Should I Use Grease or Engine Oil for the Chain?

[JaydenLynn]

Check if there is an oil box. If there is an oil box, use engine oil, as the chain passes through the oil box for lubrication. If there is no oil box, grease is better. Next, consider the size and length of the chain. For larger chains, such as those above RS100, or chains longer than 1 meter, use engine oil. For smaller chains, use grease. Relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It 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 often referred to as the "blood" of a car. 2. Composition: Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, imparting new characteristics. Additives are an important part of lubricating oil.
