I have an old car (skoda ovtavia 98 1.8l) it kept losing oil and coolant for years so I just checked it every time and toped it off. Recently it seems it is “gaining” oil while coolant leaks faster than usual. I don’t see any kind of smoke at the exhaust. I just don’t think oil at that temperature is supposed to steam, water temps were fine, I didn’t even drove it hard.
