cars.com— According to cars.com the two most effective ways of limiting fuel consumption and reducing carbon output are car pooling and public transportation. Car pooling with family, friends or neighbors can reduce daily fuel consumption by 50%. Using fewer vehicles to transport more people not only reduces carbon output but also decreases traffic congestion.

Reducing a vehicles weight by removing extra objects or passengers improves fuel economy.

Accelerating slowly will consume less fuel then “Jack rabbit starts and full-throttle acceleration.” “Most vehicles are most efficient when cruising in their top gear at a relatively low speed.” When cruising in its top gear, a car’s fuel economy is directly proportional to its wind resistance. The more aerodynamic a car is, the less drag it has. An increase in drag causes a decrease in fuel efficiency. Removing luggage/ski racks and after market add-ons such as bug deflectors, window wind deflectors and sunroof wind deflectors increases aerodynamics and fuel efficiency. Because higher speeds cause the effects of wind resistance on fuel economy to be greater, it is more efficient to drive with the windows up and the AC on at higher speeds. At speeds below 35-40 mph there is little difference in the amount of fuel consumed by using AC or driving with the windows down.

Maintaining proper tire pressure as defined by a car’s manual (not the tire wall) improves fuel efficiency. Regular engine tuning (checking oxygen sensors and air filters etc…) also increases fuel efficiency.

Lower octane fuel is more economical than higher octane fuel. Even if a car’s manual ‘recommends’ higher octane fuel there aren’t “any long-term [penalties]” for using cheaper/lower octane fuel. “Technically, this makes the car less efficient, but not to a degree that negates the cost savings from the cheaper fuel grade.”
