I'm a super huge fan of Rotella synthetic 5w-40. But for the past month they have not been restocking it at my local walmart. No quarts no gallons nothing. Where else can I go to purchase this oil? Pep Boys and Auto Zone don't have it either. I'm in the Los Angeles area by the way so it is entirely possible that here in Commiefornia it's been made illegal because it's good stuff. But seriously where else, we don't have truck stops here either so no to that. Oh yeah I'm new so don't know how this works. But as an oil forum I'm hoping the subject of motor oil does not cause a flame war here.
