It seems one of my favourite energy analysts, SRSRocco, has picked up the story:

He's a bit more succinct than I was explaining the original article:
"The article provides some sobering data suggesting that the global production of diesel fuel may have peaked.
Furthermore, due to the peak of conventional oil in 2005 and the considerable increase of U.S. shale light tight oil, the production of heavy fuel oil (not diesel, rather bunker fuel for ships, etc.) has also declined. Turiel explains in the article The Peak of the Diesel: 2018 Edition, that the refineries cannot make as much diesel from the U.S. light tight shale oil, so they are forced to crack the heavier fuel oil to make diesel. If true, what we have here is the cannibalization of the refinery system to continue to produce diesel at the expense of the heavier fuel oils.
If Peak Diesel has arrived, Peak Gasoline isn’t too far behind."
