Gas Mileage Increasing?

who is right? are you doing your own calculations with total miles/total gallons purchased?

14-16 are the numbers I see on my dash for everday mixed Hw/City driving just before I fill up(normally a little over 3/4 tank). The manual calculation miles/gallons pumped is close to what the dash states. If you have read what I said earlier about the 20-18, its pure highway miles. Once I exit off the highway and get to my destination, it usually drops to 18 fairly quickly.

I'm managing roughly 16MPG with 2150 on the odo, but I attribute most of that to that thing called "intoxicating engine noise". 60% highway, 40% rual.
I hope things will improve as yours did![Smilie](https://g35driver.com/forums/images/smilies/smile.gif)

in your case maybe. probably its just a hit-or-miss thingy with the new Gs. The discrepancy is too great. For me i grandma-ed the pedal in itsy bitsy increments and still got bad mileage. I'm already at 4k miles. Hopefully there is a miracle break-in number that I haven't got to just yet.

maybe it has to do with what percentage you drive hwy, and how fast you go on the hwy.
last time i was in boston, i don't remember the hwy being too wide, or cars driving particularly fast.

For kicks, on my non Infiniti car, I wanted to see how accurate the mpg computer was, so I filled up, punched the reset, and the trip odometer. Upon next fill-up, I did the above formula, and compared it to what the computer showed. No joke, the computer was accurate right down to the tenth. So the computer is really using what fuel was consumed vs. distance traveled and showing an accurate number...

I've recently noticed a change but I thought it was because I switched to 94 Octane rather than 91. This extended the kms in the 500's
Thanks

The last two days I'm avg 27 mpg @ 70 mph. All conditions are the same. It appears that the full mapping has changed after the 3500 mile mark. This is the point that the first oil change happens at. From this point on the computer must lean out the motor to get better gas mileage. Has anyone else noticed this?
