Will ethanol work in fuel-injected engines?

Yes. Other components of gasoline, such as olefins, can cause deposits that result in fouled fuel injectors. However, since 1985, all ethanol blends and nearly all non-ethanol gasolines contain corrosion inhibitors and detergent additives designed to prevent injector deposits. These detergents have been very effective in alleviating the problem of fouled fuel injectors. Won't ethanol burn valves?

No, because ethanol burns cooler than gasoline. This is the reason that many high-powered racing engines use pure alcohol for fuel.
