I've read on these forums that fuelers in southern states cheat and fill cylinders with inferior butane instead of actual propane. Butane turns liquid at -1c, which can be trouble in cold weather.
Try pouring some cold water on the regulator.
Nobody sells Butane for RV Tanks or ASME tanks in the USA. Butane is available in Mexico. Doug
That’s not quite correct, PURE butane is rare in the US, but LPG (liquified petroleum gas) sold all across North America as vehicle fuel, the stuff you buy by the gallon and put in an ASME tanks, is a blend of propane, propylene, butane, and butylene in various ratios depending on where you are the time of year.
In warmer climates or seasons butane is often a fairly large percentage since it has a higher energy density, more energy per gallon, but lower cost than propane.
The issue is when someone fills a MH tank in say south Florida then drives back to the frozen north, or fills the tank in the middle of summer but doesn’t use it up before winter.
For LPG-fueled Vehicles this is no problem since you’d burn up the butane-rich fuel long before you got far enough north for it to be a problem.
