Thanks for reminding everyone of this, Curt... the light is only a suggested glow time. The glow continues for much longer after the light goes out. You can hear when the glow stops... the relay goes "clunk!". My normal cold starting procedure for a OM616 or 617 is to glow until the relay clunks off, then start cranking with my foot on the pedal... don't stop cranking until it starts. 30 seconds or longer... whatever it takes. The cranking will slowly get faster and faster. The owners manual clearly states long cranking is recommended. If you stop, you might not have enough juice to glow and crank again.
I've started OM617s well into the single digits with conventional oil... its all about the long glow, followed by the long crank. And having a good battery and starter, of course.
