I worked at jiffy lube..it sucks- i don't know about where you live, but i can pretty much promise you beyond a doubt- 99 percent of jiffy lube are scammers.
If you don't want to get scammed there, heres what you do. You order the cheapest oil change, and WATCH when they work on your car my friends. We had (and i have friends who work at 4 jiffy lubes around me) so much business, that we ran out of filters, so we reach in the trash can, and install filters from there. They don't leave the filters on there because it may be marked, so they slap used ones on there and clean it up. On more than one occasion, if a customer pissed the boss off, or they argued over the price, they'd go to the bay, and drain the used oil from the containers, and pour it into the crank case.
If you order synthetic, i'd like to say about 20 percent of the time- your not getting it. Atleast once every 2 weeks we ran out of synthetic, and they go out back and use bottled regular so it looks special.
really- i dont wanna type it all, the list goes on and on. I dont know how it is where you live, but in metro Atlanta- i know myself of 4 Jiffy lubes (thats ALL the jiffy lubes i know) are scam artists
Jiffy lube hires idiots. I was 16 or 17 in my senior year of highschool when i worked there. No drug tests or anything. half the time- the employees are doing pot or even cocaine in the pits when business dies down.
