Why Can't Eagle Flag Engine Oil Be Purchased Online?
1 Answers
Different industries have different marketing channels, so some engine oils cannot be purchased online. Here is a partial introduction to engine oil: 1. Composition: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives are an important part of the lubricating oil. 2. Types of engine oil: The winter oil grades classified by SAE lubricant viscosity are 0W, 5W, 10W, 15W, etc. The symbol W stands for winter, and the smaller the number before W, the lower the low-temperature viscosity and the lower the applicable minimum temperature. The summer oil grades classified by SAE lubricant viscosity are 20, 30, 40, 50. The larger the number, the higher the viscosity and the higher the applicable maximum temperature.
