A Method of Distributing Unleaded Gasoline

Faced with a Federal Regulation stating that all unleaded gasoline sold after July 1, 1974 must contain no more than 0.05 grams of lead and 0.005 grams of phosphorus per gallon, a study was made to determine how to distribute unleaded gasoline from the refinery to the customer without exceeding these contamination limits. This study showed that the handling procedures normally used for unleaded gasoline were inadequate.

New handling procedures were developed and field tested. These field tests confirmed the validity of the new handling procedures which were then adopted on a company wide basis.

Analysis of an extensive number of service station samples taken each month since imposition of the regulation on July 1, 1974 have confirmed that the new method of handling unleaded gasoline has enabled this Midwest refiner to meet the prescribed contamination limits on lead and phosphorus.
