Well, had duty on sunday, and when I went out to start my 69 220 D (left on the street sadly), it was about 10 - 12* with it being max 0* with wind chill. Figured this would be the true test of the beast..............
Glow plugs...........I have never replaced them, and I have had the car for 4 years. The car sat for 2.5 years before I got it, and sat another 1.5 years prior to November (due to being out to sea). Had the injectors rebuilt last spring, and battery is about 1 1/2 years old, and no block heater.
Had to do 4 cycles, but when it started, sounded like it normally does every other morning.
Was pretty happy, although can't take the chance of being stuck at work 35 miles from home, so will drive the Tahoe if it is going to be less than 20 on my duty day.
