No, not quite. LPG stands for Liquified Petroleum Gas. Propane is an LPG, as is butane. A mix of these two gases is used as motor fuel for passenger cars. And so we also call those LPG.
Pure propane gas
Gas cylinders and tanks in the Netherlands are almost always filled with pure propane gas
. This is stored in liquid form and used in vapour form. This is because propane has a much lower boiling point than butane, so it remains in gaseous form up to 40 degrees below zero. This also makes it good for use in winter. Butane already liquefies at 0 degrees Celsius. In cars, this doesn't hurt because the engine keeps the gas warm. But if you want to take a gas bottle with you on winter sports, it is smart to make sure it contains propane gas.
