  • Now how about the gas mileage?
  • Well, there are a number of aspects to look at.
  • So what are they?
  • One is Vapor Pressure. Have you ever noticed that gas is more expensive in the summer, but it also gets better mileage?
  • Hmm, I was curious why I tended to get better mileage in the warmer weather.
  • Yup! That's why. Another factor that contributes to your gas mileage is friction.
  • There are many different factors that play part in getting the best gas mileage: Vapor pressure, friction, drag coefficient, momentum and rolling resistance
  • WOW! This is pretty cool stuff! What else?
  • Do you know that the shape of your vehicle plays a substantial role in your car's gas mileage?
  • Vapor Pressure - - gas is made up of mixed long and short molecules - energy is created by splitting the molecules - the shorter molecules are cheaper, but also evaporate faster -the EPA requires a smaller amount in the summer to prevent larger amounts of pollutuion pollution
  • No, I didn't know it made that much of a difference.
  • Yup! Just like you can use the natural momentum your vehicle produces to further increase your gas mileage. Also, you can use the rolling resistance provided by your tires.
  • Friction - - Most vehicles lose up to 12% of their MPG (miles per gallon) for every 10 MPH you go over 50 MPH. For example: At 60 MPH you would be losing 12%, at 70 MPH you would lose approximately 24%. - the longer you continue to drive at a higher speed the more gas you will waste
  • Gee thanks, man! you have been extremely helpful!
  • No Problem, anytime, have a great day! Don't forget to check your tire pressure!
  • Drag Coefficient - - this is the measurement of how easily air moves around your vehicle - you want the least amount of frontal surface (within reason) - to obtain this, avoid vehicles with box fronts
  • Momentum- - is created with mass (x) velocity -most cars weigh 1800-5000 lbs, providing a lot of opportunity to take advantage of cruising on your vehicle's momentum, especially while driving in the city and taking off from a red light
  • Rolling Resistance - - always keep your tires at the recommended PSI (pounds per square inch), this will ensure you get the best advantage possible for your vehicle - owners have control over this by inflating and deflating the tires pressure - the harder the tire the better the mileage you will get
