Gas Saving Tips for Cambridge Drivers
- Park in shaded areas when possible — parking in the sun increases evaporative fuel loss from your tank and makes the engine work harder to cool the cabin when you start driving.
- Combine errands into single efficient trips rather than making multiple short trips. Cold engines use significantly more fuel — letting the engine warm up across one longer trip is far more efficient.
- Check tire pressure monthly, especially as seasons change — tire pressure drops about 1 PSI for every 10-degree Fahrenheit temperature decrease.
- Fill up on Monday or Tuesday mornings — gas prices typically rise Thursday through Sunday as weekend demand increases, then reset lower early in the week.
- Use the GasBuddy or Waze app to compare prices within 5 miles of your location before every fill-up. Even a 10-cent difference on 15 gallons saves $1.50 each fill-up.
