I’d start by saying I’m not crazy, but of course you’d expect me to say that.

I could swear that a year or two ago I read an article that referenced the differnce between the gasoline you buy at the big chains like Exxon and the gas you buy at discount chains like Wal-Mart or your grocery store. From what I remember, the gas from the chains was processed differently such that it burned cleaner and thus was better for the environment and led to better gas milage.

I’ve been looking for something to back that up and am coming up with zilch. IS there any difference? One can usually save $0.05 or more a gallon at one of the discount chains, so I’m curious as to whether there’s a documented difference in the quality of gas. Help me interweb, you’re my only hope!
