Q
thicker engine oil grade
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Thicker engine oil grades, such as 10W-40 or 20W-50, are designed for higher temperature conditions and older engines with higher mileage. These oils have a higher viscosity, meaning they're less fluid at normal operating temperatures compared to thinner oils like 5W-30. This property allows them to create a stronger film between moving parts, reducing wear and maintaining engine performance in demanding conditions or in engines with looser tolerances due to wear. However, using a thicker oil than recommended by the manufacturer can lead to reduced fuel efficiency and difficulty in starting the engine in colder climates. Always consult your vehicle's owner manual or a professional mechanic to choose the best oil grade for your specific engine needs and environmental conditions.
