Honestly, I never heard of a "green" oil change. But my pals over at Mike's Automotive in Somerville say they're offering one now, and I believe them.

Yes, I could be falling for a heinous act of greenwashing, but I've been relying on this business for 17 years, and if they're lyin', I'm a complete fool and you probably would have to question anything I say. Nevertheless, I trust them.
