FYI, for anyone interested....
In my location, Northern Virginia [Western Fairfax], I bought the last three quarts of Mobil 1 EP 5W-30 from the Advance Auto parts in Herndon. I also checked Wal-Mart, K-Mart, Fairfax Auto Parts (in Chantilly), and Walmart (in Fair Lakes). All were completely out of Mobil 1 EP 5W-30. I did find plenty of Mobil 1 EP 10W-30, but no one has EP 5W-30. I also noticed the "suitable for" label on the regular Mobil 1 5W-30.....
For some reason, 5W-30 EP is hard to find....
