ways to reduce gasoline usage

  1. Avoid high speeds. Calculations demonstrate a decrease of 3 miles per gallon between 55-65 mph, which rises to 4.3 mpg between 55-70 because of wind resistance.
  2. Avoid jackrabbit starts. Gentle acceleration definitely cuts down on gas usage. The "Driving Change" pilot program in the Denver area harnesses an innovative accelerometer (made by Cartasite, Inc.) with the access of the Internet to help motorists track their driving techniques in an effort to help reduce air pollution and increase mpg.
  3. Avoid unnecessary sudden braking. Coast to a stop to save gas and lower the amount of asbestos fibers in the air.
  4. Only use "cruise control" on the open highway. In heavy traffic, it simply wastes gas.
  5. Practice optimized shifting techniques. Get into higher gears as quickly as possible.
  6. Switch off the air conditioner to save 5% to 15% of the energy your car uses.
  7. If idling is anticipated for over 60 seconds, shut the engine off.
  8. Lighten the load: 1% of fuel efficiency is lost for every 50 pounds of extra weight in your trunk.
  9. Remove bike, luggage, or ski racks from the top of your SUV or truck for less wind resistance.
  10. Keep tires fully inflated to manufacturer's specifications for a 3% gas savings.
  11. Use a multi-grade (versus "straight") motor oil to improve mileage by 1.5% to 2.7%.
  12. Keep your vehicle in good state of tune.
  13. Lastly, practice combining errands. This reduces "cold starts," which account for a disproportionate amount of air pollution.

Yes if the truth be known, in some moments I can bruit about that I approve of with you, but you may be making allowance for other options.
