I think this is off topic and I'm not the expert but it's a relatively reliable and established process that replaced lead in gasoline. I did some quick digging and didn't turn up any research of an alternative to ethanol for anti knock so perhaps this is why.
- MBCook 2y agoEthanol free lead free gasoline works just fine. Some stations sell it. It just costs more because the ethanol is subsidized. Cars don’t need ethanol. In fact they don’t like it. It causes problems for older cars, the auto industry had to adjust things to be able to survive a certain percent ethanol without damage.
- ahartmetz 2y agoEthanol breaks down or degrades certain polymers (formerly) used in fuel systems. But in the actual engine, it's fine: it has lower energy content but a very high octane rating compared to other constituents of gasoline.
