Gas Saving Tips for Tacoma Drivers
- Use regular unleaded unless your owner's manual specifically requires premium. For the majority of vehicles, there is zero performance benefit from a higher grade.
- 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.
