I have a "1999" Chevy Blazer that went from 280-320 to a full tank of gas to around 180-200 to a full tank. I've replaced everything since 2007 and the only thing I can find is the change in gas. %10 percent "Ethanol" is killing my Blazer. The only other thing it might be is the "Torque Converter Solenoid" which I haven't replaced yet. I bought a "CarMD", and it showed no problems.
Of course using 10% ethanol will effect mileage but not by that much. A defective torque converter solenoid will defiantly cause excess fuel usage as the converter is not locking up and your engine is turning far more RPMs than it would if all was working as it should. Replace the solenoid.
