Should the Tiggo 3 use 5w30 or 5w40 engine oil?
2 Answers
Tiggo 5 can use 5w30 engine oil. The 'w' in the engine oil model stands for 'winter,' indicating that the oil can be used normally in winter. The number before 'w' represents the low-temperature flow performance, and the number after 'w' represents the high-temperature viscosity of the oil. Relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It lubricates and reduces friction, assists in cooling, seals against leaks, prevents rust and corrosion, and provides shock absorption for the engine. It is known as the 'blood' of a car. 2. Composition: Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, giving it new properties, making them an important part of lubricating oil.
I think choosing engine oil depends on specific driving conditions. The Tiggo 3 manual generally recommends 5W30, especially for new cars. 5W30 has good low-temperature fluidity, reduces cold-start wear, and improves fuel efficiency. However, in the cold northern winters, 5W30 can still perform normally at -30°C. If you frequently drive on highways or your car has over 60,000 kilometers, the piston clearance in the engine increases, and switching to 5W40 provides better high-temperature protection. I have an old Tiggo with 100,000 kilometers, and I always use 5W40. The most important thing is to listen to the engine; if you feel rough performance or a noticeable increase in fuel consumption, it's time to check if the viscosity is suitable.
