I am on Yelp and have a thread going about this. My Yelp friends are stating that gasoline stations do not differ whatsoever in what they offer. Essentially, all gasoline comes from the same place apparently in my city (apparently). Some say to get premium grade gasoline for my 2001 Camry because I will get better millage from it. Others say premium gasoline is no better than regular and a waste of money. Do any of you have any good, deep knowledge about cars and can address this issue? Thanks!
