Well, well. I've read an awful lot about the situation with Iran but never came across that piece of information before. It sounds like 'embargo' could cut two ways. I wonder how much reserves they have and how long it could take them to start hurting as well if the Straits of Hormuz were blocked.
This is a government that used duped children as mine clearers. They also utilized the human wave as a battlefield strategy. They do not care at all about the populace. After all, in two years, the Hidden Imam returns(/s). Whatever happens, it will be the will of Allah and the fault of the Great Satan, the Little Satan and the Jooooooooooooos.
However, your point is well taken and hopefully, this will fuel (intended) an increased popular revolt.
I will bet that the military and the domestic police forces will have enough fuel for whatever they need to accomplish.
