Practical tips to pay less
- Fill up before Thursday. Prices rise toward the weekend.
- Check stations near 01820 or Lowell. They beat highway exits.
- Use GasBuddy or rewards apps. Many cut 5 to 10 cents per gallon.
- Pay cash for posted discounts of 5 to 10 cents.
- Stop at the first pump click. Topping off harms the vapor system.
- Set tires to door-jamb pressure. This boosts efficiency 1 to 3%.
