Well I can tell you that (though I hate to support a company that treats their employees as shitty as they do....) Jiffy Lube DOES NOT ever use old, recycled, re-used, etc. oils. All oils used are new and the same as if you were to buy them in an AutoZone.
We did use what we called 'bulk oil' which is the exact same thing as whats in the bottles. It is technically cheaper, but thats just the cost to the owners because it is bought in bulk, not cheaper quality.
I will tell you that I have heard horror stories about Econo-Lube using recycled oil and only changing oil filters once a year or something. No thank you.
LOL if anyone else wants to know anything about their favorite national fast-lube, let me know...I dont work there anymore so I guess I have no reason to lie
good luck
