My oil was overfilled. How much is too much?

Yes, I get your frustration. Certainly, you'd expect to have a Toyota dealership do the job correctly. Years ago I owned a 5.0 Mustang LX. The car had a double hump oil pan with two drains. It wasn't a dealer oil change but they only drained one side of the pan and then refilled with the factory spec amount. I was significantly overfilled as a result. 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.
