My oil was overfilled. How much is too much?

Obviously, they just dumped the oil in and didn't even bother checking the dipstick, dipsticks!

Doing your own oil changes is the best way to ensure that you get the job done properly. Plus, it's rewarding and saves a lot of money, especially since you can grab a high quality, inexpensive jug of synthetic oil and a filter from any Walmart.

Wow, 2 drains? I have never owned a car like that or even considered that possibility. It just goes to show you though that places that specialize in something as trivial as an oil change can screw it up.

I guess the benefit is that if they screw it up and it causes a catastrophic failure they can be held liable (though probably difficult to prove). If I screw up it's all on me, but I'll still keep changing my own oil because I'm cheap. Lol.
