Video transcript

For summer, 5W-30 oil is generally better as it provides good viscosity at high temperatures while protecting engine components. 0W-30 can also be used, but it is more beneficial in colder climates due to its better low-temperature performance.

Questions and answers

  1. What does 5W-30 mean in motor oil?

    5W-30 motor oil indicates the oil's viscosity rating, where '5W' stands for winter (cold temperature) flow characteristics and '30' represents its viscosity at normal engine operating temperatures.

  2. Can I use 0W-30 oil in summer?

    While 0W-30 oil can be used in summer, 5W-30 is generally preferred because it maintains better viscosity and protection at higher temperatures.

  3. Why is 0W-30 better for cold climates?

    0W-30 oil flows better at very low temperatures, providing improved engine start-up protection during cold weather compared to 5W-30.
