You're in the plastic chairs under the fluorescent lights. The kid comes out holding a filter that "really should be replaced," and you already know you're about to pay extra for something you didn't come in for. You say yes because you're tired.

Oil and filter service is one of the most reclaimed DIY jobs there is, and one of the most upsold.
