Wow, if it's 30-minute test sessions at CoTA, then the fuel mileage is really good. That comes to about 13 minutes per gallon on a track that I can reasonably compare to The Glen regarding WOT time.
At The Glen, my car gets roughly 9.4 - 9.7 minutes run time per gallon.
So, the question to Mike is -- did you burn 2.3 gallons for full 30-minute runs at racing speed?
If you want to compare apples, limes, and tomatoes... At TWS a couple years back I ran a 2:01.6 w/ 82% time on full throttle, and at CoTA last Wednesday I ran a 2:41.8 w/ 75% time on full throttle. No idea how much time the Gen3 spends at full throttle running laps at CoTA, but that might tell you a little something about the nature of the track. Those are just average test laps from the middle of the pack on my ~5 year old engine. If you like spreadsheets maybe you can make something out of that
For sure, it's going to take a lot more real world data scraping to come up with a true fuel mileage estimate/average. As a portable rule of thumb, I've used 10 minutes run time-per-gallon as an average for the 1.9-liter engine. Obviously, the more WOT time (say WOT?) the more fuel burned.
For instance, at Pocono with its long straights the number gets down close to 9 minutes. At New Hampshire, where we never use 5th gear, it starts banging up into the 11-minutes range. Lime Rock comes in at roughly 10 minutes.
