Motor oil lubricates every moving part inside your engine, reducing metal-on-metal friction while also helping to cool components and carry away contaminants until they're captured by the filter. Running the wrong viscosity, degraded oil, or oil that's overdue for a change is one of the leading causes of premature engine wear, increased oil consumption, and — in severe cases — catastrophic engine failure. Browse conventional, synthetic blend, and full synthetic motor oil in a range of viscosities for cars, trucks, and SUVs to keep your engine properly protected.
