Should I Use Grease or Engine Oil for the Chain?

[AllieRose]

Check if there is an oil box. If there is, use engine oil, as the chain passes through the oil box for lubrication. If not, grease is a better option. Next, consider the size and length of the chain. For larger chains, such as those above RS100 or longer than 1 meter, use engine oil. For smaller chains, grease is preferable. 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. 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, determining the fundamental properties of the lubricant, while additives compensate for and enhance the performance of the base oil, providing additional functionalities. Additives are an essential part of lubricants.
