Op wants 0-20. Which Mobile one for $28 meets that? Your statement was that M1 is $28 at walmart and FCP Euro is inferior oil. My response I'm running Redline 5w30 which is $147.11 with my filter and I can get it for $18.00. I'd call M1 the inferior product between the two.Not VW 508 though is it? OP wants VW 508.
