Is 5w30 oil thicker than 10w30?

10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil. Thicker oil offers better lubrication of motor and engine parts.

What do motor oil numbers mean?

The first number in the oil classification refers to a cold weather viscosity. The lower this number is, the less viscous your oil will be at low temperatures. The higher number, following the “w” refers to hot weather viscosity, or how fluid your oil is at hot temperatures.

What happens if I put 5w20 instead of 5w30?

No, it is not recommended to change the oil type for your engine because 5w30 has a higher viscosity than 5w20. 5w20 oil is fairly light oil and is generally designed to work with newer engines.

What does the 30 mean in 5W-30?

What does SAE 5W-30 mean? The short answer:The numbers represent the viscosity of the oil and the W stands for WINTER. This is why you would see something like this on the label: SAE 5W-30. In a 5W-30 for example, the number before the W describes the viscosity of the oil at low temperatures.

Can I put 10w40 in a 5w30 engine?

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.

Will thicker oil damage my engine?

Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.

What is the classification of motor oil?

There are three main types of motor oil: conventional, synthetic, and synthetic blend, the last of which combines some of the properties of the first two. Within these types, there are different grades or weights that are used for specific purposes.
