Question synthetic oil question...

Should you log a minimum number of miles before switching to synthetic based lubricants of is it acceptable to introduce them at the first 1k service??? I have always heard in the past that carbon based lubes should be used at least until the "break-in period" has expired...

Common myth. Engines actually need MORE protection during break in, due to tighter tolorences. Most companies don't use it due to added cost.

Harley CVO bikes come with Synthetic from new. As do all these listed vehicles, including S&S.

Acura RDX, Aston Martin DB9, DB9 Volante, DBS, DBS Volante, Virage, Virage Volante, Rapide
Bentley Azure, Brooklands, Continental Flying Spur, Continental GT, Continental GTC, Mulsanne
Chevrolet CR8 and COPO Camaro

Citren DS3
Holden HSV
Lexus LFA
McLaren MP4-12C
Nissan GT-R
Peugeot RCZ
Vauxhall VXR8
Viper Motorcycles

Interestingly, Hastings recommends conventional motor oil instead of synthetic for replacement ring break-in.

I started using Synthetic at the first service. No problems, 45,000 miles later.

The previous owner switched to synthetic at 1k miles,it was using a quart every 500 miles.The dealer checked it and did some warranty work,added synthetic by the time I got to Daytona(525 mi) it was a qt. low. I've been using 20-50 w dino oil and now uses 1/2 qt per 5,000 miles. 19,000 mi no problems. I may change at 25k service,like I did with my BMW(Amsoil)

I switched to syn the day after I got the bike home, oil consumption is more tolerance related than the type of oil,and varies from engine to engine, to add to the list, Corvettes, Porsche , BMW, MB, AUDI, all come factory filled with Syn.
Let me add, oil consumption occurs usually when the engine is cold, oils perform and protect best when they reach operating temperatures, that's one reason I always let my vehicles idle for a while before I pull out in the morning.
The new AMGs MB don't give you full power till it has reach operating temp to protect the engine,the ECM electronically controls horse power and rpms while temp is not at NOT.

I switched to Drag Specialties oil and I've been pretty happy with it. I'm down south where it gets HOT and I've noticed good temps.

BTW, my Z06 Corvette came from the factory with Synthetic. My Cobra did not though. Shame on you SVT!
