What is the recommended engine oil specification for the Geely Boyue Pro?
3 Answers
The official manual for the Geely Boyue Pro recommends using 5W-40 engine oil, with Shell semi-synthetic oil being the brand used by the manufacturer. For subsequent maintenance and oil changes, you may choose from brands such as Mobil, Shell, Castrol, or Total. The viscosity of engine oil changes with temperature, so it's crucial to pay attention to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity, with 5W representing the ability to withstand temperatures as low as -30°C. A smaller number here means better low-temperature fluidity, ensuring smoother cold starts for the vehicle. The second number represents the oil's kinematic viscosity at 100°C, with higher values indicating better ability to 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 a Geely Boyue Pro is as follows: Wait for the engine temperature to cool down, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine and let it run for about 30 seconds to allow the oil in the main oil passage to drain out; Use a specialized wrench to remove the oil filter; Apply some oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the oil filler cap on the engine's valve cover, typically filling about three-quarters of the oil container; Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If leaks are found, repairs should be made; After stopping the engine, pull out the oil dipstick to check that the engine oil level is within the standard range.
I've been driving the Geely Boyue Pro for several years, always using 5W-30 fully synthetic oil as clearly stated in the manual. This oil is crucial, especially during cold starts, as it protects the engine from wear. I usually choose brands like Shell or Mobil, changing it every 5,000 to 7,000 kilometers, which saves fuel and extends engine life. During long summer trips, the right oil reduces overheating issues and maintains stable fuel consumption. Remember not to buy the cheapest options, as poor-quality oil can lead to carbon buildup and affect performance. In extremely cold regions, other oil grades might be recommended, so I suggest checking your manual to avoid surprises. This makes daily maintenance simple and worry-free.
From the perspective of oil specifications, the 5W-30 full synthetic oil is most suitable for the Boyue Pro. This code indicates good low-temperature fluidity (effective at -25°C) and stable high-temperature viscosity, making it adaptable to various climates. Synthetic oil offers better resistance to high-temperature oxidation than conventional oil, providing stronger protection for turbocharged engines like the 1.8T model. Brands such as Castrol offer good cost-performance, with an ideal replacement interval of every 7,500 kilometers. Using the wrong oil long-term can increase friction losses and shorten engine life by over 100,000 kilometers. Pay special attention in areas with significant temperature variations, and it’s best to refer to the specific recommendations in the manual. Remember to replace the oil filter during oil changes—these maintenance details are simple to handle overall.
