What type of engine oil is suitable for the Changan CS55?
3 Answers
Changan CS55 can use synthetic engine oil with a density of approximately 0.91 x 10³. The recommended oil quantity is around 4 liters. Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve the shortcomings of the base oil, providing certain new characteristics, making them an essential part of lubricating oil. The Changan CS55 is equipped with a turbocharged engine. Its headlights feature a sharp design style, and the polygonal grille is paired with silver trim, giving the front of the car a powerful appearance. The vehicle dimensions are 4500mm in length, 1855mm in width, and 1690mm in height, with a wheelbase of 2650mm, making its body size moderate in its class.
When it comes to choosing engine oil for the Changan CS55, I believe the most crucial factors are the engine requirements and the manual recommendations. It generally suggests using full synthetic oil with a viscosity of 5W-30 or 5W-40, as this middle-ground viscosity is the safest option—avoiding oil that's too thick (which can affect fuel consumption) or too thin (which might lead to leaks). Opt for major brands with API SN or SP ratings, such as Castrol or Mobil, and never skimp by buying low-quality products from small manufacturers. From my experience, full synthetic oil offers superior performance with an oil change interval of 8,000 to 10,000 kilometers, helping to reduce carbon buildup and wear, especially providing strong protection for turbocharged engines. In colder climates, 0W oil ensures quicker starts. Regularly check the oil level and don’t delay oil changes too long, or else engine repairs could cost a fortune. In short, first review your owner’s manual to confirm the specifics, then choose a compatible product for worry-free driving.
Over the years with my CS55, I prefer changing the engine oil myself and recommend 5W-30 full synthetic as the basic choice. Viscosity isn't something to pick randomly—too thick, and acceleration slows with higher fuel consumption; too thin, and leaks become likely. Official data shows 5W-30 as the sweet spot. I favor the Castrol Magnatec series, which includes anti-wear additives, resulting in quicker engine response and reduced noise. Don’t overlook the API rating when choosing oil—SP grade is optimal. DIY oil changes save on labor costs, getting the job done for just a few hundred bucks. Remember to pair it with a quality oil filter, not just the cheapest OEM option. In colder environments, 0W oil can make starting easier. Stick to an 8,000 km change interval—don’t exceed 10,000 km—to keep the car stable and cost-efficient. Engine oil is the lifeblood of your engine; take good care of it for worry-free driving.
