Sae is society of auto engineers. The numbers are the viscosity (thickness) rating. 5 when cold. 30 when hot. The lower the number, the thicker. If you are in a warm clime, it will always be 30 weight. Since it has more than 1 no, it is multi-viscosity.

Yes you can.
the higher the SAE number, the thicker the oil and higher the viscosity of the oil.
ISO = 37 SAE Engine Oil = 15W SAE Gear Oil = 75W
20W-50 is equal to Sae 90 W.
SAE 40 has a higher viscosity.
SAE 40 has a higher viscosity.
SAE 30 motor oil if the temperature is between 30 & 75°F.Colder use SAE 10 oil.Warmer use SAE 40 oil.
Sae-20w
Only SAE 30 is equivalent to SAE-30
