What type of engine oil should be used for Geely Free Cruiser?

It is recommended to use Mobil 1000. This type of engine oil is of good quality. Automotive Engine Oil: Automotive engine oil is a lubricant used for carburetor-type engines in cars, tractors, motorcycles, or other gasoline-powered machinery. It is produced from petroleum lubricating oil distillates or deasphalted residual oil, through processes such as dewaxing, sulfuric acid (or solvent) refining, and clay treatment, with a certain amount of additives added. Engine Oil Standards: The viscosity and grade of engine oil are the determining factors for its proper use. Internationally, the viscosity and quality grade of engine oil are classified using SAE's viscosity classification method and API's quality grade standards. Generally, the SAE grade represents the viscosity grade of the oil. Summer engine oils are not indicated by letters but directly by numbers, which include 20, 30, 40, 50, and 60. These numbers indicate the maximum temperature at which the oil is suitable for use.

The Geely Free Cruiser is quite particular about engine oil. Having driven this car for several years, I follow the manual's recommendation: the standard specification is 5W-30 full synthetic oil, with an API rating of SN or above for better lubrication and fuel efficiency. Remember to change it every 5,000 kilometers or six months—never skip or use the wrong type, or the engine will wear out faster. In cold winters, 5W-30 ensures easy starts; in hot summers, a slightly higher viscosity like 10W-40 works, but avoid overly thick oil. I buy genuine oil from the 4S shop, as cheap online purchases risk counterfeit products that can damage the engine—repairs are costly. During oil changes, check the oil filter and ensure the level is at the midpoint on the dipstick. Overfilling causes leaks, while underfilling leads to cylinder scoring. Adopting these habits can extend your car's lifespan.

The Geely Free Cruiser is quite suitable with 5W-30 engine oil. Based on my experience from car forums and real-world driving, this viscosity works well for most seasons. An API rating of SL or above is sufficient, but upgrading to full synthetic is recommended for better protection. For older vehicles or frequent high-speed driving, 10W-40 can be used to increase viscosity and prevent insufficient thickness at high temperatures. The key is to change the oil every 5,000 kilometers, as oil quality directly affects engine noise and fuel consumption. Don’t forget to replace the oil filter as well—low-quality oil can lead to carbon buildup. I recommend buying branded oil from reliable shops for a cost-effective solution. Also, when checking the oil level, ensure the engine is level. Add a little if it’s low, but don’t exceed the upper limit.

As a Geely Freedom owner, I use 5W-30 full synthetic oil, as advised by the mechanic, which is suitable for daily driving. The manual states that lower viscosity ensures quicker starts in winter and no overheating concerns in summer. Change the oil every 5,000 kilometers—it's affordable but protects the engine well. Avoid cheap, low-quality oil; I once tried saving money with a budget option, and the car's noise increased noticeably. During oil changes, check if the oil level is within the standard range by simply looking at the dipstick marks. Regular maintenance as per the manual is better than costly repairs.
