Ford Explorer: 92 or 95 Octane?
1 Answers
Ford Explorer uses 92 octane. The octane number represents the gasoline's anti-knock performance index, and higher isn't necessarily better. Car owners should choose gasoline with different octane ratings based on the engine compression ratio specified in the vehicle's user manual. Engine Oil Function: Engine oil lubricates and reduces friction, assists in cooling, seals against leaks, prevents rust and corrosion, and cushions shocks. It's known as the 'blood' of a car. Choosing the right engine oil and changing it regularly can maintain the engine in good condition and extend its service life. Engine Oil Selection: When selecting engine oil, the most expensive option isn't always the best. Instead, the right choice depends on the car engine's characteristics and the driver's habits. Engine oil can be categorized based on winter and summer use. For winter, the primary consideration is the low-temperature viscosity grade, while in summer, due to higher temperatures, there's no need to choose oil with a superior low-temperature viscosity grade.
