02 is affected by the oil consumption. A bad 02 does not make an engine burn more oil, unless the gas consumption is way up too! If mileage has greatly declined, check the fuel pressure regulator, if there is any gas in the vacuum line, replace the regulator. Check the oil on the stick, smell any gas in it? If so change the oil and filter with the regulator. Gas can and will wash the oil and compression rings on the pistons, allowing oil to pass into the combustion chamber.
