Abstract

API conducted a program to collect detailed chemical composition data from a broad range of commercial gasoline samples with objective of using this information as “prior arts” to maximize freedom of operations on a broad spectrum of fuel compositions. The data collection and fuel composition analysis was performed for API by Southwest Research Institute (SwRI). SwRI formed a consortium of petroleum companies in the early 1980s to conduct a monthly survey of fuel quality. SwRI collects fuel samples from service stations in 62 U.S. cities, analyzes them and distributes reports to consortium subscribers. About 350 samples are collected each month. For this study, the subscribers gave API permission to (a) select a stratified subset of 590 of the SwRI gasoline survey samples collected in January and July of 2008, (b) augment the dataset with measurements of the concentrations of up to 610 individual chemical compounds in each sample, and (c) publish the results.

Fuel Sample - MIAMI, FL - Petroleum Administration for Defense District (PADD) 1

The f ollowing pages contain inf ormation on the chemical composition and property characteristics of a commercial

gasoline f uel sample collected in a specif ied geographic area denoted by city , state and "PADD" number. PADD is

an acrony m meaning "Petroleum Administration f or Def ense Districts" and is commonly used by agencies such

as the US Energy Inf ormation Administration f or classif y ing petroleum product supply and consumption patterns.
