Q
is thicker oil better for engine
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
The choice between thicker and thinner oil isn't about one being universally better than the other; it's about what's suitable for your engine based on design and operating conditions. Thicker oils, typically higher viscosity oils, are better at maintaining a protective film under high temperatures and loads, which may benefit older engines with larger clearances. However, they can create more resistance in moving parts, potentially reducing engine efficiency and increasing fuel consumption. Conversely, thinner oils, lower in viscosity, are recommended for many modern engines. They flow more easily at cold temperatures, ensuring quicker protection at startup, improving fuel efficiency, and reducing engine wear over time. Always refer to your vehicle’s owner manual for the manufacturer’s recommended oil viscosity. Switching to a significantly thicker oil without consulting could harm engine performance and longevity.
