Cold Start Survey

This is just my curiosity.

For those with the OBS PSD, 94.5 to 97. How cold can you start without plugging in? I would like for this to apply to PSD's with a stock starter (no denso, or SD starter), fully operational glow system, and good batteries. If you have an NBS please specify so. (also Specify *C or *F)

for me its a very rough start at 15*F or 20*F with 4 bad glows and weak starter.

My truck will start at 32* with NO glow plugs (relay unplugged), runs rough for a second, smooths out, minimal white smoke
will not start at 24* with no plugs (relay unplugged), cranks over, pours white smoke, will not start

Coldest I've ever started her is 14* with everything operational, good batts, GP system good, etc...runs rough for a second, then purrs like a kitten

I'm in Vermont ski bumming the winter and the place I rent doesn't have a place for me to plug in. I've got 8 brand new gps and 2 new 850cca batteries. I wait about 30 seconds after the WTS light goes off then fire away!

What weight oil are you using? If you can always plug in before starts then1 15w40 is fine but I was having problem with the oil not being able to fire injectors even though it cranked fast. I'd switch to 5w40 synthetic in the winter

I started mine earlier today at 23F without having it plugged in and 15w40. All GPs work with good batteries and starter(stock). I just turned the key to on and when the WTS light turned off I turned the key off and did it again. I did this 4 times before actually cranking it and it started great with just a little puff of smoke.

Forgot to plug mine in last night and had to go pick up the kids. -12 celcus, warmed with glow plugs started and stalled, warmed again and tit fired up. Ran a bit rough for 20 seconds, then smoothed out.
