When you take a look at car manufacturer information about the fuel consumption (or economy) they claim, you’ll see that you live in an era of extremely efficient cars. If you make the calculations for yourself, you’ll see that is not so.
The internal combustion engine (gas and diesel engines) have a design that is more that one hundred years old, and what is being improved throughout the time is the efficiency of operation, but the concept is still outdated. A gas or diesel engine uses about 30 percent of the fuel it consumes…the rest is lost mostly in heat.
Looking at the information sheets in windows of new cars you’ll see mileages of 18 to 25; 25 to 31, etc. But a simple procedure will tell you how much fuel you are really burning in your daily errands.
Next time you fill up the tank, do it until the nozzle jump off by itself, then set the partial odometer to zero and drive as you usually do. When the time comes to fill up the tank again, do it also until the nozzle jump off by itself, write down the mileage in the partial odometer and divide that number by the amount of gallons shown in the receipt. You’ll be surprised by the numbers.
With this little test you’ll be able to discover several things:
-The real mileage your vehicle is giving you
-Which brands of fuel gives you the best mileage (there is difference!)
-Which driving habits give you better mileage
-Early detection of mechanical and electrical problems in your engine by the drop in mileage (if you keep doing this every time you fill up the tank)
From what I’ve seen, sport utilities and pick up trucks usually give around 14-18 MPG, while a four cylinder car will be in the 20-27 MPG margin, which is a 50% more miles per gallon.
If you drive an average of 1000 miles a month (which is normal for most people), and switch from a sport utility vehicle to a four cylinder car, you will save around 20 gallons of fuel a month, which in turns, could be a saving of 50 dollars a month, or 600 dollars a year!
If we multiply this savings in gallons of fuel by the number of cars in the US, we could see that several tankers can get lost in their way here. The amount of pollution can be greatly reduced, and even the streets will become instantly “wider” by the use of smaller cars. All on top of personal savings for everyone driving a car
