:rolleyes: What is the best oil to use on my E40D 1991(7,3l)? Temperatures from -10 to +30 Celsius?

I would say https://www.amsoil.com/storefront/atf.aspx

I would say amsoil 10 40 to be the best, but if you dont have the cash go rotella t 10 40 it works well I know this because I live in a pretty cold region on the northern most shores of lake Michigan in Escanaba Michigan.:cool:
