My point......there is only one way to shut down a diesel.  Turn the fuel off.  Well I guess if you had a sleeping bag laying around you could stuff it into the intake.  Doing so in flight might be a little tricky. <grin>

Craig,

 

Typically, a diesel engine is equipped with an emergency shut down that closes a butterfly valve in the intake and is quite effective at shutting the engine down. This is an important feature as any source of oil like fuel introduced into the cylinder can result in a runaway condition.

 

As for oil life, most of the cars sold in Briton today use diesel engines and they seem to live quite well with similar oil change intervals as used on spark engines in the US. Oh and by the way George, the radiators on those cars aren't noticeably larger than comparable cars in the US.
