Number: RL34431 Title: The Disparity Between Retail Gasoline and Diesel Fuel Prices Authors: Robert L. Bamberger and Robert Pirog, Resources, Science, and Industry Division Abstract: This report provides background and identifies some of the likely factors and forces in world markets that may have contributed to the evolution of the relative prices of gasoline and diesel fuel over the past several years. Among these are strong international demand for diesel fuel; product mix decisions by refiners, and refinery investment to meet more stringent limits on the sulfur content of diesel fuel; the similarities between diesel fuel and home heating oil; and the effect on retail prices from local market conditions.
