Abstract:
A lubricating oil composition, a method of reducing low-speed pre-ignition (LSPI) in a direct-injected spark-ignited internal combustion engine, and a use of a lubricant composition to reduce UPI events in such an engine. Preferably, the composition comprises a detergent package comprising a borated calcium detergent, wherein the detergent package provides a calcium content in the composition of at least 0.12 mass %, based on the total mass of the composition, and wherein the borated calcium detergent provides a boron content in the composition of at least 100 ppmm, based on the total mass of the composition. Optionally, the composition comprises a first detergent comprising a calcium detergent, and a second detergent comprising a borated calcium detergent.

Claim (Index 1):
A lubricating oil composition comprising a first detergent comprising a calcium detergent and a second detergent comprising a berated calcium detergent; wherein, the first and second detergents together provide a calcium content, as measured by ASTM 4951, in the lubricating oil composition of at least 0.12 mass %, based on the total mass of the lubricating oil composition, and wherein the second detergent provides a boron content, as measured by ASTM D5185, in the lubricating oil composition of at least 100 ppmm, based on the total mass of the lubricating oil composition.
