OK, I'm at work, here is your official answer.
On the vicosity grade, you need to look at the chart in this booklet (S-0473-00N, Factory Approved Service Products, October 2000). For all temps (above 86 F air temp and below -13 F air temp, the following viscosities are approved:
0W30, 5W30, 0W40, 5W40, and 5W50.
For temps no lower than -4 F, but up to and above 86 F, the following viscosities are approved:
10W30, 10W40, 10W50, and 10W60.
For temps no lower than 5 F, but up to and above 86 F, the following viscosities are approved:
15W40 and 15W50.
For temps no lower than 23 F, but up to and above 86F, the following viscosities are approved:
20W40 and 20W50.
There is a note stating:
"Select oil viscosity according to the lowest air temperature expected before the next oil change".
So there you have it, as official as can be.
