The owner's manual describes "regular" and "premium" oil both of which are presumably suitable to use.

"regular" for "moderate" service and "premium" for "more severe" service.

They also recommend SAE 20 or 20W oil for all except the most extreme temperatures.

30 is recommended only when daytime temperatures are above 90 or the car is used for extreme high speeds.

10W for extreme cold.

So 10W30 premium oil would cover practically all occasions.

I don't know why the don't mention multigrade oils.
