Does 98 Octane Gasoline Contain Ethanol?

[VanNaomi]

SINOPEC's 98 octane gasoline does not contain ethanol; it is pure gasoline. Below is an introduction to engine oil knowledge: 1. Introduction: Engine oil, also known as engine lubricant, with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is hailed as the 'blood' of automobiles. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve the shortcomings of the base oil's performance, endowing it with certain new properties, making it an essential part of lubricating oil. 2. Requirements: As a type of machinery, engines have common requirements for lubricating oil similar to general machinery, such as appropriate viscosity, certain anti-oxidation, anti-wear, anti-corrosion, and viscosity-temperature performance requirements. However, engines are also a special type of machinery, and their requirements for lubricating oil have unique aspects.
