21 MPG whats wrong

[frownonfun]

My mileage has never been all that great either. But I think the city of Odessa (since it's an oil town) actually constructs everything in such a way that people use as much gasoline as possible. Ok maybe that's a stretch but seriously the civil engineers around here must be bottom of the barrel because the traffic here is a nightmare and shouldn't be for a town of this population. Maybe you are in a town that doesn't have anything set up very well either. Just try driving a Tundra that gets 12mpg around for a while and then you'll love your 21mpg.

Like seriously if there is an intersection in this town without a stoplight i'm sure they are working on putting one up right this very moment. And god forbid you ever make more than one green.

I changed my rims and tires just like everyone else, except I used a wheel diameter chart to determine the tire size and aspect ratio so as to keep the diameter within 1% of the stock diameter so that my odometer continues to give accurate readings.

Good job you brought this up... i didn't realize that.

Ever since I changed to 17' Cooper S rims, my speedo is slower than actual speed. Therefore the distance counter must be also slower (less), that would make sense to the loss mileage!
