> Why would I change the oil in my car when it's $40 to get it changed at the shop?

Because you like your car...

Every decade or so, I try a fast oil change place, usually when I'm in a hurry, and it sells me on changing my own oil for the next decade, because it's either obscenely overpriced, they screw up my car somehow, or both.

Last time I took vehicles in for oil changes, it cost nearly $200 for my truck (I know it takes a lot of oil, but ffs...), and for the car, they didn't get the airbox back together properly, so I had a nice post-air-filter leak. They even left the bolt they couldn't get lined up sitting in the windshield air inlet tray - because they'd not lined the filter box up right. And, they forgot a crush washer on the drain plug, so I had a dinner plate sized oil puddle under the car in the morning. Sorry, I see no point in paying someone to screw my vehicles up like that.

DW took our car to Costco for a free scheduled tire rotation (mandatory to maintain the tire warranty) about a month ago.

She called saying "they're saying 'the lug nut broke'"; I was thinking (and asking) "how is that possible (it can't possibly be a defective lug nut)?" 10 minutes later "the stud is broken"; 5 minutes later "they [Costco] admitted to breaking it".

The resolution was to have a local shop replace the lug stud and get reimbursed for the repair cost: $125 (the part might have cost $2)!

I chalk this episode up to them hiring warm bodies lacking any mechanical experience or aptitude (to the extent of not being aware of "righty tighty, lefty-loosey") and handing them an impact wrench.

Huh. A couple months back, I helped someone replace a broken stud in their garage with some C-clamps and hammers. On a lot of vehicles, it's just "press the old one out, pull the new one in."

But there's a reason that r/justrolledintotheshop talks about "uggaduggas" as a torque spec - to make fun of the people who just let an impact driver pound away at things like lug nuts. Cross threaded? Screw it, more uggaduggas! It'll snap when someone takes it off? Not My Problem!

Oddly enough, it's not always righty tighty. I rode motorcycles that had axles that were the opposite (so normal rotation would tighten them), and it was well known on the forums that if you let a shop just go at it, they'd try to loosen it, tighten it, smash the spacer, and your wheel bearings would then fail in short order. I always either watched the shop take my wheels off, or just took the wheels off myself and took them in to get the rubber replaced (alarmingly frequently - I was riding a lot).

To be fair, it might not have been Costco's fault, it could have been the last guys to put the wheel on who impact gunned the fuck out of it, or shitty studs or lugs, or a combination of all three. That said, Costco should have had zero problems replacing a broken stud on the spot, any business who regularly removes wheel from cars should be prepared to replace a few studs here and there. It would be like hiring a guy to change your light fixtures but he can't finish because he didn't bring any spare wire nuts because he assumes their are already good wirenuts on the old light fixtures.

Well, the tires were purchased (and mounted) at Costco, and rotated at least once previously by Costco (since the path of least resistance for warranty maintenance is for them to have the records of doing the (free rotations) themselves; they'd have a hard time arguing in the event of a warranty claim that they'd rotated the tires incorrectly).

So history argues in favor of it being their fault. In fairness, they were apologetic and never tried to absolve themselves of responsibility.

Regarding "Costco should have had zero problems replacing a broken stud on the spot", I wish it were so (would have saved a bit of hassle), but which expert person at Costco is going to be capable of doing this? They seemed to have shop nearby that they farmed such work out to, but this problem occurred on a Sunday...

I would almost certainly have been comfortable driving it on the remaining lug nuts for a day or two until I could deal with it. The only way I can think of that I'd not just do that would be if it were a 4-stud wheel; anything with five or more studs shouldn't have a problem with one missing.

That said... I'd have wanted to pop into the shop and personally inspect the remaining studs to make sure they weren't on the brink of failure as well.

Costco sheared off the locking socket for my weird locking lug nuts, so I daresay they're more capable of some to just uggadugga it until it (usually) works.

I've also had similar bad experiences, usually at large "chain" garages where turnover is probably high. I think it's one thing to pay a mechanic you trust to do some work on your car and quite another to leave your car at a chain garage where it will be prodded at by some kid fresh out of high school and then taken for a joy ride to "test" it.

It's also not uncommon for garages to under or over torque fasteners because they're in a hurry. My friend had his power steering pump come off the engine block while he was driving because the garage didn't bother torquing it properly after replacing it.

The last time I resorted to having someone else change the oil in my car, because I was in a place where I couldn't DIY and didn't have time to go to a relative's place to do so, I used an actual garage and not a quick-change place, thinking they'd do a better job, I provided the oil, and they managed to overfill it by more than a quart.

The people that take jobs like these are simply incompetent; if they were smart, they'd be doing other jobs.
