Will make this update short and sweet.....

Now that construction is done on RT80, and no more winter gas, the fuel economy is now 27.45 average compared to a best average of 26 when the car was bought last summer.

So, even though a few trips showed a best of 27 mpg average for the one 15 gallon trip last year, now I am showing a weekly average of 27.45 for regular commuting (without construction backups/delays), including some strictly around town driving.

I will be doing some long highway drives from NJ to LI all through the summer. Will be interesting to see what the MPG is for those long highway trips. Bet the car averages better than 30 mpg.

Again, I have to admit that the PCM tune and Magnaflow exhaust have offset and/or exceeded any loss due to changing from 3.08 to 3.73 gears.

Your mileage may vary...

Hmmmmm. See above. AND, its time to start posting your MPG and driving habits. OK?????

And all you guys should do the same. Its not hard to write down the mileage and gallons. It helps everyone because it gives them a reference. If enough folks post their milage, maybe this thread will become a sticky.
