I was excited to hear that Walmart is stocking Motorcraft oil and filters again. It is the most convenient and cheapest place for me to source these oils and filters. I stopped in my local Wallyworld today and I was dissappointed to see that there wasn't any Motorcraft on the shelf. I was just about to leave and at the end of the isle against the wall where they put the overstock stuff they had about a dozen cases of Motorcraft oil and unopened boxes of filters. I scored two cases of 5W30, one case of 15W40 and an unopened case of 12 FL820S filters. I wonder what the real reason Walmart stopped carrying Motorcraft stuff (like they did with Chevron a while back but that has been brought back too). The Motorcraft seems to be a favorite as the oil and filters both move quickly.
