I would definatly replace the fuel filter like said above. and also winter gas is known to cause bad mpg.
Sea foam will work wonders to fix everything that is gummed up.
next time you go away for a long time, mix a half can of seafoam or startron into the tank and cruise around a bit. Startron works better with ethanol fuels than sea foam but both are a good cleaner/fuel stabilizer
No, ethanol has a higher octane rating than normal gasoline. Ethanol is however much more susceptible to water.
OP: You likely need to put some dry gas
and/or a fuel stabilizer
in the tank if you haven't run that tank out yet. A bottle of fuel injector cleaner
would probably not hurt, but don't expect miricles.
What kind of MPG are you getting? How many miles? How long did it sit?
