a good Honda 4 cyl engine will push out a bit of blow at idle rpm which will disappear at about 1800 rpm. Its very normal. If in doubt check the PCV valve for functioning. Replace or clean as necessary.
if you dont have oil consumption then what you are seeing is not oil burning. Most probably steam as the weather is getting colder - thats normal too. Finally to ensure long engine life - make sure that your engine always works at normal temperature, not dead cold.
