The dedicated engine oil for the Changan CS35 is the original factory oil, with a grade of 5w30. This type of oil offers excellent lubrication and strong low-temperature fluidity, making it one of the commonly used engine oils in the automotive market. Engine oil, or engine lubricant, serves multiple functions including lubrication and wear reduction, aiding in cooling, sealing against leaks, preventing rust and corrosion, and providing shock absorption. The Changan CS35 is an SUV independently developed by Changan Automobile, with body dimensions of 4160mm in length, 1810mm in width, and 1670mm in height, and a wheelbase of 2560mm. The overall exterior design of the Changan CS35 is robust and dynamic, featuring smooth, sharp, and clean lines. The front fascia is highly impactful, with a grille that combines grandeur and refinement. The headlights adopt a chiseled design style, complemented by naturally flowing curved trim rings and barrel-style lens covers.

I have been driving the Changan CS35 for over three years. The original specialized engine oil is usually Shell's Helix series, with SAE 5W-30 specification. The 4S service centers use this oil, which is specifically designed for Changan engines and offers excellent cleaning performance. During the summer heat, I pay extra attention to maintaining the proper oil viscosity to avoid engine overheating and stuttering. I have also used Castrol oils of the same grade when changing the oil myself, and the results have been equally good. I recommend that car owners frequently check the user manual for official recommendations, which specify the brand and replacement interval—typically around every 5,000 kilometers. Engine oil is the heart of the car; choosing the right brand ensures smoother performance and reduces carbon buildup issues. Additionally, it’s crucial to select oils with API certification to guarantee proper lubrication and protection. Avoid using cheap, off-brand oils to prevent potential engine problems.

Regarding the dedicated engine oil brand for the Changan CS35, the manufacturer recommends Shell, but the key lies in the oil specifications. The engine requires SAE 5W-30 viscosity and must meet API standards such as SN or SP grade, ensuring stable fluidity in both high and low temperatures to protect the piston system. Differences between brands mainly lie in the additive formulations, with the manufacturer's oil tested for better compatibility to prevent seal wear and noise. However, if the original brand is unavailable, equivalent specification oils from Castrol or Mobil are also acceptable, provided they are purchased from legitimate channels with proper certification. Oil that is too thick can increase fuel consumption, while oil that is too thin can accelerate wear. Regular maintenance should include checking the dipstick for color changes to ensure timely replacement.

If you're a new CS35 owner wondering about the dedicated engine oil brand, the simplest way is to check the user manual or call the 4S store. The manufacturer typically uses Shell oil, such as the Helix series with SAE 5W-30. I learned this during my first maintenance service - the technician told me Shell provides stable performance for Changan engines. When purchasing oil yourself, choose reputable brands with the same specifications and ensure API certification to avoid counterfeits. Never opt for cheap, low-quality oil as it can damage engine longevity. Regular maintenance is crucial - change oil approximately every 5,000 kilometers to maintain optimal vehicle performance.

The original engine oil for Changan CS35 is mainly Shell, but you don't have to stick to the brand when choosing. The key is the SAE 5W-30 specification. There are products of this grade from Castrol and Mobil in the market, which are reliable in performance and more cost-effective. I often recommend car owners to purchase products with API certification from regular stores to avoid counterfeit issues online. Engine oil is crucial for engine health, and using inferior oil may cause carbon deposits or noise. The repair cost is much higher than the oil itself. Change the oil regularly according to the manual, every six months or 7,000 kilometers. Choosing the right oil can extend the car's lifespan, so don't overlook this small investment.
