The difference between 20 degrees and -30 degrees is 50 degrees. This is because you subtract the smaller value (-30) from the larger value (20) to find the difference. Mathematically, 20 - (-30) = 50.
5w20 is a little thinner at operating temps than 5w30

The difference between 20 degrees Celsius and 50 degrees Celsius is 30 degrees.
The temperature difference between -30 degrees and 20 degrees is 50 degrees. Negative 30 degrees is 50 degrees lower than 20 degrees.
The main difference is that 5w20 is thinner at operating temperatures than 5w30. They both have similar cold flow ability.

Viscosity. 5W-30 is a "thinner" oil than 10W-40 is.
29 - 23 = 6
It is: 29-23 = 6
