For those of you with bad gas mileage. I don't know where you live, but I have noticed that the weather plays a big factor in the mileage. I was driving a GLS V6 as a demo and was getting about 24mpg with combined city and highway, and lots of sitting in traffic. Once the weather got stupid cold, gas mileage went down to about 19mpg. When the car is cold, more gas is dumped into the engine to aid in warming the engine up. I also noticed an increase in exhaust fumes when it is real cold as well, indicating the rich condition. I am now driving an LX as a demo, and the mileage is the same 19mpg as it was in my GLS. I'm guessing the poor mileage is due to the cold weather. I will be in this demo until about March, so we'll see if it gets any better when it warms up. If you live in a colder area, this could be one explanation. If you're in a warm environment, I don't have an explanation.
