Poor MPG is from the misfires. Swap the spark plugs and clear the codes. If they come back, change out the coils. Could also be an fuel injector issue. Fix ASAP, misfire contribute to raw fuel migrating to the catalytic converters and clogging them up. Also an oil change never hurts and has nothing to do with the fuel mileage.

Why are you disregarding your mechanic and not replacing the coils?
