Those of you that fill up with premium have probably noticed the increased price spread between regular and premium. Back when gas prices were high, the difference used to be around 20-25 cents per gallon. Now it's more like 50 cents, and I have seen stations where premium was $1 per gallon more than regular.
I thought this was some kind of price gouging ("people with expensive cars shouldn't complain about expensive gas" mentality), but this article blames it on shale oil that is not good for making higher octane fuel...

It turns out that the type of crude drawn from shale formations is rich in low-octane chemical components and therefore far easier to refine into regular unleaded. Foreign-sourced oil, such as the kind that OPEC producers supply, is easier to turn into high-octane premium.

Any truth to this?
