I was in Wally World and noticed a stack of Mobile 1 five qt jugs of super synthetic oil. It is labelled Mobile 1 Annual Protective synthetic 0-20 oil for those who want to extend oil change interval time.
Of course, the fine print said this oil is only to be used with the Mobile 1 special oil filter.
To you professional auto care persons, is there really an oil that can last for one year before changing?
