Don't go by what it shows on the cluster... keep track of your own numbers through a few tanks, and see how that compares.

And yes, it's VERY hard to keep your foot out of it!

I do about 18.9 to 20.2 in my mixed commute to work - mostly freeway.
I can get a bit better (22.2) if I drive ultra-conservative.
This running 92+ octane - I can get better on 100 octane with the GIAC "race" gas program, but the per gallon cost negates any advantage.

Based on my last 5 fill ups, I'm getting an average of 18.01 miles to the gallon. From those five, my highest was 20.04 mpg, lowest was 15.52 mpg.

Not generally as long as the the overall diameter is the same as stock. Unless your rim and tire package is significantly different in weight.

It's the tread width (and therefore the size of the contact patch) that makes the biggest difference. I took about an 8% hit in mileage going from my 195s to 225s on my Jetta. Weight can be a contributing factor, even aerodynamics... but road friction is the biggest difference. Of course, if the overall wheel/tire circumference is significantly different from OE spec, than the values reported by your speedo, odo, etc. would be off as well, affecting any un-corrected calculations by you or the car.

I made a new record a week ago! 8.1 l/100km which is 29.04 mpg (US) and 34.87 mpg (Imperial)

Not bad, eh?

I have been getting 25 MPG the last two weeks, in mixed driving. I know it could do better on a different route though.                                                                           Do you think Mike has the tourque convertor symtems ?
