oil would be fine; found the following on a Castrol and Mobil 1 website:

Grades
In order for motor oil to perform its major function - lubrication - its viscosity (the measure of it's thickness or resistance to flow) must be capable of holding up under your engine's extreme temperature conditions.
Oil thins when heated and thickens when cooled. Choosing the proper viscosity grade for the ambient temperature of your geographic location becomes vitally important.
A monograde is an oil whose viscosity is defined at only one temperature, either high or low.
A multigrade must meet both high and low temperature viscosity requirements simultaneously.
This makes multigrades an easy and popular year-round choice for drivers who experience hot summers and harsh winters. They are easily recognized by the dual viscosity designation (i.e. 10W-30 where the 10W is the low temperature, or winter designation and the 30 is the high temperature designation). It is the viscosity modifier additive that produces a thickening effect at high temperatures but is dormant at low temperatures.
Which viscosity grade is right for you
SAE Viscosity Grade
Temperature Conditions
Descriptions
5W-30
Below 0° F
Provides excellent fuel economy and low temperature performance in most late-model automobiles. Especially recommended for new cars.
10W-30
Above 0° F
Most frequently recommended viscosity grade for most automobile engines, including high-performance multivalve engines and turbo-charged engines.
10W-40
Above 0° F
The first multigrade introduced. A good choice for controlling engine wear and preventing oil breakdown from oxidation. Note: Always check your owner's manual or warranty requirements before using this grade.
20W-50
Above 20° F
Provides maximum protection for high-performance, high-RPM racing engines. Excellent choice for high temperature and heavy loads such as driving in the desert or towing a trailer at high speeds for long periods of time.
SAE 30
SAE 40
Above 40° F
Above 60° F
For cars and light trucks, where recommended by manufacturers. Not recommended when cold-temperature starting is required.
Mobil 1: I've switched to 0W-40 Mobil 1 for my 9kT's (87 9kT, 97 CSE, 97 Aero) for fall and winter. Key point regarding your question: it's pour point is -54C. Here's their site:
