What is the engine oil specification for the Changan CS55PLUS Blue Whale Edition?

[StElijah]

The Blue Whale 1.4T engine uses 0W-20 engine oil. Summer oil specifications: 20, 30, 40, 50 - the higher the number, the greater the viscosity and the higher the applicable maximum temperature; Winter oil specifications: 0W, 5W, 10W, 15W, 20W, 25W - the letter W stands for Winter, and the smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature; All-season oil specifications: 5W-20, 5W-30, 5W-40, 5W-50, 10W-20, 10W-30, 10W-40, 10W-50, 15W-20, 15W-30, 15W-40, 15W-50, 20W-20, 20W-30, 20W-40, 20W-50 - the smaller the winter number, the higher the viscosity represented by the summer number, and the wider the applicable temperature range.

I remember when maintaining the Changan CS55PLUS Blue Whale edition, the official recommendation is to use 5W-30 full synthetic oil, preferably the SAE standard type, because the engine is turbocharged. 5W-30 provides good fluidity and protection, especially performing stably at high speeds in high-temperature environments. It's advisable to choose SN or SP grade oil, with reliable brands like Castrol Edge or Mobil 1. I've used them myself, and the engine runs quieter with slightly improved fuel efficiency. Don’t forget to change the oil regularly—generally every 5,000 kilometers or six months, depending on the vehicle’s reminder. Delaying it excessively may lead to engine wear or increased carbon buildup. Before driving, always check the dipstick to ensure the oil level is normal. This habit can prevent minor issues from turning into major faults. Get into the routine of checking the owner’s manual, and avoid experimenting with oil that has excessively high viscosity, as it could affect power output.

I've been driving the Changan CS55PLUS Blue Whale Edition for a while now. Based on practical experience, 5W-30 synthetic oil is the most suitable choice. The engine manual recommends this grade - its viscosity isn't too high, providing smooth protection for turbo components while preventing excessive friction during cold starts. After several oil changes myself, I've noticed smoother acceleration without significant fuel consumption increase. Never opt for cheap mineral oil during changes - though synthetic oil costs more, its durability is superior. Typically requires replacement every 8,000 km or annually, adjusted according to urban driving habits. During routine maintenance, technicians always emphasize oil quality importance. I recommend authorized service centers to avoid counterfeit products that could damage engine internals - never compromise quality to save money.

As someone who frequently handles vehicle maintenance, I recommend using SAE-standard 5W-30 synthetic oil for the Changan CS55PLUS Blue Whale Edition. The reason lies in the engine type - the lower viscosity of 5W-30 provides better fluidity during cold starts, offering superior protection for the turbocharger. SN-grade certified oil effectively reduces deposits and enhances performance. Remember to replace the oil filter every 5,000 kilometers, with the overall maintenance cycle kept within six months. Proper oil maintenance will significantly extend your vehicle's lifespan.
