Drive Efficiently
-Easy on the pedal (Jackrabbit starts from one set of lights to the next increases fuel consumption by 37%)
-Smooth sailing (Keeping a steady speed uses less fuel. Accellerate smoothly and avoid hard breaking.)
-Be idle free (10 seconds of idling uses more fuel than restarting your engine.)
-Combine trips (Combining several trips into 1 [like trips to the grocery store, etc.] can cut fuel use and emissions from 20-50%.)
-Travel light (Every additional 100 lbs. increases fuel consumption by 2%.)
-Use a fuel consumption display (You can keep track of instantaneously how many litres per hundred kilometres you are using. If you can adjust your habits, you could reduce consumption by 10%.)
Maintain and Save
-Tire pressure (one under-inflated tire can increase fuel consumption by 4% and reduce the life of the tire by 15 000 km.
-Motor oil (Using worn out oil can increase fuel consumption by 4%.)
-Air Filter (Fuel use can increase by 10% if air filter is clogged.)
-Tune ups (Keeping your car in tune can reduce consumption by up to 15%.)
Drive Less
-Carpool (It saves you money and reduces pollution.)
-Let someone else do the driving (Take transit, you can relax on the way to work and it's cheaper than taking a car.)
-Get active (Choose to bike or walk instead of drive!)
-Telecommute (Work from home - save the drive.)
