I purchased Genuine Toyota 0W-20 from two different online dealerships. One is labeled "Genuine" with PN: 00279-0WQTE (Ebay purchase 2017) and the other is not labeled "Genuine" with PN: 00279-0WQTE-6S (Ebay purchase 2018). Also, the latter product does not include a proper Mobil 1 date code. Mobil 1 and Toyota said to contact a Toyota dealership for confirmation. The online dealership claims the product to be genuine. The two products do smell different. Is this a genuine Mobil product? Are these the same product? Are any of you seeing the "non-genuine" bottles at dealerships?
