Buy A Diesel Automatic Car For Fuel Efficiency
When it is time for you to buy a new car, it is a good idea to take a look at one that is powered by a diesel engine. At one time, these cars were marketed on the fact that diesel fuel was cheaper than unleaded gasoline. Once the oil companies sensed the increase in demand, the price for diesel fuel became more comparable and in some cases even a little higher. Even at the more expensive price, diesel automatics are still more efficient than their counterparts so they are cheaper to maintain in the long run.
In the 1970’s, the car companies reacted to the oil shortage by producing automatic vehicles powered by diesel. While companies like Mercedes had lots of experience manufacturing these types of engines, American car companies started with a standard engine and converted it. They quickly discovered that this was not the way to go. Higher pressures required with the use of diesel were causing head gaskets to blow and engine blocks to crack. Even though they are less expensive to run, people were turned off by the mechanical problems.
The gasoline engine works when the spark plug lights the fuel. Diesel engines run on pressure and heat. They are cooler than gas engines and the fuel converts to mechanical energy more efficiently so less is wasted. The energy that would be manifested as heat is instead transferred to the wheels. The net result is less fuel needed to travel the same distance.
Consider buying a car that runs on diesel the next time you are in the market for a new set of wheels. History has taught us that fuel prices are only getting more expensive as oil becomes harder to find and extract from the surface of the earth. You will do yourself a favor if you locate and buy an available car that gets the best gas mileage.
