What you get at your refill station is not likely 100% pure propane (C3H8). It is typically blend with butane (C4H10), which is a bit cheaper. The amount of butane typically depends on the time of year. One problem with butane is that its boiling point (the point where it turn from liquid to vapor) is around 34F (1C) while propane is about -44F (-42C).
In winter, if your tank contains a high concentration of butane (from a summer fill up) you may not have enough vapor to actually get it to burn !
