There's a lot of information running around - but the thing is, it is scientifically proven that some gasoline brands burn cleaner than others. In fact, *every* major maker in the US *imports* Chevron gas (current cleanest-burning, but not sold anywhere near Detroit) to get their cars to pass the EPA tests.
