Discover the differences between 5W-30 and 10W-30 oil and learn which one suits your climate and vehicle needs best.

340 views

10W-30 oil is thicker than 5W-30 at lower temperatures. The first number (5W or 10W) indicates the oil’s viscosity at cold temperatures, with a lower number meaning thinner oil. Both oils have the same viscosity at high temperatures (30). Choose based on your climate: 5W-30 for cold climates and 10W-30 for warmer conditions.

FAQs & Answers

  1. What does the 'W' in oil ratings mean? The 'W' stands for winter and indicates the oil's viscosity at low temperatures.
  2. Can I use 10W-30 instead of 5W-30? Yes, but it's best to choose based on your climate; 10W-30 is thicker in cold temperatures.
  3. How does temperature affect oil viscosity? Oil viscosity changes with temperature; lower numbers indicate thinner oil suitable for cold conditions.
  4. Which oil is better for hot weather? Both 5W-30 and 10W-30 have the same viscosity at high temperatures, but 10W-30 is often preferred in warmer climates.
