What does Mercedes-Benz 229.5 certification mean?
1 Answers
Mercedes-Benz 229.5 certification refers to engine oil models that meet the requirements of this vehicle's engine. Below are the detailed explanations: 1. Main features: The engine is the heart of a car, containing many metal surfaces that rub against each other during movement. These components operate at high speeds, in harsh environments, and can reach working temperatures of 400°C to 600°C. Advanced technology can convert natural gas into crystal-clean fully synthetic base oil, which is then enhanced with unique power cleaning technology to create lubricants with superior cleaning and protective performance. Under such extreme conditions, only qualified lubricating oil can reduce engine component wear and extend service life. Engine oils on the market can be broadly divided into two categories based on their base oil: mineral oil and synthetic oil (vegetable oil is not considered due to its scarcity). Synthetic oils are further divided into: fully synthetic and semi-synthetic. Lubricant base oils are mainly classified into mineral base oils and synthetic base oils. Mineral base oils are widely used and account for a large proportion (approximately over 95%), but some applications require products blended with synthetic base oils. 2. Performance: Lubricity, viscosity-temperature characteristics, low-temperature operability, etc.
