our refining and wholesale marketing gross margin is the difference between the prices of refined products sold and the costs of crude oil and other charge and blendstocks refined , including the costs to transport these inputs to our refineries , the costs of purchased products and manufacturing expenses , including depreciation . the crack spread is a measure of the difference between market prices for refined products and crude oil , commonly used by the industry as an indicator of the impact of price on the refining margin . crack spreads can fluctuate significantly , particularly when prices of refined products do not move in the same relationship as the cost of crude oil . as a performance benchmark and a comparison with other industry participants , we calculate midwest ( chicago ) and u.s . gulf coast crack spreads that we feel most closely track our operations and slate of products . posted light louisiana sweet ( 201clls 201d ) prices and a 6-3-2-1 ratio of products ( 6 barrels of crude oil producing 3 barrels of gasoline , 2 barrels of distillate and 1 barrel of residual fuel ) are used for the crack spread calculation . the following table lists calculated average crack spreads by quarter for the midwest ( chicago ) and gulf coast markets in 2008 . crack spreads ( dollars per barrel ) 1st qtr 2nd qtr 3rd qtr 4th qtr 2008 .

Table:
crack spreads ( dollars per barrel ) | 1st qtr | 2nd qtr | 3rd qtr | 4th qtr | 2008
chicago lls 6-3-2-1 | $ 0.07 | $ 2.71 | $ 7.81 | $ 2.31 | $ 3.27
us gulf coast lls 6-3-2-1 | $ 1.39 | $ 1.99 | $ 6.32 | ( $ 0.01 ) | $ 2.45
in addition to the market changes indicated by the crack spreads , our refining and wholesale marketing gross margin is impacted by factors such as the types of crude oil and other charge and blendstocks processed , the selling prices realized for refined products , the impact of commodity derivative instruments used to mitigate price risk and the cost of purchased products for resale .
we process significant amounts of sour crude oil which can enhance our profitability compared to certain of our competitors , as sour crude oil typically can be purchased at a discount to sweet crude oil .
finally , our refining and wholesale marketing gross margin is impacted by changes in manufacturing costs , which are primarily driven by the level of maintenance activities at the refineries and the price of purchased natural gas used for plant fuel .
our 2008 refining and wholesale marketing gross margin was the key driver of the 43 percent decrease in rm&t segment income when compared to 2007 .
our average refining and wholesale marketing gross margin per gallon decreased 37 percent , to 11.66 cents in 2008 from 18.48 cents in 2007 , primarily due to the significant and rapid increases in crude oil prices early in 2008 and lagging wholesale price realizations .
our retail marketing gross margin for gasoline and distillates , which is the difference between the ultimate price paid by consumers and the cost of refined products , including secondary transportation and consumer excise taxes , also impacts rm&t segment profitability .
while on average demand has been increasing for several years , there are numerous factors including local competition , seasonal demand fluctuations , the available wholesale supply , the level of economic activity in our marketing areas and weather conditions that impact gasoline and distillate demand throughout the year .
in 2008 , demand began to drop due to the combination of significant increases in retail petroleum prices and a broad slowdown in general activity .
the gross margin on merchandise sold at retail outlets has historically been more constant .
the profitability of our pipeline transportation operations is primarily dependent on the volumes shipped through our crude oil and refined products pipelines .
the volume of crude oil that we transport is directly affected by the supply of , and refiner demand for , crude oil in the markets served directly by our crude oil pipelines .
key factors in this supply and demand balance are the production levels of crude oil by producers , the availability and cost of alternative modes of transportation , and refinery and transportation system maintenance levels .
the volume of refined products that we transport is directly affected by the production levels of , and user demand for , refined products in the markets served by our refined product pipelines .
in most of our markets , demand for gasoline peaks during the summer and declines during the fall and winter months , whereas distillate demand is more ratable throughout the year .
as with crude oil , other transportation alternatives and system maintenance levels influence refined product movements .
integrated gas our integrated gas strategy is to link stranded natural gas resources with areas where a supply gap is emerging due to declining production and growing demand .
our integrated gas operations include marketing and transportation of products manufactured from natural gas , such as lng and methanol , primarily in the u.s. , europe and west africa .
our most significant lng investment is our 60 percent ownership in a production facility in equatorial guinea , which sells lng under a long-term contract at prices tied to henry hub natural gas prices .
in 2008 , its .
