Older Diesel engines used to rely a lot on the reaction of the sulphur content of the fuel with the nickel content of some alloys used in the manufacturing of the pumps and injectors. On a sidenote, as biodiesel is often pointed out as a lube too, maybe it would be interesting to try Castor-based 2-stroke oil often used in racing karts, which may blend well not only to regular Diesel but also to some higher content of biodiesel.
