Well just picked up two cases (12 quarts) of 5W-20 all with the code of HLPA305778 04085/00:58. Some are one minute before, and some are one minute after 00:58. So, I'm thinking that these 12 quarts are before the Group III switchover.
Oh, BTW, got it at the Orlando Navy Exchange or $3.00 per quart. When I went in, they did not have any, even though it was in their newsletter as being on sale, 2 for $6.00. I inquired and the guy who stocks the shelf said that they had not received their shipment, so that was it. I then found one case stashed on the floor, not in its normal place. While shopping in another department, the guy I spoke with, found me and said that he found another case in the back and do I want it. Said yes, so I got all 12 quarts they had.
