Hello,
A correct fuel and air ratio must be maintained for optimum performance, economy and emission requirements. This balance is monitored by oxygen sensors in the exhaust system which provides feedback information to the car's computer (PCM-ECM). The computer then makes adjustments in real time to the fuel being added at any given RPM or load demand. When parts of the sensing or fuel delivery system malfunctions it can produce black smoke from the exhaust pipe.

As you can imagine engine oil is present all welcome throughout the engine as it lubricates internal parts. The combustion chamber is the exception. This chamber must stay as oil free as possible to help allow the fuel to burn as clean as possible
