Gas Saving Tips for Cary Drivers

Check fuel prices across state lines if you regularly travel near a border. State fuel taxes vary by up to 50 cents per gallon — the savings from crossing into a lower-tax state can be dramatic.
Use cruise control on highways to maintain steady speed. Speed variability increases fuel consumption; steady-state driving at 65 MPH uses significantly less fuel than oscillating between 55 and 75.
Avoid idling for more than 60 seconds. Modern engines warm up faster while driving than idling, and idling gets literally zero miles per gallon.
Park in shaded areas when possible — parking in the sun increases evaporative fuel loss from your tank and makes the engine work harder to cool the cabin when you start driving.
Combine errands into single efficient trips rather than making multiple short trips. Cold engines use significantly more fuel — letting the engine warm up across one longer trip is far more efficient.
