I have my new '13 GS LS3 for 5 days now, and have driven it 107 miles. Following the break-in procedures, I've not exceeded 3,500 rpm.
All of my driving has been around town, in stop & go traffic, and occasionally cruising in 5th gear, at 45 mph, for brief periods of 5 or 6 miles.
The car is showing me 11.7 mpg. Realizing that the engine is still new, and tight, I'm guessing that I can expect about a 10 ~ 15% increase after it's broken in, is that reasoning correct?
If so, it would bring me to about 13 mph. Still pretty bad.
There are many threads devoted to discussing gas mileage, but they all place the emphasis on the best possible extended highway mileage.
I have not found any comparisons of normal every day around town driving. Don't misunderstand. I didn't buy this car expecting good gas mileage. However, I did expect to be around the 15 ~ 16 MPG mark set by GM.
I was wondering what others are experiencing with the same car, in similar around town driving?
Thanks in advance for your input.
