I went all the way to the end of the internet and back reading about this issue...I still don't know the answer, but I use it anyway because it makes me feel better and I guess that is worth something....

If you are going to worry about staying with the standard oil change schedule then it is not worth it. If you are going to start doing oil analyst and change oil when needed then it is worth it.
Synthetic oil usualy cost about 4 times the price of regular oil. It should last 4 times as long. This is where the oil analyst comes in. It gives you a report of the condition of your oil at the regular oil change intervals insteat of changing oil.
This is standard practice for companied that have high dollar engines and equipment. Most have test ports that do not require the equipment to be shut down to catch a sample.
If you do oil analyst on the oil you are using now. You will discover you are wasting money with short oil changes. You will see more results if you spend your money on a better oil and fuel filter system.

djevans ...... here's a very close article like what I am referring to. It's not the original I remember, but the content is pretty much the same.
You are right about the 220,000 miles being deisel and maintenance. I will never own another gas truck in my life.

My first oil change on my RAM 2500 CTD was done with synthetic.
I did not notice any temperature change or gas mileage improvement.
I will send a sample off for analysis at my next change.
Synthetic is better than dino oil and I will continue to change it at factory intervals.
You will have to decide if added protection is worth the extra $$$$.
I use it because it makes me feel good and I use it in all my vehicles. (except my M-I-L's)
At my age, I need all the feel good I can get.

Lucky Mr H . . .
Thank you for the "link." I'm waiting for Lexus to release a vehicle with a diesel.  I now want, ONLY, diesel engines!
OK, re: the article: If you change your oil as recommended, you'll never "wear it out." Some will mention "oil shear" as the reason for synthetics. ALL modern oils will last the duration of the oil change interval.
We're not cold enough for cold flow to matter, we aren't running them hot enough to matter, or at high enough consistent RPM to matter. I will concede, the lawn mower might be high enough continuous RPM to merit some thought. But then, I change it every 25 hours and it's already 10 years old. I want a new one anyway. The tires are worn almost completely off. Engine is like new! (still starts on first pull)
I want my "toad" vehicle to be diesel too! (not sure about my JetSki though)

It's still a personal choice. General knowledge seems to dictate that 2 identical diesel powered trucks, one using approved dino oil, the other using synthetic oil, worked for a length of time and for a number of miles will have almost no difference in fuel burn or maintenance costs. But, many owners use our trailer pullers differently than commercial operations. Different length of time between uses, different weather conditions, different times between oil changes etc. Therefore for those who believe the synthetics may provide a little more protection for their "beloved" truck even at much more cost, cannot be faulted. In the end it's still a personal choice. I use the regular oil in my cummins and will continue to do so (simply because at 12 quarts the synthetic costs SO much more), but the cars get synthetics. Make any sense? Does to me.

I look at it this way. Some guys take their trucks to a service center, dealer, or qwik lube place and end up paying $90 or $100 for an oil change (diesel). I use synthetic, and do it myself for $65 including a quality stratapore filter.

IMHO, if you can swing it, put synthetics in your baby from bumper to bumper, even the blinker fluid... 
I checked with the local NAPA store and they didn't stock any "blinker fluid". I assume this is the lubricant that goes in the turn signals. Is that correct?

Is it cost effective, I don't know! I use it in everything cause I THINK it is. In two cycle environment you get much less smoke.
Mfgs are using it in various driveline components. Some hi-performance engines, the Vet, comes with synthetic from the factory. WHY it cost more???
In some new engines they recommend Dino Oil for the first couple of changes before installing synthetic, WHY, break in? That tells me the synthetic generates less heat/friction.
Its highly used in hi performance products. It makes a differences on my snowmobile engine.
