450 cause i drive like a granny

and i get around 500+ on the highway

 

Yeah, one of them is wrong... I just went with info I googled.. the one I found definitely is starting to sound high

 

Wrong? Not necessarily... Keep in mind miles per US gallon is going to be 18% lower than miles per imperial gallon.

When I boast that I got 106mpg once in a 9.6km combined city-highway drive in an Insight, I converted to Imperial gallons to get the extra-ordinarily high number... Otherwise it would have been a fairly pedestrian 89.9mpg.

Of course if one drove like that normally, one would want to drive screws into his own forehead for a little excitement...

 

hm.. yeah that's true. Oh well I'll stick with my calculations. That way I can track if I'm getting better or not. Oh btw Gary, I'm bringing my car down next monday for your expertise! Been driving it for at least a month since I brought it up from the states and didn't go through a check yet. haha.

 

Ah thats where I messed up... different unit of measurement. I forgot that the US gallon is a bit different
