I looked for it when Advance had the clearance of the 10w40 a month or so ago..no joy. It was like $5 a gallon.
 
The regular 10w30 Pennz conventional looked impressive at PQIA also. I use that stuff in my 2006 Cadillac CTS 3.6 even though GM recommends Mobil 1 5w30. Engine is still in top form and car is in great shape. Will keep it around for a lot longer.
