caribou1: Your advice is very much appreciated, thank you. With the CRD I have never used the part-time yet, we leave it in full-time on our dirt/rock/gravel/ roads. On pavement we take it out of full-time, unless it's needed.
   Last night it got down to -25C. Notice I used the C temp for you, I thought you might like that. We have 2" of ice covered with 1" of packed snow. My wife and I have been iced in here from last Thurs. night, and until the ice gets soggy we are not moving. Ice is not something I intend to deal with on the very steep hill we live on the top of. The ice- cycles on the eves of the house are mostly 18" long.
   The Green Beast is frozen solid and doors and hood don't even come close to wanting to budge open. I am glad we are retired because there is no way anyone beyond our our home down the road are going any place. Gas generators are at a huge demand. The home improvement chain stores are issuing numbers to people and as the generators come in by the truck load. Most generators sell for $1,295.00 Finding gasoline has been a problem in Springfield MO, and several other places. Because the electricity being out, along with some houses that just can't keep enough heat has had the Red Cross, and Salvation Army have opened many places so people can be fed and sleep and kept warm. I have never seen so many people who really needed to be in these centers. I think on the Lake of the Ozarks there are about 10 to 15 such places. We have a Waterford Wood Stove ( made in Ireland) that we use for heat. This we can also cook on if we needed to. We designed our home to be so if we got stranded we could be fine for several weeks if we had to. It really feels good to be independent and self reliant. Has this winter been bad for you?

Maybe you'd like to move to Portland?

Farout... Must be something to see the snow untouched, here in florida has been very hot A/C run all day today, is very hot for the winter. Is your CRD doing as it should after the F37, do you think that gas mileage is doing ok, my seems to me that is not doing so good, maybe is my imagination but maybe not.

I had mine in for the F37 and replacement of the EGR flow control valve. It has 61000 miles on it.
The tech pulled out a lot of "gunk". They blamed it on the Rotella 5W40 and PowerService.
I am blaming it on the CCV system design.
I wonder if it will plug up the intake manifold to the point where it won't run right, I remember an earlier post about VW having that problem.
Any thoughts?

Farout, you guys stole our winter. We have close to +15C and blue sky.
I can report about using winterized fuel during warm weather
Believe it or not, I get summer mileage now. So the temperature seems to play a very important role in the injection parameters.

The technician at the local dealer mentioned the "gunk" that gets into the system. I find it strange that a fuel additive that gets consumed in the combustion process would contribute to anything save for more blowby which diesel engines by their nature have more of than gassers. I used the Power Service products for several tankfuls and could find no discernible difference over the RedLine product I use consistently. The oil could be a contributor if it has a high vaporization rate and according to the tech, those using the recommended Mobil 1 0W-40 have lots of "gunk" in the intake system.
 
Frankly, I do not know what to say at this point. I have switched over to Amsoil 5W-40 "CJ" rated oil and will watch the aftercooler hoses to see how much "gunk" they accumulate. If I start seeing an increase in "gunk" in the aftercooler hoses then I will switch back to the 15W-40 synthetic from Amsoil. While using that oil, the aforementioned hoses remained nearly dry with only a tiny bit of "gunk" that settled in the lowest portion of the hoses.

That is nothing usual. They drive like that on dry pavement in the metro Washington D.C. area.

lol, I do get on I-66 and 81 almost every year visiting my sister but I'm usually able to avoid the Beltway. Glad I'm not commuting in that mess.

This video is frightening. I don't understand how a car can turn around and accelerate at the same time
Or are we seeing the effects of the ABS system when a person's last reflex is to slam the brakes and wait?

I could be mistaken, but at least one of those bumper cars looked to be a 4WD SUV too.
