What is the shelf life of Coleman fuel?

It is Petroleum Hydrocarbon Naphtha, chemical formula C5-C9. Therefore it's long term storage stability should be much better than common unleaded gasoline intended as motor fuel, because it does not contain the additive mixtures normally required of motor fuels. Coleman fuel is not gasoline.

According to Coleman's web site, stored fuel is good for at least 5 to 7 years.
