Economy" since my commute is about 8 miles I'm hoping it helps. http://www.mobiloil.com/usa-english/...l_1_0w-30.aspx
I didn't find the 5w-30 (or 0w-30) in M1 at my local WM nor the 0w-40 for my wife's BMW in 5qt jugs. Oddly, I just checked the website and it says my local WM has the 5qt jug of 0w-30 in stock for $26.48 = $5.29/qt. I swear it wasn't in the store 2 weeks ago. Anyway, the Autozone deal works out to $4/qt so it is still a steal.
