Hi everyone, I currently have a 2009 Honda Civic 4dr, and I recently went in the Honda dealership in my town to get an oil change. They tell me after the oil change, there's an oil leak, and they need to put some type of glue, which I'm looking at about $300.

Am I being ripped off, or something? I wanted to do my due diligence before I just hand over $300. Thanks to anyone in advance!
