Why could your 94 BMW be using so much coolant?
It probably has a leak. Here's something to check - the radiator has a tube coming out to the reservoir, so when it gets hot and expands the coolant goes into the reservoir and should go back into the radiator when it cools, but if your reservoir has a crack and the coolant leaks out, well it's gone and can't go back into the radiator - this would cause a lot of loss of coolant.

This is a indication of a blown head gasket,unless it has been over filled or overheated.If you are getting combustion in the cooling system you will see air coming up through the coolant in the reservoir,be careful it can blow hot coolant out without any warning.Most shops have a tool that will detect combustion gases in the coolant,it should be a inexpensive test.
