Did anyone else see the expose they did on Jiffy Lube on the local California news channel? Someone sent me the vid on YouTube, I think, so if you want to hear about why never to go here, check it out.
The crux of it is they scam a large percentage of their customers. Now I'm sure that there was a big crackdown after the viral effect of that news story, but I am hard pressed to believe that it doesn't happen at all anymore. Changing filters, running specialized machines, etc. are hard to track the concrete effects of and whether they actually did or not.
Seriously, I would only go here and purchase something beyond a simple oil change if I personally knew the employee. Otherwise, prepare to get way overcharged for work that they said they did but probably didn't.
It's a crazy mixed up world out there, kids.
