What type of engine oil is suitable for the Besturn X80?
2 Answers
Fully synthetic SM5W40 engine oil, brands such as Mobil and Shell can be used. Functions of synthetic engine oil: Lubrication and wear reduction: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing bush. It prevents excessive wear of parts and aids in cooling. The engine oil carries heat back to the oil tank and then dissipates it into the air, assisting the radiator in cooling the engine. Brief description of engine oil classification: Internationally, engine oil is evaluated according to the API (American Petroleum Institute) standard, which is divided into the S series (gasoline engine oil) and the C series (diesel engine oil). The "S" prefix series represents oil for gasoline engines.
I've been driving the Besturn X80 for several years and find both 5W-30 and 5W-40 engine oils quite suitable, mainly depending on the season and weather. In hot summers, using 5W-40 with higher viscosity provides better engine protection, while in cold winters, 5W-30 offers better fluidity for quicker starts. The manual recommends synthetic oil with API SN specification. I've used Castrol Edge and Mobil 1, both felt smooth with reduced noise. Engine oil is no trivial matter - choosing the wrong type can affect fuel consumption and acceleration. Before long-distance drives, I always check the oil level to prevent mishaps. Remember to change the oil every 8,000 km or six months, and replace the oil filter simultaneously, otherwise accumulated impurities may damage the engine, which would be more costly than beneficial.
