1. Most diesels wear more slowly than gas engines. The fuel is a better
lubricant than gasoline is, and the combustion products are a bit more
benign.

Except, of course, for the particulates. Particulates are hell on bearings,
and lungs, and...
NOx tends to run higher and isn't usually clasified as "benign"

5. Automatic mixture control.

"mixture control is irrelevent" would be a more accurate statement.

7. Lower fire risks.

Not really.

10. Props are more efficient at lower RPMs, usually. Diesels have torque
to turn props slow in cruise, like a turboprop (1800-1900 RPM), giving
maybe another 5% efficiency gain, and a quieter cabin to boot.

Depends on how the engine was designed, not how the fuel is ignited.


Given time, I can think of more. Please note that gas engines were
abandoned decades, nay, scores of years ago in other transportation
sectors. It will be the same in aviation if the weight difference shrinks
enough.


Well, there's the problem, isn't it. Making a light weight diesel that will
last.

Note: I'm not suggesting that diesels are a bad idea - they do have there
advantages. But, let's not over sell...
