I think I have that gas separation thing going on. My engine pings and looses power up hills. I bought gas last march and have added gas to it with higher octane since, plus stabil and seafoam. It's a 55 gallon cocktail now and still not potent. I found a station that still sells real gas without ethanol and I guess I'll sputter around until I get below half a tank and then fill up with unleaded 91 octane (no alcohol) and see what happens, any thoughts?
