Hello It would be really great if Migros would offer 20w50 motor oil for vehicles at their DO IT stores. My father said that they used to be available everywhere and nowadays you have to pre-order it either online or from special stores and can only pick it up in the store a few days later. I know older models have largely disappeared from the streets but they are not completely gone. I have tried 15w40 and realized that I am dependent on 20w50. There are about 3-4 types of 0w30, 10w40 and 15w40 from different manufacturers, so 20w50 from at least one manufacturer (e.g. Miocar) would be really conceivable. mfg
