Hi I just visited the local Wally today, and to my surprise, had 3 qts of M1 5w-30 with the Starburst and donut on the bottle. Out of 7 qts of M1 5w-30 total, the non "suitable for..." accounted for 3 of the 7, so I bought them. There were about 6 5qt 5w-30 jugs which were the "suitable for.." . Here is the Mobil codes: 2 @ X17H5 5371S 1 @ X16G5 5371C Are any of these post-Katrina ? BTW, Havoline 5w-30 is now sold out again after flourishing for about 3 days of plenty. There has been no M7500 5w/10w-30 for months at most walmarts here.
