That guy is dumb.
The purpose of an oil is to protect, cool, and CLEAN the engine. Of course oil that has been circulating through the engine for thousands of miles is going to be darker than when it went in. Unless perhaps you have a brand-spankin' new car and it's getting it's first oil change...
But being realistic, the only time you ought to worry about your oil being dark is if you change your oil and the new stuff is immediately turned dark because your engine has so much crap in it.
