What are the Fuel Economy Factors?

Their are many Fuel Economy Factors that change the value of your car’s gas efficiency. For example you must take good care of your engine so that it is a “finely oiled machine”. If your not using good spark plugs, or bought the cheapest ones you could find you may be cheating yourself out of mileage. For example their are spark plugs that burn with 4 leads instead of just one causing a hotter burn of the fuel and thus more power with less fuel. Simple things like the type of oil you use in your car help the engine stay clean and thus more efficient.
