Is the Mobil 1™ sold in jugs at Wal-Mart the same quality as the product in quart bottles sold elsewhere?
“I have a question about the 5-quart Mobil 1™ motor oil jugs I buy at Wal-Mart. Is the oil in the 5-quart Mobil 1™ 5W-30 jugs the exact same oil that is in the 1-quart containers sold elsewhere? I ask because I have heard that Wal-Mart gets a cheaper formulation made to their specs in order to allow them to sell for less and you do not get the same quality of oil when you buy it. When I compared the labeling on the 1-quart containers at Advance Auto Parts to the 5-quart jug I got at Wal-Mart, I noticed that the 1-quart container says ACEA A1/A5 B1/B5 and the 5-quart does not say ACEA at all. Both have the HTO-06 and are, I believe, both API SN and ILSAC GF-5. Frankly, I doubt that any company would risk their reputation by packaging a different product for a chain store under the same name but I thought I would ask.”
