What oil is better for old cars?

Is 5w30 better for older cars?

5w 20 and 5w 30 engine oils are commonly used in colder temperatures. However, they are recommended for older engines and light-duty use. This is because an oil with a higher rating indicates that it is thicker and suits well those engines which run hot easily.

Is 5W-30 oil good for car engine?

5W-30 oil is unsuitable for extremely high temperature use since, at these temperatures, car engines require a thicker oil with proper bearing support and cushioning. As 5W-30 oil is comparatively thinner than any other multigrade oil like 5W-40, it may not lubricate the engine well. 2. Is 5W-30 Oil Suited For Heavy-Duty Use?

What is the difference between 5W and 30?

The 5W in the oil grade 5W-30 states that the oil must meet a certain maximum flow at lower temperature. Therefore, the lower the W rating will result in better performance during cold temperatures. The 30 rating within the oil grade refers to the viscosity rating that the oil must reach at 100 degrees.

What is the difference between 0w40 and 5w40?

The longer it takes for the oil to pass through, the higher the SAE code is assigned due to the higher viscosity, which means the 5w40 has a higher viscosity than 5w30. Read more about the difference between 0w40 vs 5w40. More… Why Is Thickness Important? Why Is Thickness Important?
