What type of engine oil is recommended for the Roewe RX5?

[MacClara]

Roewe RX5 is recommended to use fully synthetic 5W-30 engine oil. Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91x10³ (kg/m³). It serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the "blood" of a car. More detailed information is as follows: 1. The engine is the heart of a car, containing numerous metal surfaces that move against each other at high speeds under harsh conditions, with operating temperatures ranging from 400°C to 600°C. In such extreme environments, only qualified lubricants can reduce wear on engine components and extend their service life. 2. Engine oils on the market can be broadly categorized into mineral oils and synthetic oils based on their base oils (vegetable oils are excluded due to their scarcity). Synthetic oils are further divided into fully synthetic and semi-synthetic types, with fully synthetic being the highest grade. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives compensate for and enhance the performance of the base oil, providing additional functionalities. Lubricant base oils are mainly classified into mineral base oils and synthetic base oils. Mineral base oils are widely used and account for a large proportion (over 95%), but certain applications require products formulated with synthetic base oils.

I've been driving the Roewe RX5 myself, and choosing the right engine oil is quite important, especially for turbocharged engines where full synthetic oil provides better protection. I recommend using full synthetic oil with a viscosity of 5W-30 or 5W-40. Brands like Shell Helix Ultra or Castrol Edge are excellent choices as they resist high temperatures, prevent carbon buildup, and keep the engine running smoothly. Always follow the manual's recommendations—generally, changing the oil every 7,000 to 10,000 kilometers is worry-free. Don't skimp by using mineral oil, as it may cause engine wear over time, leading to costly repairs. In cold weather, the 5W grade ensures smoother starts, and I've personally taken several long trips without any issues.

I've been driving the Roewe RX5 for over two years and have personal experience with engine oil. I recommend going straight for full synthetic, something like 5W-30 works perfectly. Using Castrol, I've noticed reduced engine noise and quicker power response. Never buy cheap products - they tend to accumulate deposits and damage the engine. Remember to check the filter during oil changes, and replace it every 8,000 km or so for city driving to extend engine life. I've tried different brands, but full synthetic is the basic requirement - the manual recommends oils meeting API SN standards. Spending more on proper maintenance makes for smoother, worry-free driving.

From the perspective of convenience and environmental protection, the Roewe RX5 is recommended to use long-lasting full synthetic engine oil, such as 5W-30, which can support an oil change interval of 10,000 kilometers, reducing resource waste and emissions. After using Mobil 1, I found that fuel consumption decreased slightly, and maintenance costs were reduced. Choosing oil that meets Roewe's original factory specifications is also better for the environment, avoiding frequent disposal of used oil. It is recommended to combine driving habits; for long-distance driving, 5W-40 can better protect the engine, but from an environmental perspective, long-lasting oil is more cost-effective.
