Hello All, I'm still looking around for a good Civic to buy, but i wanted to know out of curiosity as to how much the difference is in mpg between manual and auto as I've seen a nice aerodeck in auto but also a good 1.5 manual. As I know Auto's tend to use a bit more fuel, but can't find a good thread or much on google to determine this. I understand that everyone has different types of drives such as all town to mixed or full motorway.
