Not being a smart a$$ here but.......
I just picked up a 5qt Jug at Walmart of the "New" Castrol Edge 0W-40.
(European Formula)
Made in Germany, Meets BMW Longlife-01 for $25.17.
The German Castrol used to be 0w-30.(i have used it the past 14yrs on 3 type of vehicles with great results, the best oil IMHO)
Not sure if they have 2 flavors of this German stuff or they are doing away with the 0w-30 and making it 0w40 in order to compete with Mobil 1s 0w-40 Euro formula.....
