Blue smoke is a classic sign of oil consumption in the engine and the major causes of these emissions are found to be worn-out piston rings, valve seals and valve guides. These causes are the resultant effect of increased oil consumption in the internal combustion engine, leading to excessive release of harmful exhaust emissions. This study is aimed at looking at the environmental impact of such increased oil consumption, by collecting exhaust samples from some vehicles that have oil consumption problems, using the Exhaust Gas Analyzer. Thereafter the pollutants are analyzed and estimated to determine their concentration and consequential impact on the environment. The result obtained showed that excessive engine oil consumed in the combustion chamber of the spark ignited engine can lead to high concentration of pollutants (NOX, CO, CxHy) released into the environment. © Maxwell Scientific Organization, 2011.
