Thin oil is generally better for winter. When temperatures drop, thinner oils flow more easily, ensuring that your engine receives adequate lubrication during cold starts. Most manufacturers recommend multi-grade oil that becomes less viscous in cold conditions, like 5W-30. The 'W' stands for winter, indicating the oil's viscosity in cold temperatures. Always consult your vehicle's manual for the manufacturer's specific oil recommendations to ensure optimal performance and protection for your engine.
