Slick Surfaces: Pressure builds to make better motor oils
Motor oil’s protection against the wear and tear of steel engine parts takes effect only at high pressures, according to a new study.
The analysis reveals the molecular behavior of a common lubricant additive, whose mode of action had remained mysterious since the additive’s introduction in the late 1930s. Understanding the additive’s action may lead automotive engineers to design more environmentally friendly lubricants for steel as well as products especially suited for lighter, more efficient aluminum engines.
