    . Check for codes.

    . Use full synthetic engine oil and transmission fluid. Together, they should increase gas mileage 8 to 10%.

    . Clean MAF Sensor with MAF Sensor Cleaner.

    . Replace Oxygen Sensor, air filter, and Engine Coolant Temperature (ECT) Sensor, if you suspect they are part of the problem.
