So we maintain a 2012 Mercedes-Benz Sprinter 2500 and we want to use a 0w-40 oil also with the 25k mile protection. Seems Amsoil doesn't have an option for us that meets the MB 229.52 spec. BUT, if this vehicle has had the particulate filter removed and the DEF system deleted, then does it need to meet that spec? I see either product DZFQT-EA or AZFQT-EA could work (both 0w-40 oils), but they don't mention if they meet the MB spec or not. Product EFOQT-EA says it meets MB spec, but it's not 25k mile oil.
