Use 5W-30 engine oil. Engine oil is not a universal type; it needs to be selected based on the engine type. It's important to understand the operating temperature of the vehicle before choosing the oil, especially in cold regions where anti-freeze oil is necessary to ensure normal starting and operation of the vehicle. Classification of engine oil: Generally, there are mineral oil, semi-synthetic oil, and fully synthetic oil. Mineral oil is the most common lubricant on the market, derived from the refining process of crude oil where useful substances like gasoline and aviation oil are distilled out, and the remaining bright stock is further processed and extracted. Functions of engine oil: The primary function of engine oil is lubrication. Inside the engine, oil provides lubrication to pistons, bearings, and other moving parts, reducing friction and preventing wear and tear of the components.

I've been driving a BYD F3, and I remember the manual recommends using 5W-30 synthetic oil. This grade is quite versatile, ensuring quick starts in winter and protecting the engine from high temperatures in summer. I use Shell's fully synthetic oil, which has the right viscosity for the F3's small-displacement engine, preventing stuttering and noise. The oil change interval should ideally be every 5,000 kilometers or every six months, but if you frequently drive on highways, it can be extended to 8,000 kilometers. Don't skimp on this small expense; delaying oil changes can lead to carbon buildup inside the engine and damage components, making repairs more expensive later. I also choose oils with higher API ratings, like SN or SP standards, to ensure better cleaning and oxidation resistance, preventing my older F3 from developing faults that could affect travel safety.

From a family car perspective, my F3 has always been fine with 5W-30 semi-synthetic oil - affordable and reliable. Choose big brands like Mobil or Castrol, with viscosity matching the F3's engine requirements for good protection and long lifespan. Don't delay oil changes; check every 5,000 km and replace the filter together to save money and prevent dust clogging. Regularly check the oil dipstick when parked to ensure the level stays at the midpoint, avoiding leaks and damage. Maintain proper service intervals to save costs while extending the vehicle's lifespan over ten years. After all, the F3 is a commuter car - using the right oil can even slightly reduce fuel consumption.

As a beginner driving an F3, the after-sales service recommends using 5W-30 oil as the safest choice, with moderate viscosity for easy maintenance. I opt for regular synthetic oil, costing about 200-300 yuan per change, and change it every 5,000 kilometers without skipping. Checking the oil level before starting reduces risks. Using the wrong type, such as low-viscosity oil, can cause overheating, easy oil burning, and engine damage, affecting acceleration. Regular maintenance with genuine oil ensures smooth driving with fewer issues while gaining experience.
