2009 levels , we returned a portion of these assets to active service . at the end of 2010 , we continued to maintain in storage approximately 17% ( 17 % ) of our multiple purpose locomotives and 14% ( 14 % ) of our freight car inventory , reflecting our ability to effectively leverage our assets as volumes return to our network . 2022 fuel prices 2013 fuel prices generally increased throughout 2010 as the economy improved . our average diesel fuel price per gallon increased nearly 20% ( 20 % ) from january to december of 2010 , driven by higher crude oil barrel prices and conversion spreads . compared to 2009 , our diesel fuel price per gallon consumed increased 31% ( 31 % ) , driving operating expenses up by $ 566 million ( excluding any impact from year-over-year volume increases ) . to partially offset the effect of higher fuel prices , we reduced our consumption rate by 3% ( 3 % ) during the year , saving approximately 27 million gallons of fuel . the use of newer , more fuel efficient locomotives ; increased use of distributed locomotive power ( the practice of distributing locomotives throughout a train rather than positioning them all in the lead resulting in safer and more efficient train operations ) ; fuel conservation programs ; and efficient network operations and asset utilization all contributed to this improvement . 2022 free cash flow 2013 cash generated by operating activities ( adjusted for the reclassification of our receivables securitization facility ) totaled $ 4.5 billion , yielding record free cash flow of $ 1.4 billion in 2010 . free cash flow is defined as cash provided by operating activities ( adjusted for the reclassification of our receivables securitization facility ) , less cash used in investing activities and dividends paid . free cash flow is not considered a financial measure under accounting principles generally accepted in the u.s . ( gaap ) by sec regulation g and item 10 of sec regulation s-k . we believe free cash flow is important in evaluating our financial performance and measures our ability to generate cash without additional external financings . free cash flow should be considered in addition to , rather than as a substitute for , cash provided by operating activities . the following table reconciles cash provided by operating activities ( gaap measure ) to free cash flow ( non-gaap measure ) : millions 2010 2009 2008 .
