What does GF-6 mean for engine oil?

[LeAaliyah]

GF-X grades are the engine oil quality certification standards established by the International Lubricant Standardization and Approval Committee. These standards place greater emphasis on fuel economy, hence generally using lower viscosity. The number following GF is generally considered to correspond to the national emission standards, with GF-6 commonly referred to as China VI. Below are some relevant details about engine oil: Introduction 1: The engine is an indispensable part of a car, and engine oil is an indispensable part of the engine, highlighting its importance to the vehicle. Regarding engine oil requirements, each vehicle model has its own compatible engine oil specifications, which can be found in the car's user manual. Introduction 2: If the engine oil has been used for an extended period, it is crucial to replace it promptly. Prolonged use can reduce the oil's viscosity and correspondingly diminish its lubricating effectiveness, failing to provide adequate lubrication and protection for the engine. Therefore, timely replacement is essential. Introduction 3: Additionally, the required viscosity of engine oil varies under different temperature conditions. When changing the oil, drivers should take into account the temperature of their driving environment.
