Speed is the biggest factor on fuel economy. Driving at 55 mph instead of 65 or 75 will save on gas. Tests have shown increasing speed from 55 mph to just 65 mph dropped fuel economy from 40 mpg to 35. While driving at 75 mph can cost the car another 5 mpg.
Keep a steady pace; avoid hard acceleration and braking if possible. Frequent acceleration and braking can reduce mileage by 2 to 3 mpg. Driving with smooth acceleration, cornering, and braking will also extend the life of the automobile.
Don’t be a drag
When driving on the highway, more than 50 percent of engine power goes to overcoming aerodynamic drag. Carrying large items such as luggage racks and top-carriers reduce fuel economy.
Take the time to warm up the engine before taking off. Cars run most efficiently when they’re warm. Stopping and starting the car several times is a big factor, try to combine several short trips into one so that the engine stays warm.
Check your tires. Underinflated tires compromise handling and braking which in turn can reduce fuel economy. Check the pressure of your vehicle’s tires to make sure they are correct.
Idling is one of the worst things your car can do, when idling your car is getting zero miles per gallon. Turn off your engine if you expect to sit for more than about 30 seconds.
Practicing these simple tips should have you putting less money in your gas tank in more in your wallet in no time.
