Stacker, there is no doubt that engine coolant (and as a result, the LPG regulator) temp makes a lot of differneces in how much "goop" cracks out of LPG fuel. there is also a pressure problem that can be introduced when a gravity feed tank fill process is used outside in low temps, and then the filled LPG tank brought into a warm building and allowed to reach "room temp".
there is no government body that checks to be sure the LPG that is claimed to be hd-5 really is, as far as I know.
