I'm not trying to start a political debate. And I encourage people not to. But I just want to point out, while America has had a ban on Iranian oil for some time, a lot of other countries have not.
The Iranian oil sanction doesn't directly raise U.S. gas prices, but it does drive demand for other source in countries that do use Iranian oil, which in turn raises international oil prices, which raises our prices.
Just don't be so quick to blame big oil every time
They are responsible for a lot, no doubt, but not every time is their fault :P
Also filled up at 3.83 here tonight with 91(crappy, wish I had better in my area)
