Which oil is better 5W-30 or 10w40?

Which oil is better 5W-30 or 10w40?

The first number in the motor oil’s name describes the oil’s cold viscosity. A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.

Can 10w40 be used instead of 5W-30?

Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.

Can I use 5W-30 in Mercedes?

What is 10w40 oil used for?

10w40 is better suited for hot weather or heavy loads. When you expect your vehicle’s operating temperature to be higher than most casual driving cars, using 10w40 is recommended. The higher viscosity of 10w40 at high temperatures reduces wear and tear when putting more pressure on your vehicle’s engine.

What is the difference between 10W and 5W oil?

A 10W or 5W is the index for how easily the oil flows in winter (hence the W). A 10W oil thickens more than a 5W. The other number indicates the oil’s resistance to thinning at high temperatures.
