Synthetic Oil
After the cold temps that we have had here in Fairbanks recently, I am considering changing over to synthetic oil because I have been told that it is easier on your engine in cold weather. Is this so? Also I am concerned about the synthetic oil eating any seals or doing anything adverse to my engines' internal parts. Is there anything about synthetic oil that I should look out for?

Just put in some valvoline premium blue 5w-40 and noticed a quieter engine on start up in mid 30's, it actually seems faster, and when it's started in the morning I noticed the oil get's to the turbo faster.

Actually, in a 1996 test, Consumer Reports tracked 75 NYC cabs and found no real difference in performance between syn and dino. I mention that only because they made a caveat that "Big-city cabs don't see many cold start-ups or long periods of high speed driving in extreme heat." This seems to answer your concerns.

I cancelled my subscription to Consumers Reports some time ago because they've gone "green" with a strong lean to the left and I can no longer trust their product evaluations to be unbiased. As for oil, I am strickly synthetic as my driving conditions in AZ are severe.

While we're on the subject of syntenic oil (5W-40)...and the fact that I'm too lazy to dig through countless back threads to find the answer. Can I run that light of an oil year round? I can clearly see the advantages during the winter...but I'm worried about the summer. It gets over 90F for weeks at a time with 100F for a week or two where I live...so summer heat would be an issue.

Some will say (me that is) that synthetic fluids flow better upon start-ups and better lubrication year-round is better. As well, the high heat protection of a synthetic for your turbo bearings is a GOOD thing.
Just use synthetic oil for the benefits of using and not because you want extended oil drain intervals. Use a Motorcraft or Racor (OEM) oil filter and change on schedule and your motor will amaze you.
I have 139,000 miles with 100% of the parts my motor was built with... but I think that my dieselsite.com coolant filter has a lot to do with that along with my conservative oil change program of synthetic oil and Motorcraft/Racor oil filters.
