You can run an M1 all day long on the worst diesel out there with no additional maintenance issues. I’ve done it.
Now don’t be interjecting real world experience here...:) The ‘Net knows all...:)
Well, I have never burned out a jet engine, and I fly aircraft, not tanks, so I will defer to you on this.
What I know is that if you start using different grades of fuel, you effect the temperature and the friction on the bearings and blades. I turbine engine, with compressor turning at about 30,000 rpm has a very tight tolerance on the blade clearance with the hot section housing. Blades grow and shrink in length as the temp goes up and down. To much and things fly apart inside the engine catastrophically.
Another disadvantage with diesel is that at low temperatures it may freeze or form wax crystals blocking filters and stalling engines. This is a problem given aviators fly at altitude under bitterly cold conditions. Jet fuel is manufactured to keep flowing under these circumstances. It can also act as a coolant for the engine oil and maintain clean injector nozzles, avoiding carbon deposits in the severe temperature regime of modern turbine engine design.
Now maybe they build these tank engines at reduced efficiency so there is more tolerance in blade creep. In aircraft, the efficiency is kept high by having tight tolerances, and using the right fuels to keep temps where they need to be.
