Gas Saving Tips for Dover Drivers
- 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.
- Avoid idling for more than 60 seconds. Modern engines warm up faster while driving than idling, and idling gets literally zero miles per gallon.
- 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.
