5W30 is thicker than 0W30. The '5W' and '0W' ratings refer to the oil's viscosity at low temperatures. The lower the number before the 'W', the better the oil's performance in cold starts. Hence, 0W30 is thinner in cold conditions compared to 5W30.

FAQs & Answers

  1. What does the 'W' in 0W30 and 5W30 stand for? The 'W' stands for 'winter,' indicating the oil's performance in cold temperatures.
  2. Is 0W30 better for cold weather than 5W30? Yes, 0W30 is designed to perform better in colder conditions due to its lower viscosity.
  3. Can I use 5W30 instead of 0W30? It depends on your vehicle manufacturer's specifications. Always check the owner's manual before switching oil types.
  4. What is viscosity in motor oil? Viscosity measures the thickness of the oil and its ability to flow, which is crucial for engine performance.
