Diesels don't pink and have no ignition timing. I also have severe doubts that
premium diesel achieves anything whatsoever other than increasing the profits of
the oil companies.

They claim it has increased lubricity and doesn't wax up as easily in
very cold weather. No particular axe to grind, just saying that's how
they justify the higher price.

Side note: diesel prices are on a par with petrol in the local filling
stations, allegedly because of over-supply.

Given that cracking a gallon of petrol takes a pint of oil, one can see
why petrol should be more than diesel.

Shame the additional fuel usage for cracking isn't included on the CO2
per mile figures.
