I drive a 2001 Ford Focus ZTS with ~133000. I just recently filled up my coolant reservoir with 50/50 coolant. 2 days later I needed to fill it again. I went through an entire jug of coolant in 4 days. It seems to be leaking from the top of the engine and the engine runs slightly rough and has a hard time starting some days (more often recently). How bad is it doc?
It sounds like you may have a blown head gasket
That car needs to go to a shop ASAP if you want even the slightest chance of saving the engine

Make haste to your favorite reputable shop.

The OP should bear in mind that “reputable” rarely includes chain operations like Midas, Meineke, Monro, Sears, Pep Boys, NTB, or…<>…AAMCO. Go to a local independent mechanic with a good reputation.
Top of engine Could be hose leak or thermostat o-ring leak.
mrbarry, do you SEE any coolant leaking on the ground? Is there a puddle of coolant under the car? How about your exhaust, is there any white sweet-smelling smoke?
