I decided to live dangerously and run my brand new MS3 out to 5,000 miles before the initial oil change, and guess what? No oil dilution issues according to Blackstone. And the same has been true of the 20 subsequent UOAs- even after I switched to a 7,500 mile OCI at 77,000 miles.
Like you, I guess I'm really driving a ticking time bomb...
I'm even more careless, I go for the entire VW recommended 10,000 miles. I guess I should start an "engine replacement fund" as it should go any day now.
For all the issues the engine in my car is reported to have, catastrophic failure is beyond rare. Even the upgrade and tuning path is so well defined and tested that modified engines typically don't even fail that frequently.
My car is maintained per manufacturer spec, no more or less, although I will be changing the cooling and gearbox fluids in the near future ("lifetime").
