Is it better to use 5w30 or 5w40 for the Edge?

[StLucille]

The Edge performs better with 5w30. The difference between 5W30 and 0W40 engine oils lies in their high and low-temperature performance. 0W40 has better low-temperature fluidity, making it suitable for colder environments, while its higher high-temperature viscosity provides better high-temperature protection but also increases fuel consumption. Here is some information about engine oil: 1. Engine oil: Engine oil, also known as engine lubricant (English name: Engine oil), with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. 2. Main characteristics: The engine is the heart of a car, containing many metal surfaces that move against each other. These components operate at high speeds, in harsh environments, and can reach temperatures of 400°C to 600°C. Advanced technology can convert natural gas into crystal-clean fully synthetic base oil, to which unique power cleaning technology is added, creating lubricants with superior cleaning and protective performance.
