Should the Tiggo 3 use 5W30 or 5W40?
1 Answers
Tiggo 3 can choose 5W-30 fully synthetic engine oil. Conventional lubricants should be replaced every 5,000 kilometers or six months, while premium fully synthetic lubricants provide comprehensive engine protection under high-speed and harsh conditions. Both 5W-30 and 5W-40 oils are multi-grade oils, meaning they can be used in any season and provide engine protection. The "W" stands for winter. The lower the number before the W, the lower the viscosity, indicating better fluidity at low temperatures. The number after the W represents the viscosity at 100 degrees Celsius. A higher number indicates higher viscosity; for example, 5W-40 oil has higher viscosity than 5W-30, which indirectly indicates better high-temperature protection performance. When selecting engine oil, it is essential to consider the vehicle's usage conditions. Vehicles frequently driven in urban areas and those driven on rough roads require different oils. For vehicles frequently used for high-speed or long-distance driving, 5W-40 oil is recommended due to its excellent oil stability.
