When water comes in contact with alcohol, they attract but still the mixture still sinks to the bottom just like water does in pure gasoline. That was my understanding. That's what Sta-bil ethanol treatment is supposed to do. It's supposed to keep the water/alcohol suspended in the gasoline. Or so they say. I've wondered if regular Sta-bil even works. I just got through running out the gas in my spare lawnmower (a Troy Bilt) Saturday and it's been in there for 2 years and never been treated with anything!

Could the higher octane fuel cause the engine to run in a "happier place", you ask? Sounds like it could to me. I always thought the 2.2l in my '95 Subaru was always straining. That engine had NO GUTS at all. No problem with that except that if it had no guts then why didn't it get higher mileage? It ran like a watch. After 138,000 miles (easily 3/4 open highway driving) it averaged 24.24mpg. Fairly low in my opinion.
