Save on Gas? Tailgate

I recently read that the optimal gas efficiency speed on the highway is about 60mph, in general. For every 5mpg over 60, the increased air resistance causes a drop of about 10% in fuel efficiency. So if you were driving 75mph, you would be spending about 30% more gas then if you were going 60.

I found this graph from a government website (click the graph to visit the site).

In some states (like Michigan), the speed limit is 70mph, but lets face it, when was the last time you drove “speed limit” on an uncongested highway?

The reason why your efficiency drops so rapidly after 60mph is due to air resistance. Logic would dictate that if you decrease your air resistance, you increase your gas efficiency. Auto makers have been making their cars more and more aerodynamic – able to cut through the air with less resistance.

Another solution – tailgate.

In racing, they call it “drafting”. NASCAR drivers use it, and so do bike racers like Lance Armstrong.

Okay, tailgating is stupid - It causes many accidents, some fatal.

If you know how to follow a car and which kind of car to follow, however, you will notice a decrease on the amount of gas you use.

The science is simple – the car or truck in front of you “breaks the wind” for you, hence reducing air resistance. The bigger the vehicle in front of you, the farther away you can be in order to reap the benefits.

With my sedan, I often follow (not tailgate, though – too dangerous) SUVs or semi-trucks – prefer SUVs, though.

Where is my proof? Well, I don’t really have any solid proof. However, on a recent trip, I rented a 2006 Ford Taurus and drove it about 300 miles. On the way there, it was sunny and dry so I followed an SUV down I-75 going at about 75mpg. I got there in about 4 hours and used less ¾ tank of gas.

On my way back, it was night so I did not follow behind any cars. I went about 65 or 70 (speed limit). It took me a longer to get home and I used an entire tank of gas!

Following behind another car is also a good idea when the wind is blowing hard. On my way back from school, going down a highway I notice a big difference, especially on a windy day, between taking the lead and following. I could feel the car get heavier and the need to press the gas peddle harder.

Do NOT tailgate
(its illegal). A skilled driver can save on gas, however, by leaving a safe, but close, distance between you and a driver in front of you. Of course, you could always get yourself one of these bumper-stickers:

If you are as tired of high gas prices as I am you will be very interested in these News reports from NBC and FOX news. They reveal how you can start saving 7%-19%. They also reveal how you can turn this into a very profitable venture. I have personally used the product with very good results..19.5% savings. To test the product I put it in my wife's car an '05 Cadillac SRX. She was not aware I put it in the car. I did it this way so that she would not subconsciously drive any differently and the final result 19.5% increase in milage. Quite astounding. I did the same with my Dad's '06 Ford F-150 and he got 15.3% increase. You really should check this out. fuel prices prices
This is truly a winner.

But hybrid technology paves the way for plug-in hybrid technology which paves the way for all-electric vehicles.increase miles per gallon, fuel saver, increase gas

mileageStill, hybrids run on gasoline, increase miles per gallon, fuel saver, increase gas mileage which is not an alternative to gasoline no matter

Fuel is the adrenaline of any car, truck or engine. Thus, it is every vehicle owner's wish to enhance the fuel of their car and save more of it as well. With this in mind, the most innovative fuel-saving tool in the automotive industry was conceptualized and created: the Tornado Fuel Saver. An automotive air channeling tool that creates a swirling air motion, the Tornado Fuel Saver allows the air to move in a faster and more efficient way by whirling air around corners and bends. Hence, more fuel is saved. Search engine optimization, Try to Be happy
