What aftermarket oil would you recommend for the 6.0/6.4 diesel? the reason I'm asking is that we're having and been having a rash of injector failures on the oil pressure side. No pintle/diesel fuel issues at all. We're using Delo 400 and I'm thinking on using a more detergent based oil. any recommendations?"
