What type of engine oil should be used for the Roewe RX5?

The original engine oil brand for the Roewe RX5 is Castrol Edge. If you want to change the oil during later maintenance, you can choose brands such as Shell, Mobil, Castrol, or Total. The official manual for the Roewe RX5 recommends an engine oil model of 5W-30. Any oil model that meets these specifications can be used. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother for the car. The latter number represents the oil's kinematic viscosity at 100°C. The higher the number, the better it can maintain viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in the Roewe RX5 is as follows: Wait for the engine temperature to drop, and also allow the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain; Use a special wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new oil through the engine valve cover filler port. Generally, fill about three-quarters of a bottle; Start the engine and let it run for 5 minutes, then check for any leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.
I've been driving the Roewe RX5 for over a year now. According to the manual's recommendation, the 1.5T engine is most suitable for 5W-30 or 0W-30 full synthetic oil. The car's included manual clearly states this, and I always follow this guideline when choosing oil. For daily city driving, it runs smoothly and fuel-efficiently, without any issues like excessive engine noise or vibration. I keep the oil change interval at around 7,500 kilometers. It's best to have it done at a professional shop, though you can also check the dipstick yourself to see if the oil is clean. Oil that's too thin or too thick might accelerate carbon buildup, affecting power response. Choosing the right oil type not only saves hassle but also extends engine life, avoiding unnecessary minor repairs. After all, car maintenance is a long-term commitment—don't try to save money by using random oil brands.
As a car owner who values driving experience, I've specifically researched the engine oil options for the Roewe RX5. It primarily recommends 5W-30 full synthetic oil, but if you frequently drive on highways or mountain roads, I suggest trying 5W-40 synthetic oil. It can better handle the high-temperature load of turbocharged engines, reduce the risk of oil film rupture, and improve starting response and smoothness. The manual usually provides detailed guidance—don't overlook the API SN or SP grade requirements. Low-quality oil can easily lead to increased fuel consumption or even excessive emissions. I regularly check the oil condition; if it turns black or has sediment, it's a signal to change it. Good engine oil keeps the engine clean, so you don't have to worry about overheating even on long trips.
