I don't know about all jiffy lubes, but I have lived in L.A. and In Sacramento and have changed my oil at jiffy lube forever. Night and day from L.A. to Sacramento. I have never had any problems since I moved up North.
WOW! They sent a technician out there to help you and gave you another oil change for free, for possibly making a mistake, anyway doesn't Jiffy Lube have insurance for that kind of thing? Who is to say that you didn't drain the oil after they did your oil change to get a free engine? HMMMM?
