I learned that most diesel cars and trucks are still dependent on electronics for fuel injection and also have a higher minimum-quality of diesel.

The prepper nerds seem to advocate for Cummins 12-valve engines from the 1990s or the Toyota 1HZ.

There's a whole lot of old diesel LandCruisers out there. I'm guessing that's the sweet spot for it still being a normal car that mechanics can maintain while still being comfy and looking cool.
