Any way to aggregate MPG by gas attributes?

[kalos7k]

IE group MPG by different gas stations, fuel type, location, etc, across the same type of car in the same region.

That's something we're working towards.
We've only recently started asking for this data and it's still optional. As we collect more, we'll be able to figure out creative ways to put it to good use, like you mentioned.
