Viscosity Explained: 10W and 40

Engine oil viscosity refers to its resistance to flow. The “10W-40” designation indicates a multi-grade engine oil, designed to perform across a wide range of temperatures.

• 10W (Winter Viscosity): The “W” stands for winter. The number preceding it (10) indicates the oil’s viscosity when cold. A lower number means the oil is thinner at low temperatures, allowing for easier cold starts and faster lubrication of engine components, which is critical for reducing wear upon ignition.

• 40 (Hot Viscosity): The second number (40) indicates the oil’s viscosity at operating temperature (typically 100°C). A higher number here means the oil maintains a thicker film at hot temperatures, providing robust protection against metal-on-metal contact under heavy loads and high operating temperatures.

This multi-grade capability makes 10w-40 oil a popular choice for vehicles operating in varied climates, offering excellent protection from freezing mornings to scorching afternoons.

The ‘Super’ in Super Oil: Additives and Performance

When you see “super” associated with engine oil, it often implies a blend of advanced additives designed to enhance performance beyond basic lubrication. These additives are crucial for the overall health of your engine.

• Detergents: These prevent sludge and varnish buildup, keeping your engine clean.

• Dispersants: They hold contaminants in suspension until they can be filtered out, preventing them from settling and forming deposits.

• Anti-wear Agents: Such as zinc dialkyldithiophosphate (ZDDP), these create a protective film on metal surfaces, reducing friction and wear.

• Corrosion Inhibitors: They protect internal engine parts from rust and corrosion, especially important in environments with high humidity or short trips.

• Viscosity Modifiers: These are polymers that help the oil maintain its viscosity across temperature changes, which is key to the multi-grade performance of 10w-40.

These specialized components are what make a “super” grade oil superior in protecting your engine.
