..conservative, these ain't exactly aircraft engines with zero tolerance
on accidental shutdowns, they have TBOH in that range.  
Picture automobile cruising, but 'till it stops, could easily take
years,  avoiding the usual 3 cold starts a day, cuts wear by half. 
Numbers I've seen is 500 to 800km (300 to 500miles)  worth 
of wear per cold start, times 3 coldstarts matches 1500 to 2400km 
(or 900 to 1500 miles) per day.  These engines easily lasts 500 000km 
to 1.5 mill km before scrapping, with those 3 cold starts a day, so you
_can_ expect a car engine to last 1 to 3  mill km or 10 to 30 000hours,
at _cruising_ loads.  
Note that they are usually rated at maximum HP's, and not the 10 
or so kW they see on cruising at convenient grid rpm's.  ;o)

..could be automated, and to reset that timer too.

..not yet.
