Multi-weight oils (such as 10W-30) are a new invention made possible by adding polymers to oil. The polymers allow the oil to have different weights at different temperatures. The first number indicates the viscosity of the oil at a cold temperature, while the second number indicates the viscosity at operating temperature.

There is no country code +530, and there are no valid numbers beginning with +53 0. (Country code +53 is Cuba, but no Cuban numbers begin with 0.)
530 is an even number. Odd numbers end in 1, 3, 5, 7, or 9; even numbers end in 2, 4, 6, 8, or 0.
It depends. Some numbers in area code 530 are local to you, but others are toll.
When there are differences in numbers in motor oil, there is a difference in viscosity. A lower number has lower viscosity and is good for warmer climates. A higher number is good for colder climates.
