Why would a small currency market have a harder time to buy oil? My first guess is that it should depend on the competetiveness of the industry in the small currency market and the industry and infrastructure efficiency. Is there something inherently bad with having a small currency such as SEK?
"Infrastructure efficiency" was what I was thinking, perhaps I over-generalized using EM.  For instance, I read somewhere that the average speed of a truck in India was something like 25 mph.
I think when gas prices hit $6/gallon the US should adopt the metric system.  It might not be so overwelming.  $1.60/litre is not so frightening and the controversy will take away from the real issue.
I like the trickery...u know it would work too that's the sad part.
That is almost exactly the Swedish petrol price with taxes.
People complain about it but they do not revolt.

Go for it, every killing of a "funny unit" is a good kill.
