Diesel in a homebuilt?

One thing that everyone should keep in mind, is that automotive diesels run
on diesel fuel, and everyone wanting diesel engines for their airplanes is
going to want to use jet fuel.

Jet fuel does not have the good lubricating properties that diesel fuel has,
and may tend to wear out the automotive fuel pumps in short order.

The lubricity aspect is certainly important. But I'm not so sure
everybody will be wanting to use Jet A1. Just like many recreational
fliers bring their own mogas to the field, I can imagine pilots
bringing jerrycans of off-road diesel (coloured red in my country,
and in many other European countries I believe).
Those with a trailered plane can just stop at a petrol station, of course.

Ideally, both diesel and Jet-A1 could be used.
But with today's fuel prices, everyone makes his own compromise.

I'm going to show my ignorance again but Diesel and
Jet a1 can be used in a diesel engine?

i would refer to the engine's manual to be safe; this can differ from engine
to engine. thielert's centurion 2.0 is certified for both, jet-a1 and
diesel. however, airplane manufacturers may restrict that; diamond's da-40
tdi is certified for jet-a1 only (according to the manual of an aircraft
equipped with the centurion 1.7).
the centurion 4.0 engine is designed for jet fuel only.

another aspect i'm not familiar with is if fuels sold as "diesel" are the
same in europe and the usa. thielert's internet site mentiones diesel fuel
according to european standard EN 590.
