Hi Torsten

Most fuel stations within towns sell only diesel and leaded fuel, unleaded fuel tends to be available in fuel stations on the way in/out of town. The modern Afriquia stations tend to be the ones that always have unleaded.

However once you get south of Tan Tan and also within Western Sahara there's no more unleaded, it's leaded only. On the plus side however the price of the fuel is about half that of the rest of Morocco.
