The crude oil based fuel price is constantly increasing in India, So it is compulsory to utilize the fuel properly by the user. As most of the driver tends to press the gas pedal unnecessarily, the fuel used at that particular condition is excess than the requirement. This experiment focuses on improving the fuel economy by warning the driver to drive their vehicles in optimum Specific Fuel Consumption (SFC) range using electronic SFC Speed Range Indicator. In variable speed Internal Combustion Engines there will be an optimum SFC range for a particular load and Engine Speed. Our system will monitor the Engine speed and load continuously and also compare the values with best SFC speed range graph and depends on these values the three Light Emitting Diode (LED) on Specific Fuel Consumption Speed Range Indicator(SFCSRI) will glow accordingly to mention the driver about the optimum, low or high speed. This helps the driver to drive their vehicles on optimum SFC range
