Should the New Bora use 5W30 or 5W40 engine oil?

New Bora is more suitable for using 5W40 engine oil. Here is an introduction about automotive engine oil: 1. Function: Engine oil can lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. 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 can compensate for and improve the deficiencies of the base oil, giving it certain new properties. Additives are an important part of lubricating oil.

When it comes to choosing engine oil for the New Bora, I've always preferred using 5w40 oil. Having driven Volkswagen cars for over a decade, I've found that 5w40 adapts better to various climates across China—it flows well during cold starts in winter and effectively protects engine components in summer heat. Oil viscosity directly impacts engine longevity: 5w40 maintains stability during high-speed driving or heavy loads, preventing wear; manuals typically recommend oils meeting VW502 standards, such as Mobil or Castrol's 5w40 full synthetic oils. I regularly check the dipstick to ensure oil cleanliness; never skimp on new car maintenance—using the wrong oil may increase fuel consumption or even damage parts. Based on personal experience, 5w40 proves far more reliable and reduces repair costs.

I think choosing engine oil for a new Bora depends on the specific environment. For example, I live in the south and have been using 5W40 oil all year round, which works quite well. Although the manual says both 5W30 and 5W40 are acceptable, 5W40 provides better engine protection in hot weather and reduces engine noise during high-speed cruising. I've been using Shell's 5W40 for a long time, and the lubrication effect is excellent. The key to choosing engine oil is to meet the Volkswagen VW502 specification—don't skimp and buy off-brand oils, as they can accelerate aging. Every time I change the oil, I also check the filter. Don't slack on regular maintenance; old oil can lead to reduced performance. Based on my experience, prioritizing 5W40 improves driving smoothness.

Simply put, checking the manual is the most reliable: the recommended oil for the new Bora is usually 5w30 or 5w40. I use 5w30 in cold winters for better fluidity and smoother starts; in summer, I switch to 5w40 for better protection against high-temperature wear. There isn't much difference between the two, the key is to choose genuine oil and avoid fake products. I've used several brands, and Castrol's VW502 standard oil is quite good. Regular oil changes ensure engine health; neglecting them can lead to problems.
