With more than 2,200 service centers in North America, Jiffy Lube® is the largest system of franchised and company-operated service centers in the fast lube industry, servicing approximately 27.5 million customers each year. Headquartered in Houston, Jiffy Lube® International is a wholly owned, indirect subsidiary of Shell Oil Company. Jiffy Lube® pioneered the fast oil change industry in 1979 by establishing the first drive-through service bay, providing customers with fast and professional maintenance service for their vehicles. Jiffy Lube® was created to fill a gap left by the departure of full service gas stations and the emergence of the self-serve model. It also accommodated the shift from the do-it-yourself oil change market (DIY) to the installed motor oil market, or do-it-for-me (DIFM). Over the next two decades, more than half the growth in the installed market went to fast lubes.
