Just curious if anyone elses Walmart is low on Mobil selection? I went last week one day and I seen that they had the 5000 and 7500 in boxes ready to be put on the shelves....I went back Saturday night to get oil for my GF's car and they had no Mobil DC in 5w30...any the 5000 and 7000 wasnt on the shelf. I went back on Tuesday and the 5000 and 7500 was on the shelf, but neither were available in 5w30. Strange...also no Mobil 1 in 5w20(0w20) or the new formulas either. Just throwing that out there.
