Geely's new Emgrand uses engine oil with the specification 10W-30. Here are the details about engine oil specifications: 1. Engine oil, also known as engine lubricant, has a density of approximately 0.91×10³ (kg/m³). It lubricates the engine, reduces friction, assists in cooling, seals against leaks, prevents rust and corrosion, and acts as a shock absorber. It is often referred to as the 'blood' of a car. 2. Engine oil consists of base oil and additives. 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, providing new characteristics and making it an essential part of lubricating oil. 3. 10W-30 is the SAE standard viscosity value for engine oil. The 'W' stands for WINTER, and the number before it indicates the oil's flow performance at low temperatures—the smaller the number, the better the starting performance in cold conditions. The number after the 'W' represents the oil's stability at high temperatures (i.e., its resistance to thinning)—the higher the number, the better the oil's high-temperature stability.

I've been driving an Emgrand for several years and generally recommend using 5W-30 full synthetic engine oil. This viscosity grade suits most Geely Emgrand engines well, especially the 1.5L engine which runs more smoothly with it. From experience, oil viscosity selection is crucial - 5W-30 performs well across various climates, enabling quick cold starts in winter while maintaining proper thickness in summer heat to minimize component wear. I've also observed that synthetic oil extends drain intervals to approximately 7,500-10,000 km, reducing maintenance costs. Always choose reputable brands like Shell or Castrol to avoid counterfeits, and check API specifications (SN grade suffices) when purchasing. Regularly inspect the dipstick to ensure proper oil level and that the oil hasn't turned dark black - this prevents engine aging and ensures driving peace of mind. While you should adjust if the manual specifies special requirements, this basic recommendation rarely goes wrong.

When using the Emgrand, I prefer 5W-30 oil for its cost-effectiveness and durability. Initially unsure, I consulted technicians who confirmed this grade suffices for daily driving, especially city commutes—it reduces engine noise slightly and improves fuel efficiency slightly. It performs well in areas with significant temperature variations, like hot southern summers or cold northern winters, eliminating the need for frequent grade changes. I use Mobil or Great Wall brands, which offer reasonable prices and decent quality. Oil change intervals are around six months or 7,500 kilometers, adjusted based on road conditions—earlier changes if more highway driving. Always replace the oil filter during changes to prevent clogs, simplifying maintenance and extending the car's lifespan. Monitor oil levels to avoid overfilling, which can impair performance. Personally, I believe timely oil changes are crucial.

The Emgrand is suitable for using 5W-30 synthetic oil. Simply put, it provides balanced viscosity and adequate engine protection. I checked the manual to confirm this recommendation and avoid mistakes. Choosing the wrong oil type may damage the engine, increase friction or cause oil burning, affecting power and lifespan. Change the oil regularly, such as every 5,000 kilometers, to ensure fresh oil quality—don't delay too long. Drive gently, and the engine will run smoother after an oil change. Basic maintenance isn't difficult; you can do it yourself or go to a small shop.
