Wow - probably the best can out there; it locks closed and I feel save when I am transporting this; I did upgrade to the Atlantic British Ltd. spout as recommended elsewhere. Storing gasoline in metal will keep that gasoline a lot longer - be sure to use STABIL or a similar product and be sure to rotate the stored gas (consume it in your vehicle, and refill) periodically. I have kept gas easily for two years in metal cans such as this (and I don't really know how long is too long) for use in an emergency generator during storms.
