For those that have asked about buying 0-40.
The Mobil1 web site has previously said that 0-40 is only available at BMW, and MB dealers.( There's a clue about who thinks this is the oil to use in high output motors) My local auto parts supplier went out of his way to obtain 0-40 from his warehouse for me. That was last year. He now stocks it on the shelf because the demand is there. You might ask your local guy. In addition, Auto Zone stores in the NY metro area have begun stocking 0-40 just this past month.
If you want to "save a buck" you might email Wal Mart from their site contact point and request that they begin stocking 0-40 in 5 quart jugs. That would bring the price down to $3.58 per quart. They were pretty responsive in stocking Mobil 1, 0-30 shortly after Mobil brought that out.
