How Many Liters is 3.5kg of Engine Oil?
2 Answers
3.5kg of engine oil is approximately equal to 4 liters. Characteristics of engine oil: Engine oil is the lubricant used in engines, composed of base oil and additives. It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve any deficiencies in the base oil's performance, imparting certain new characteristics. Meaning of engine oil symbols: The 'W' stands for winter. The smaller the number before the W, the lower its low-temperature viscosity, the better its low-temperature fluidity, and the lower the applicable temperature. The larger the number after the W, the higher its viscosity, and the higher the applicable temperature.
I'm sharing from my experience at an auto repair shop, oil density is a common topic. The density of engine oil is generally around 0.85kg/L, so 3.5kg is approximately 4.12 liters. But don’t underestimate this number—temperature has a big impact. In winter, when it's cold, the density increases and the volume shrinks to about 4.0 liters, while in summer, when it's warm, the density decreases and the volume expands to around 4.2 liters. Though the difference seems small, precision matters during oil changes. Different types of oil also have varying densities. For example, mineral oil has a lower density of 0.83kg/L, resulting in 4.22 liters, while synthetic oil has a higher density of 0.87kg/L, resulting in 4.02 liters. My advice is to always check the packaging label or use a measuring container when buying oil—don’t guess and risk overfilling or underfilling, which can damage the engine. These calculations are quite useful during regular maintenance, as paying attention to details can extend your car’s lifespan.
