If it sits a lot synthetic will drain off important places. 10-30 Rotella, Delo, etc..... People are getting silly about oil anymore, additives etc..

You may have a point there...
Quote:
Zinc Concentration (ppm, ICP) : Though viscosity is critical in terms of wear protection, it does have limitations. Component loading can exceed the load carrying ability of the oil. When that occurs, partial or full contact results between components and wear will occur. Chemical additives are added to the oil as the last line of defense to control wear in these conditions. These additives have an attraction to metal surfaces and create a sacrificial coating on engine parts. If contact occurs the additive coating takes the abuse to minimize component wear. The most common additive used in internal combustion engine oils is zinc dithiophosphate (ZDP). A simple way of reviewing ZDP levels within an oil is to measure the zinc content. It should be noted that ZDP defines a group of zinc-containing compounds that vary in composition, quality and performance. Quantity of zinc content alone does not indicate its performance. Therefore, it cannot be assumed that oils with higher concentrations of zinc provide better wear protection. Additional testing must be reviewed to determine an oil’s actual ability to prevent wear.

A Group III synthetic should drain off less than a Group I/II dino or a Group IV (PAO) synthetic. Most commonly available OTC synthetics are Group III oils.
See BITOG Reducing wear at startup on a low service engine
That’s a pretty broad generalization.
A good starting point in any motor oil is the quality/type/amounts of base oils and complementary additives used in the oil as well as the know how in formulating a balanced lubricant.
Not all Group II, Group III, and Group IV motor oils are created equal. Some perform better than others and in some cases its application specific as well.
In the end, the trump card to determining a motor oils performance is with a Used Oil Analysis (UOA) report.
There are many Group II, Group III, and Group IV motor oils that return outstanding wear numbers in UOAs.
As mentioned, supporting data can be found at BITOG

i ran synthetic in my 440 powered race car (MP .590 solid cam) until I had to replace the cam for wiped lobes the second time. By then, I figured that it was best to go back to regular diesel oil.

I had ran Mobile 1 10w-30 for years without problems, but a few years back they changed it, removing most of the ZDDP additives (same issues with the standard oil), and I wiped out a cam lobe! If you use a synthetic (or any "energy efficent" oil) with a flat tappet cam, make sure it is one that still contains a good amount of additives, or add additives to your oil.
