Good thread! How much 2-stroke oil per litre of diesel, Skippo? Must admit if Cummins don't recommend 5% oil mix, i would run with 10%.
I've happily run a diesel car on cheap engine oil before (during the last uk fuel crisis), but you have to make sure it is clean. The temptation is always to put the sump oil in the tank, but those carbon particulates would detroy the pump in about 10'000 miles.
SaSless, i would be mildly concerned about the injectors with Jet A1, even if the fuel pump was eng lubed. Without additional oil they would not last as long between overhauls - last time i looked it was only ~£100 for a set of four Lucas injectors.
I would also be extremely wary of water contamination, this will cause extreme pump wear whether or not you add oil.
