Not surprising; this kind of thing happens throughout the automotive repair business, not just at Jiffy Lube; although they might be worse than other places. Around the Wichita Kansas area where I live, when the mechanics at Jiffy Lube aren't working on a car, they're standing in front of the business along the street holding a sign advertising their services, which tells me that Jiffy Lube has to be the bottom of the barrel for a mechanic!

Face it, most of us don't know much about our cars, especially if it is a newer vehicle. If Joe Blow mechanic tells me my thingamajig under the hood has gone bad and needs replaced, I am basically at his mercy. A big part of the problem IMHO, is the way mechanics are paid. They typically do not get paid by the hours they work in a day but they are paid according to the number of hours that get billed to a customer according to "the book." And if they are paid by the our then they can earn a bonus according to billed hours. So the important thing is to find someone you can trust and know won't screw you over.

BTW, there is a article in snopes.com at the link below about Jiffy Lube.
