I imagine the engine is optimized to run on "average" gasoline for a given octane level, tuning compression ratio, spark timing, air mixture, etc. I'm not an I

  I believe the tuning is controlled electronically through software (this is what enabled VW Dieselgate). So a software update could enable the vast majority of cars to be able to use this fuel.

  You might find this youtube channel interesting: https://www.youtube.com/channel/UC2rzsm1Qi6N1X-wuOg_p0Ng/videos https://www.youtube.com/channel/UC2rzsm1Qi6N1X-wuOg_p0Ng/vid... He has run a gasoline engine on a whole slew of fuels, including some that may be surprising, such as isopropyl alcohol, various solvents, crude oil, and a 50% diesel gas mix. Gasoline engines can also run on pure propane, but the fuel pump, tank, and some other parts do need to be replaced. I guess the point is that gasoline engines are not in general super sensitive, while they still could be more optimized for certain fuels.

    Thats a low compression mower engine. Modern automobile engines are indeed quite sensitive to predetonation from slower ignition times offered by most alternatives without being designed for them.

      Maybe this can be handled by adjusting valve timing in software.
