You may have noticed that the 2008 Pontiac G8 GT was absent from this week's monthly fuel economy summary. There's no sinister hidden meaning here. I'd simply used it as my airport car for a trip overseas and was unable to cough up the data.
So here it is, your Pontaic G8 GT lifetime fuel economy summary through June, 2009.
Best tank: 24.0 mpg
Best Range: 351 miles
Worst tank: 12.0 mpg
Lifetime average: 17.6 mpg
For comparison, the official EPA combined fuel economy rating for this car is 18 mpg, so we've pretty much nailed it.
The average mpg figure represents 23,783 miles of driving. In that time our G8GT burned 1,354 gallons of fuel. That represents about $3,000 to $3,500 at current prices.

Pretty solid for a V8 powered full size sedan.

I'm at 21.5 / 13.8 / 17.3 over 9,102 logged miles.
This afternoon I replaced the driver's left turn signal bulb. Step 1: Remove the airbox...

byehl, I thought the first step was to cut a hole in the airbox...

The last step was installing the Vararam. Not sure what to replace the fuse block with when I have to do the other side...

I'm sitting at around 17-18.5mpg with the A/C on in my mixed stop-n-go/city/highway commute. When it was cool enough to go without A/C, I was at about 19-20mpg. I haven't done a real highway trip, but I did an hour or so sting on the highway. With a reset computer, I averaged 24.0mpg with the A/C on at 69mph average. The only other V8 car I ever owned got 20mpg once, without A/C, at a steady 65mph. I don't miss that car.
