Lubricating oil composition |
| abstract |
The present invention relates to a method of preventing or reducing low speed pre-ignition (LSPI) in a direct injection, supercharged, spark ignition internal combustion engine operating at engine speeds of about 1500 to about 2500 revolutions per minute (rpm) To produce a braking mean effective pressure level greater than about 15 bar, the method includes the step of lubricating a crankcase of the engine with a lubricating oil composition comprising at least about 0.2 mass % magnesium sulfate ash based on the total mass of the lubricating oil composition. |
