Abstract (en)
[origin: EP1760137A1] The present invention is directed to a low sulfur, low sulfated ash and low phosphorus lubricating oil composition for low emission heavy duty diesel engines comprising (a) a major amount of an oil of lubricating viscosity and (b) at least 2 weight percent of an anti-wear additive composition comprising a metal salt of a Mannich condensation product based on the total weight of the lubricating oil. The present invention is also directed to a low sulfur, low sulfated ash and low phosphorus lubricating oil concentrate comprising (a) an oil of lubricating viscosity and (b) at least 2 weight percent of an anti-wear additive composition comprising a metal salt of a Mannich condensation product based on the total weight of the lubricating oil.
