There's no question that it works.Uncle Sam used to pay me to mix up a cauldrons brew of demineralized H2O and methanol alcohol for injection into Douglas A-1 E Skyraiders,so the engines wouldn't meltdown on takeoff.------------------ I do believe there are other issues with regards to higher compression-ratios,and trade-offs with emissions.That's kinda a can o' worms.------------- With modern knock-sensor technology I believe automakers are able to achieve fairly high ratios with the electronics protecting the guts of the engine by limiting spark advance to head off detonation.So maybe the alcohol injection isn't as important an issue today as in past times.Since engine-makers are working on variable-compression-ratio technology,that may remain a big issue.
