Emgrand is recommended to use 5W30 full synthetic engine oil. The functions of engine oil are: 1. Lubrication to reduce wear; 2. Cooling and temperature reduction; 3. Shock absorption and buffering. Taking the 2021 Emgrand as an example, it is a compact car with body dimensions of: length 4632mm, width 1789mm, height 1470mm, wheelbase of 2650mm, and a body weight of 1255kg. The 2021 Emgrand features a MacPherson independent front suspension and a torsion beam non-independent rear suspension. It is equipped with a 1.5L naturally aspirated engine, delivering a maximum horsepower of 109PS, maximum torque of 142Nm, and maximum power of 80kW, paired with a 5-speed manual transmission.

I've been driving this Emgrand for several years, and choosing the right engine oil is crucial. The factory manual clearly recommends 5W-30 viscosity, which suits most climate conditions in China - smooth cold starts in winter and sufficient high-temperature protection in summer. The key is to check the API certification level; for newer cars, SP grade is recommended for better cleaning and oxidation resistance. My 1.5L naturally aspirated engine has been running on semi-synthetic oil with 6,000 km change intervals, which is quite economical. For turbocharged models, it's safer to go straight for full synthetic. Brand isn't too critical - domestic brands like Great Wall and Kunlun work well with good cost performance and authenticity. Never cheap out on workshop oils - a friend used substandard oil last year and ended up paying over 2,000 yuan for severe engine carbon deposits. Regular maintenance is vital; generally, change before 7,000 km.

Choosing engine oil for the Emgrand depends on specific conditions. For the first two years of a new car, it's recommended to strictly follow the maintenance manual, using 5W-30 full synthetic oil to keep the engine in optimal condition. After 50,000 kilometers, adjustments can be made based on the car's condition. For someone like me who mainly commutes short distances in the city year-round, semi-synthetic oil is sufficient and cost-effective, but for those who frequently drive on highways, full synthetic oil is necessary. The key is to buy genuine products, as counterfeit engine oil packaging can look identical to the real thing—I always stock up at official flagship stores. Remember to check the certification marks on the oil cap; SN grade is the minimum requirement. During my last maintenance, I found metal shavings in the oil pan and promptly switched to high-cleanliness oil. In summer's high temperatures, it's best to change the oil 500 kilometers earlier, and older cars require more frequent checks of the dipstick level.

The Emgrand engine isn't picky, but has some strict rules. 5W-30 is the golden viscosity - too thick increases fuel consumption, too thin offers poor protection. In northern winters, 0W grades are more reliable, starting smoothly even at -20°C. Mineral oil needs changing every 5,000 km, while full synthetic can last 10,000 km, provided you use a good oil filter. I've been using domestic full synthetic for years, saving 50% compared to imported brands. Recently discovered a trick: adding a cleaning agent before oil change and driving 10 km removes significant sludge. Always supervise maintenance - once a shop tried to use 10W-40 until I stopped them. Change oil when it turns black, don't wait for the warning light.
