Minimum km running required for diesel cars

[Optimus7]

I own a Fiesta diesel, I take it out 2 to 3 times a week. The engine starts in the first crank itself. If I take my car out, my minimum driving will be about 40 kms. I avoid short runs as much as possible. I think its better to take the diesel vehicle out more, purely from a maintenance point of view, as sgiikt rightly pointed out.

Its a misconception. Its just that every morning have a habit, of putting it in idle for about 5 minutes in normal and 10 minutes in winter. No acceleration whatsoever. Just idle.

While shutting it down wait for at least 1 minute before shutting it down.

Modern Diesel are low on maintenance just like petrol now. They are great during rainy season. chances of messing them up is way lower than petrol.
