Is it better to use 5w30 or 5w40 for the Edge?
2 Answers
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.
I've always lived in the north where winters are extremely cold, and the oil must flow quickly when starting the car. I've been driving the Ford Edge for over three years, and 5W-30 is noticeably thinner than 5W-40 in low temperatures. On mornings when it's minus twenty degrees, the engine starts without any difficulty, and lubrication is much smoother after startup. The difference in summer is minimal, but in winter, 5W-40 is slightly thicker, especially for older engines, which can feel strained. Fuel efficiency is also good, with 5W-30 offering slightly better mileage. Remember to change the oil according to the season, and don't skimp by switching back and forth to save money. Always check the oil dipstick and make sure not to use counterfeit or low-quality oil, as it can damage the engine.
