Crude prices appear to be setting in place at the all time high levels. With this, gasoline has become a pretty premium commodity. The price of gasoline appears to be set for a long time at record high levels and many commuters are left trying to find the most efficient ways to increase mileage. To start saving money at the fuel pump, consider this cheap tip to change your spark plugs.

First, having basic knowledge of how your engine works will help understand what changes can be made. An automobile engine takes minute amounts of fuel and air into each piston chamber. This mixture is then pressurized by the piston moving upward. This pressurized mixture explodes through a spark transmitted by the spark plug.

After this spark is introduced, the mixture “explodes” and the resulting expanded gaseous state is the power used to operate your vehicle. During normal operation, an engine will repeat this process thousands of times every minute (thus – the term RPM’s , or Revolutions Per Minute). Each cylinder in your engine produces this exact same process over and over again – for example if your car has a V-6 engine, there are 6 chambers doing this at the same time.

Now, there are several ways to enhance this process, making it more efficient. A great place to start is with your spark plugs. The electricity emitted by spark plugs can be influenced by the quality of the plug itself. A more efficient, higher quality plug will increase the efficiency of this ignition. For example, the seals of the plug may leak additional air, causing some of the electricity power to be lost and as a result, a less efficient explosion occurs. This leads to needing more revolutions to achieve the same power output, and thus uses more gasoline.

Using a high performance spark plug will make your engine operate better. In general, you can expect a 3% increase in mileage by using a high quality spark plug. The rate of return is very quick, as spark plugs cost about the same as one gallon of fuel at today’s prices.
