Which engine oil is best for Changan CS75?

[VonMorgan]

Changan CS75 is recommended to use 5W30 engine oil, which is selected based on temperature conditions and meets the quality grade of SL or above as specified in GB11121. The number before 'W' indicates the low-temperature viscosity - the lower this number, the faster the engine oil can be pumped and circulated in the engine during cold starts. The number after 'W' represents high-temperature performance - a higher value means thicker oil during operation, providing better high-temperature protection, cushioning capability, and noise reduction. The Changan CS75 is a compact 5-door, 5-seat SUV with dimensions of 4650mm (length) x 1850mm (width) x 1715mm (height), a wheelbase of 2700mm, and comes equipped with a 6-speed manual transmission.

I've been driving my CS75 for three to four years and particularly love its power. For engine oil, I use full synthetic oil like 5W-30 because it starts quickly in cold weather, saves fuel, and provides smoother acceleration on highways. I usually choose Mobil 1 or Shell, which meet the manufacturer's recommended SP grade, to avoid carbon buildup issues from low-quality oil. The oil change interval is 10,000 kilometers, even in winter. During routine maintenance, I check the oil level to ensure there's no oil burning, which helps extend the engine's lifespan. On long drives, the power remains steady without any shaking, giving me peace of mind. Always check the owner's manual requirements first and avoid switching to oils with significantly different viscosities. Although the overall cost is higher, it's worth it because protecting the car is most important.

I drive my CS75 to commute, which is fuel-efficient and durable. For engine oil, I prefer cost-effective semi-synthetic options like Shell Helix 5W-30—affordable and long-lasting. I change it every 8,000 km, and it maintains quality even in summer heat. It's sufficient for city commuting; no need to splurge on premium full-synthetic oils. An API SN or higher rating is fine—too thin viscosity may cause oil burning, so follow the manual. I once used cheap oil and noticed louder engine noise; now I stick to branded oils for smoother, quieter drives. Adding a cleaning additive during highway or long trips helps lower fuel consumption too.

As a CS75 owner, I use it for daily family commuting. It's recommended to use 0W-30 synthetic oil for quick cold starts, ensuring no worries when driving kids to school. Choose common brands like Great Wall fully synthetic oil for convenience and compliance with standards. Change the oil every six months or 7,500 kilometers—don't delay too long. Simply check the oil level to keep it within the normal range. The car drives smoothly without noise, handling suburban roads with ease. Always refer to the manual for the right viscosity to avoid issues.
