You can use Mobil 1 or Castrol Edge fully synthetic engine oil. Introduction to engine oil: Engine oil, also known as engine lubricant, serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricants, determining their fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, imparting new characteristics, making them an essential part of lubricants. Characteristics of engine oil: The engine is the heart of a car, containing numerous metal surfaces that move against each other at high speeds under harsh conditions, with operating temperatures ranging from 400 to 600 degrees Celsius. Advanced technology can convert natural gas into crystal-clean fully synthetic base oil, which is then combined with unique power cleaning technology to create lubricants with superior cleaning and protective performance. Only qualified lubricants can reduce engine component wear and extend service life under such severe operating conditions.
