What standard of engine oil should be added to the Roewe RX5?
2 Answers
The Roewe RX5 should use engine oil that meets the A1B1 or A5B5 standards. Engine oil is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. Engine oil is used for lubricating internal combustion engines, with its main functions being to reduce friction and wear on moving parts and to remove sludge and varnish from the engine. Taking the 2021 Roewe RX5 PLUS 300TGL Automatic ALI Guochao Haoronglin Edition as an example: it is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 169 PS, a maximum torque of 250 Nm, and a maximum power of 124 kW. It is paired with a 6-speed manual transmission, featuring a MacPherson strut independent front suspension and a multi-link independent rear suspension.
The Roewe RX5 is recommended to use SAE 5W-30 full synthetic engine oil, based on my two-year ownership experience. The manual clearly states the suggested viscosity is 5W-30, meeting API SP or higher standards. I frequently drive on highways, and with this oil, the engine runs smoothly with fuel consumption maintained around 8 liters per 100km. Change the oil every 8,000 kilometers, and remember to check the oil filter during replacement to ensure proper lubrication throughout the system. If unsure, refer to the label under the hood or check SAIC's official app for specific models. A reminder: avoid using 0W-20 arbitrarily, as older engines might not adapt well. In short, choose oil carefully—wrong oil can lead to reduced performance at best or accelerated wear at worst. DIY oil changes are possible, but visiting a professional shop is more hassle-free.
