MPGs.. More questions about MPGs than anything else IMO.
Seems to be some folks get horrible MPGs, the some get great MPGs.
I m in the great camp, with an average of 35 mpg with 70% city driving.
That is city with few stoplights and no traffic congestion.
Add in a LOT of stops at lights, and plenty of congestion, and my MPGs would drop like a STONE. (30mpg)
So that is my opinion on it.
Every stop and moving back up to speed kills fuel mileage. A LOT of stops, or even hills, and you have bad MPGs.
