Your piston rings are most likely worn out. you'll have to do an engine overhaul or just hire a mechanic to do it. It could also be excessive wear to the cylinder walls and might need to be "Honed"

Keep topping up coolant on Renault there is no leak?
If coolant isn't leaking externally then it has to be leaking internally. A leaking head gasket or cracked head may be the problem. If this is the case, as it gets worse more coolant will enter the combustion chamber or engine oil. Either way you will be able to determine as it gets worse. There will be white smoke from the exhaust. May be intermittent. This is if coolant is leaking into combustion chamber. If leaking into oil, you will notice that the engine oil will have a brown/milky look to it as you check the oil level on the engine oil dipstick.

Your 2004 Buick Rendezvous is leaking a black liquid from Cadillac Converter?
"Catalytic Converter" not cadillac, lol. The black liquid is carbon soot mixed with water from condensation in your exhaust. The carbon soot is from the oil that lubricates your engine, it also gets small amounts in the combustion chamber, thus when your fuel/air mixture ignites in the (combustion) chamber, the oil (with carbon in it) is burned off and exits with the exhaust.
