All Jiffy Lubes are not equal. Now some are even franchises. You need to make a note of which Jiffy Lube shops are competent and which locations are trustworthy. Just because I get paid to shop them and get reimbursed does not mean that I will return. There are some I will not take my car to again, and there are some that I return to again and again. Some issues I can recall off top of my head are, not tightening the oil filter, stripping the drain plug, not tightening the drain plug, telling me that I needed a new belt when the one on my car was only 3 days old, telling me my fluid was too dirty. On the other hand, some of the locations do a good job, give an honest service check, and only try to sell you things your car needs or will need soon.
