Mine went from 28.3 to 25.7. Damn heat.

 

Just curious....
Turbo or Supercharger?
Running the A/C a lot?

 

S/C with the a/c on.

 

Back to shitty mileage now that it's cold. I was able to average about 32-34 over the warm weather months. Luckily gas is way cheaper now

April 29.55 mpg
May 31.78
June 32.24
July 34.09
Aug 33.39
Sept 32.49
Oct 31.88
Nov 30.76

I pump on average of about 10 times a month so give or take 100 gal/month.
Since I purchased the car last December I have an overall average of 30.79 and racked up almost 40k miles. Just put on new Toyo Proxes 4 Plus tires because I caught a nail in my tire and had a flat. I was planning on getting all new tires next month anyway.

 

These are all actual calculations. My DIC is always 1-3mpg more than actual.

 

Since when does the DIC use fuel injector pulse width as a measure of how much gas your consuming? I was under the assumption it was a calculation based on the rate the fuel level sensor drops vs miles driven/speed.

 

I have no idea how the DIC calculates mpg. I just always compare the DIC MPG every tank with the actual mpg I am able to calculate (miles driven divided by gallons pumped)
