        Recent surveys indicate approximately
  14% of the driving public use leaded gasoline
  in vehicles that require unleaded gasoline. This
  fuel switching significantly increases automotive
  emisssions through the deactivation of
  emission control systems. This pamphlet
  answers the most commonly asked questions
  about fuel switching and addresses some
  current misconceptions concerning the
  "benefits" of switching.
 What Is Fuel  Switching?
        Fuel switching is the use of leaded
 gasoline in any vehicle designed to use
 unleaded gasoline. Cars which require
 unleaded fuel  have catalytic convertere^to
 control emissions.

                                                        shortens the life of spark plugs, exhaust
