I have forgetten the exact specifics, but for an oil to have a certain S rating, by definition it has an equivelant C rating, even though it is not marked that way on the container. For example (again, I am going off dim recollection so this may not be exactly correct) for example, say an oil had an SF rating a few years ago. The mil-spec that is equivelant to SF also has a spec which is equivelant to say, CC or CD. Therefore by extension, there is virtualy no motor oil (except for non-detergent of course) which you can purchase in North America which is unsuitable for use in light duty diesel engines. Please note that I am not suggesting that you run some generic 10w40 in your brand new diesel, I am just stating that any oil rated higher than about SF or so is suitable for light duty diesel applications, even though it may not necessarily be the best choice for such applications. This info can be found in an old Frank King article in MBCA STAR Magazine from about the mid to late 80's if somebody would want to take the time to locate it.
