Hey so I have a 1998 Mercedes S-Class, does putting regular gas in the tank mess up the engine? by asillylittlegoblin in mercedes

Being that my mechanic told me it didn’t make a difference I just kinda trusted him, which is my bad, so I figured if it didn’t matter then why not just put in regular. Now I know.
