Two Helpful Tips from the Maryland Department of Transportation to save Gasoline and reduce your Fuel Bill:

1. Maintain your Car

  • Get regular tune ups
  • Replace dirty air and fuel filters
  • Use proper grade of oil
  • Do not overfill your gas tank
  • Properly inflate your tires
  • Do not buy "aggressive" tread tires if your car does not require them

2. Use your car's engine wisely

  • Avoid excessive idling
  • Use cruise control on the highway
  • Shift up as quickly as possible when using a manual transmission
  • Run air conditioner when traveling over 40 mph (It is more efficient than with windows down)
