Ok, ok, ok, other then water possibly scoring fuel injectors in four-stroke applications, what are the serious consequences of water in the fuel for your average, everyday automobile engine, hmmmm? Pray do tell... (We're not talking 'bout frozen fuel lines, plugged filters, rough running, poor idle, etc., etc., etc.; what serious problems?) And we're also not talking about gallons of water in the fuel system and intake left to rust-up everything solid! We're talking about the amount of water that can be held in suspension by the ethanol blended fuel and ingested by the four-stroke engine in question. (Now remember, us old-timers can remember the day when high-performance aircraft engines ran water injection in the intake, so choose your words carefully.) GO!!
