Gas Saving Tips for Tempe Drivers
- Pay cash at stations offering a cash vs. credit discount — typically 5-10 cents per gallon savings that adds up significantly over time.
- Do not let your tank run below a quarter — low fuel levels increase wear on electric fuel pumps and can lead to emergency fill-ups at inconvenient and expensive stations.
- 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.
