It's interesting that the differential between avgas and mogas has
dropped from nearly $2 per gallon, to less than 75 cents per gallon.
Over time, it's averaged about $1.10 per gallon less, so either (a) the
price of car gas is being held artificially high, or (b) avgas is about
to go back up.

Mogas is starting to creep back up. 'Why' is subject to speculation, but I'd
guess the new congress is going to (perceived?) stifle production in an
attempt to lower prices.
