What kind of oil does Lexus use?
2 Answers
Lexus can use two types of engine oil, one is the original SM-10W30 oil, and the other is the conventional pure brand oil, model SM-5W40. Introduction to engine oil: Engine oil, also known as engine lubricant, can lubricate and reduce wear on the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber. It is known as the 'blood' of the car. Functions of engine oil: Engine oil can form a seal between the piston rings and the piston, reducing gas leakage and preventing external pollutants from entering. When the pressure at the engine cylinder port rises sharply, suddenly increasing the load on the piston, piston chips, connecting rod, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load. Good engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, and wash away dirt generated on the working surfaces of parts through the flow of the lubricating oil.
Lexus recommends using full synthetic motor oil, with viscosity grades like 0W-20 or 5W-30 being the most suitable for most models. I've been driving a Lexus LS for several years and always insist on using full synthetic oil because it keeps the engine running smoothly, reduces wear, and also lowers fuel consumption. The oil change interval is generally every 7,000 to 10,000 kilometers, and the manufacturer's manual emphasizes selecting oil products that meet the ILSAC standard. Beginners often forget to check the oil level; regularly using the dipstick to see if oil is low is crucial. During maintenance, I also pay attention to the ambient temperature, making slight viscosity adjustments between winter and summer for better performance. These details make driving safer, extend the vehicle's lifespan, and eliminate noise issues during daily driving.
