What type of engine oil is suitable for BYD L3?

5w-40 engine oil viscosity. Here is some knowledge about engine oil: Introduction: Engine oil, also known as engine lubricant, with a density of approximately 0.91×10³ (kg/m³), serves multiple functions for the engine including lubrication and wear reduction, auxiliary cooling, sealing against leaks, rust and corrosion prevention, and shock absorption. It is often referred to as the 'blood' of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricants, determining their fundamental properties, while additives are used to compensate for and enhance the shortcomings of the base oil, providing additional performance characteristics. Additives are an essential part of lubricants. Requirements: As a type of machinery, an engine has common requirements for lubricants similar to general machinery, such as appropriate viscosity, certain levels of oxidation resistance, wear resistance, corrosion prevention, and viscosity-temperature properties. However, engines are also a special type of machinery, and their requirements for lubricants have unique aspects.

As someone who has long been concerned about car maintenance, I believe the BYD L3 is best suited for 5W-30 full synthetic oil. Having driven similar models for years, this oil performs stably in most temperatures and ensures quick winter starts without damaging the engine. In the hot summers of southern regions, you might consider 10W-40, but always check the vehicle manual recommendations to avoid voiding the warranty. I recommend checking the oil level every 5,000 kilometers and replacing it promptly when dirty—brands like Shell or Great Wall work well. Choosing the right oil isn’t just about convenience; it improves fuel efficiency, reduces consumption, and saves money in the long run. Don’t forget to clean the filter when changing the oil to keep overall maintenance costs lower.

I enjoy tinkering with cars in my spare time, and I have experience choosing engine oil for the BYD L3. I recommend using a 5W-30 synthetic type because its viscosity is just right. It won't cause startup issues in cold weather or become too thin in hot weather. When changing the oil yourself, first check the dipstick to confirm if the level is below the standard, then purchase a brand that meets API or ISO certifications, like Mobil, to ensure performance. Remember, engine oil affects power smoothness and engine lifespan. If you drive in congested city traffic, it's even more important to change the oil on time to extend component life. Overall, making the right choice can save you from costly overhauls, and a few simple checks can keep your beloved car in good health.

From my perspective, the BYD L3's preferred engine oil specification is 5W-30 synthetic oil. This is designed for daily driving needs, ensuring smooth ignition even at -30°C in winter to avoid cold-start issues. If unsure, consult the user manual or ask a professional shop to confirm the engine specifications. When changing the oil, be cautious not to let the oil temperature get too high, and the quantity required is approximately 4 liters. Regular maintenance ensures proper lubrication and protection of the system, reducing the risk of malfunctions. Choosing the right oil can also reduce noise, making the drive quieter and more comfortable.
