How does synthetic oil differ from conventional motor oil?

Synthetic oil is man‑made and more highly refined, so it protects your engine better and lasts longer than conventional oil.

Key differences

• How they are made: Conventional oil comes from refined crude oil, while synthetic oil is chemically engineered so its molecules are more uniform and contain fewer impurities.
• Stability and protection: Synthetic oil is more stable, resists degradation, and better protects against wear, sludge, and deposits, especially in modern engines.
• Temperature performance: Synthetic flows more easily in cold weather for safer start‑ups and stays thicker at high temperatures, so it protects the engine better in winter, summer heat, towing, and hard driving.
• Oil change interval: Because it breaks down more slowly, synthetic oil can often safely go longer between oil changes than conventional oil, depending on your vehicle and driving.
• Cost: Synthetic oil costs more to manufacture, but its longer life and better protection can help reduce engine wear over time.
