12 degrees in Atlanta this AM. '81 300SD cranked up first time; just like in warm weather. As I backed it out of the garage, it would not spin up any revs but then heading down the driveway and onto the street it perked up just fine. Drove it about two miles and parked it back in the garage. Pretty good for 255,000 miles. The only thing I have done to improve cranking is have the valves adjusted and using 5w30 oil.

Is your garage enclosed?

low compression
230psi
290
380
240
225k on it, valves adjust correctly 20x50 oil.
20w50 is most likely NOT diesel rated and should NOT be used. I just had to brow beat a friend of mine for this. Just because the PO used it doesn't mean you should. 15w40 atleast. 5w40 if you want to start in cold. You only have one piston within spec, time for a leakdown :(

5w30 IS NOT diesel rated.


Where do you guys get these oil suggestions from?!

I haven't tried starting Max the last few days. Perhaps I'll plug in his block heater before I do. I hope it works. I've never used it before.

I also fired up my 83 240D which has been sitting in the garage in sub 0 temps / no block heater. Started great! Actually seemed to crank and fire up quicker and easier than our Jeep which is nearly 2 decades newer. I have been using the Rotella syn 5w40, which I think helps.

I have found that a garage makes quite a difference in temperature. Even if you are not heating it there is quite a bit of solar heating that goes on.

Amsoil makes a 5/30 diesel rated oil, it's their Series 3000. It is supposed to be their premium diesel oil. I use it in my Dodge PU with excellent results.

How do you know?

Can you compare the wear on your Dodge with the wear on a similar engine that uses 5W-40?

why would you use a thinner hot oil that is specified in your manual? xW40 is what's recommended... why use thinner? that hot spec is important in a diesel... each MASSIVE pulse of the explosion/burn is destructive enough, thinner oil can damage things... get an oil analysis, I bet you have wear you shouldn't.
