Even a 400 HP Yak-52 will run just fine on MOGAS.

@LeSving, keeping in mind what it was ran on during the Soviet times, I think anything would an improvement! :)
What about TC/TN engine on the likes of Mooney, Malibu, SR-22T?

Yes you can run Yak52 on 78 octan Avgas or Mogas but you still need to add lot of lead add to them? can you throw UL91 in Yak52 and go for full power aerobatics ?!
Likely CS-STAN CS-SC202b allows it but maybe it flows better with some Smirnov Vodka 
UL91 is not Mogas…

UL91 is terrible stuff compared with Mogas, and oddly so (Smirnov is good stuff for engines ) Even standard off the shelves “environmental friendly” gasoline for lawn mowers and such (alkylate fuel, from for instance Aspen) has higher octane than UL91. Alkylate fuel is 100% pure alkylate, no ethanol, no lead, no nasty aromats. Storage life of several years. Add a dash of Smirnov (storage life of decades), and it’s a 100LL replacement right there.
Real aeroengines (2000+ hp) used water/(m)ethanol injection. Modern car engines do essentially the same.
