God bless Toyota for going to a Cartridge style Oil Filter!!
Hmmm 
sorry man but I work with mechanics daily and have for many years. I am actually in Ireland right now working with mechanics internationally and I have NEVER heard the logic that you should not use synthetic until 40K miles *LOL*
In fact I build engines and am practically a mechanic myself without an ASE cert, I simply do not like being a mechanic for a living as it takes the fun out of it, I rather teach mechanics electronics which is what I do for a living besides the LED work I do
Synthetic comes in the oil weights recommended by Toyota, such as 0w20 - 5w20 - 5w30 - 10w30 +++ Synthetic is not a mythical oil weight that is different than standard oil. Cleatus at the local gas station service center may have given you the wrong info sorry man!

aww should of wore your flame suit but its too late now, DUCK!

# The lower friction may make them unsuitable for break-in (i.e. the initial run-in period of the vehicle) where friction is desirable to cause wear. Improved engine part machining has made break-in less critical than it once was though. Many modern cars now come with synthetic oil as a factory fill.
# Potential decomposition problems in certain chemical environments (industrial use dominantly)
# Potential stress cracking of plastic components like POM (polyoxymethylene) in the presence of PAOs (polyalphaolefins).
# Potential on some older pushrod race engines with roller lifters for the roller itself not to spin with camshaft movement, but rather slide while the roller itself remains either stationary or at a lower circumferential speed than that of the camshaft lobe[citation needed]
# In July 1996, Consumer Reports published the results of a two year motor oil test involving a fleet of 75 New York taxi cabs and found no noticeable advantage of synthetic oil over regular oil[2]. In their article, they noted that "Big-city cabs don't see many cold start-ups or long periods of high speed driving in extreme heat. But our test results relate to the most common type of severe service - stop-and-go city driving." According to their study, synthetic oil is "worth considering for extreme driving conditions: high ambient temperatures and high engine load, or very cold temperatures." [3] This research was criticized by some because most engine damage appears to be caused by cold starts, and their research method may not have included enough cold starts to be representative of personal vehicle use.[4]

Hahaha you pulled that off WIKI, unless you know what your talking about, do not quote a wiki *LOL* Here I can quote a wiki just as easy hahaha And were on your wiki of knowledge does it say not to use synthetic before 40K miles? Seriously, just give it up! Your way off track with your knowledge of motor oil and info.
Advantages
The technical advantages of synthetic motor oils include:
Measurably better low and high temperature viscosity performance[citation needed]
Better chemical & shear stability
Decreased evaporative loss[citation needed]
Resistance to oxidation, thermal breakdown and oil sludge problems
Extended drain intervals with the environmental benefit of less oil waste.[citation needed]
Improved fuel economy in certain engine configurations.[citation needed]
Better lubrication on cold starts

I'll be adding synthetic...
After my first oil change.
Your evidence is rumor and opinion. I am 110% comfortable switching to a lifetime of synthetic after the initial 3500 mile break-in.
We can have this discussion for the next six months, but I have read my share of reports and opinions and I am quite comfortable going synthetic once the manufacturers oil goes south.
Regardless of what you put in there, you probably will agree that these truly amazing Toyota engines will surpass the 200K mark with only supporting maintenance.

Silly...
Wear is never a desirable action - this was not written by an engineer!
By the rest of your supporting evidence, it is clear that I would want to use synthetic.
As an aside... NYC cabs which are rented by the driver are cycled through several 10 hour shifts. It is true that a NYC cab probably doesn't remain idle for long. Your point is irrelevant.

I am chuckling as I give my xD a great big drink of Mobil! in celebration of it's 2000th mile!
No fear here!
