Do New Cars Need an Oil Change in Winter?
1 Answers
New cars do not require a special oil change for winter. There is no need to specifically switch to winter-grade oil for new cars, as manufacturers have already pre-filled the engine with oil suitable for the sales region during production, ensuring it can handle local conditions. Engine Oil: Also known as motor lubricant. With a density of approximately 0.91×10 (kg/m³), it serves multiple functions for the engine: lubrication and friction reduction, auxiliary cooling, sealing against leaks, rust and corrosion prevention, and shock absorption. Often referred to as the "blood" of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent, determining the fundamental properties of the lubricant, while additives compensate for and enhance any shortcomings in the base oil's performance, providing additional capabilities. Additives are a crucial part of the lubricant. Effects of Low Temperatures on Engine Oil: In cold conditions, engine oil thickens and may not flow smoothly, sometimes even stopping completely. This delays its circulation to critical engine components, affecting lubrication and protection. Starting the vehicle and driving immediately can lead to dry friction, which over time may damage cylinder walls, cause abnormal engine noises, severe idle vibrations, and even oil burning issues.
