Does a cheaper source exist? Everybody says that they have found it at "Wallyworld" in the 5 qt jugs... Is wallyworld, Walmart? If so, here in Detroit, I have never seen Mobil 1 0W40. I actually called Mobil and asked them and they said that they only offer the 0W40 synthetic in the 55 Gal drums or 1 qt jugs.

Does anybody have a good source for this oil? I now have 2 cars that specify Mobil 1 0W40!! 13 QTS every 2 months is going to suck!!

The stealership actually quoted me $115 for an oil change for my SRT8!
