Question

A higher grade number for oil means it is _____.
A. heavier
B. more viscous
C. less viscous
D. more important

Answer 1

Answer:

For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil. The higher number, following the “w” refers to hot weather viscosity, or how fluid your oil is at hot temperatures. The higher the number, the thicker the oil at a specified temperature. so it's B

Explanation:

Answer 2

When there is a higher grade number for oil then it means that it is:

• B. More viscous

According to the given question, we are asked to show what it means when there  is a higher grade number for oil.

As a result of this, we can see that viscosity has to do with the resistance of a fluid when it comes in contact or experiences a change in shape and when there is a higher grade number for a fluid like oil, then it would be more viscous

Therefore, the correct answer is option B
