The formulated oil has a composition including a lubricating oil base stock as a major component, and at least one boron-containing compound, as a minor component. The at least one boron-containing compound includes at least one borated dispersant, or a mixture of a boron-containing compound and a non-borated dispersant. A lubricating engine oil having a composition including a lubricating oil base stock as a major component, and at least one boron-containing compound, as a minor component.
