Thinner oil is generally better for winter. Cold temperatures can cause oil to thicken, making it difficult for the engine to start. Using a thinner oil, such as a 5W-30 instead of a 10W-30, ensures better engine performance during cold starts. Always consult your vehicle's owner manual for the recommended viscosity.

FAQs & Answers

  2. How does oil viscosity affect engine performance? Oil viscosity influences how well oil flows and provides lubrication, directly affecting cold start performance.
  3. Can I use thicker oil in winter? Using thicker oil in winter can lead to poor engine performance and starting difficulties, so it's best to stick with thinner options.
