A 616 or 617 starting at 9F with 15w40 in it would take a REALLY good battery, REALLY healthy starter, and REALLY good compression/glowplugs on that engine. Otherwise, likely not happenin.

1. 5w40 synthetic oil
2. New glow plugs
3. Valves adjusted
4. Healthy starter (makes a huge difference)
5. Healthy Battery
6. Glow for full 30+ seconds before cranking

With all that in order it should fire up pretty quickly at 9F if the engine is still healthy.
