MPG in my sedan

[talnlnky]

my water temp swings from 184-188 fairly easy.... in the summer months I can often peak in the 190's without pushing the car hard.

40 on the highway is good... tho I think it really all comes down to where you live. Type of gas (ethanol or not, oxygenated or not) flat or hilly, windy or calm, rainy or dry, they all have effects of the mpg's.... I'd also guess that living in a higher altitude would be better due to less oxygen effecting the fuel mixture... and thus not using as much gas compared to somebody driving around at sea level.
