You literally are only making yourself sound more like a fool. There is no corporate mandate to sell unneeded services or parts. At all. You are a liar who makes things up if you think "corporate" said that.

They don't charge labor on air filters, there is a markup, but it's often the same price as Autozone...you know why? Because Autozone buys them for $5 and marks them up to $12.99 and so does Jiffy Lube, except at Jiffy Lube you don't have to stick it in there yourself. There might be $1-2 difference tops. You can beat both of those places online obviously, but if you don't understand why that is, then I might have to explain how businesses work to you.

I'm a college educated, former Jiffy Lube employee (7 years), where my parents own 15 of them...so I'm most likely more educated than you on their practices.

I've worked at 5 different stores under 2 different owners (my parents and their JLube competitor) and there are DEFINITELY some idiots there and definitely some mistakes are made...but you are completely ignoring the volume they do compared to a mechanic-shop and how the % of issues is probably on-par or better than those shops.

And ownership makes a huge difference. My parents pay high wages, so there is very little employee turnover, while the other guy paid closer to minimum wage and people were in/out of there. I only worked at his stores because they were the ones close to my college.

I never tried to sell anyone anything they didn't need, nor did anyone at my parents stores.

At the other guy's stores, the workers definitely did not care about their job, have pride in their work, etc. They would also try and push things more to get the average ticket price up. They didn't directly try and screw anyone, but if some part/fluid had some wear on it they'd push it, even if it wasn't needed until the next service.

This brings me back to my point, that not every one is total shit, and they definitely don't have predatory practices. The worst you may get, even from a bad one, is them trying to sell an air filter or if a fluid isn't new'ish they'll try and sell a flush.
