Gas Saving Tips for Las Cruces Drivers

Plan fill-ups along your existing commute route rather than making special trips. A station you pass daily that is 10 cents cheaper beats a special detour to a slightly better price.
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.
