Assuming good maintenance a very long time.

Choose the right gas station to trial and stick with it for duration of the steps below. Not all diesel fuels are equal quality. Some are "dirtier" than others, and will negatively affect your mileage. Switching stations usually means switching the specific type of diesel fuel, so stay consistent. Find a gas station that offers a low price on diesel fuel, and also offers self service diesel pumps. Some stations offer further discounts if you pay with cash or debit. Your car dealership should be able to recommend a gas station that is best for your car.

A diesel ENGINE is typically built stronger than a conventional gasoline (petrol) engine, so it CAN last longer. The thing is that the rest of the car is NOT any different than your average, run-of-the-mill gasoline powered vehicle, and THAT is what will wear out first. Suspension, transmission, etc., will usually fail before the engine does.

It's a mechanical device. No one can predict that - it may die in a year, it may last decades.

Diesel engines do on average last a lot longer than petrol. However much depends on regular servicing. Not uncommon to see half a million miles or more on some engines.
though most diesel engines are more robust than petrol due to the higher compression pressures and vibrations factors that is not the only reason they can be expected to last many times longer than a petrol version. Nobody can give a definitive life expectancy due to so many variables. Loads. Speeds. Servicing. Terrain etc
if you do a bit of research I think you will find the more common expectancy given correct servicing is around 275.000 miles.

Ford Powerstroke diesels do not have a good reputation. The 6.0, for reasons unknown, have a cult following but horrible reliability. We got a crop of them at work around 2005 and none of them are still on the road. Injector problems were rife, with the maintenance schedule modified to require servicing of the injectors every 5000 miles to maintain the power train warranty. At least one of the trucks was literally in the shop for engine trouble more time than it was on the road for the two years we kept it. My own 2005 F350SD work truck was towed more than a dozen times in the last year. One of the times was when the EGR valve jammed open 12 miles from paved road and the engine would not let me touch the accelerator. I nursed it back to the highway, playing the gears in 4 lo, about the time the tow truck got there from town an hour and a half later. Another 6.0 sucked in the shredded remains of the turbo that came apart while climbing a steep hill, doing $10,000 damage. The Fortune 100 company I work for still buys Ford trucks, but I have one of the last diesel light trucks they have bought.
