Summary:

Emissions system durability may be influenced by many engine oil formulation variables. Previous studies have suggested that emissions system durability is optimized by high metal/phosphorus ratios. Reducing the level of phosphorus in the engine oils has also been suggested as a means of prolonging the efficiency of the catalytic converter. This paper explores engine oil formulation variables which may influence the efficiency of the emissions system. Phosphorus type and amount are examined as potential catalytic deactivators, as well as detergent metal interactions with the phosphorus. Dynamometer and over-the-road test data are presented which suggest that the volatility characteristics of the phosphorus component in the engine oil may influence the degree of catalyst contamination. To explore fully the many variables, however, will require an emissions performance test
