Hmmm, based on that logic, does the owner's manual mention anything about carbon buildup on the intake valves? Are we supposed to pretend that doesn't exist either? I've seen enough pictures of the FSI's to not be too naive, and I doubt VAG has done anything with the TSI's to solve the problem (i.e. injector in the manifold that has a bit of a duty cycle to wash the intake valves periodically).
If you're worried about intake valve buildup, you should use a low-SAPS 504 oil like Castrol SLX Professional LL03. There is a Lubrizol paper that's been posted here before that shows a big reduction in these deposits by using something like this.
504s would be a somewhat good choice for reducing I/V build-up as most of these deposits come from oil seepage past the valve guides. TSI engines have a redesign in this area as well as others to increase combustion efficiency and decrease blowby and other maladies relative to the FSI engine. Evidently VW is rethinking DI with its new 1.8T slated for the next MQB platform. It, like the Toyota DI engine, will have a secondary injector system in the port, supposedly for reasons NOT related to deposits. Ok, sure

This engine can be tough on oil, and a 504 would NOT be suitable if respecting the OE recommended 10K OCI due to fuels dilute etc. But who here respects that interval anyway

Neat car, got one myself last November. For the money, its hard to beat the performance and quality. Currently on GC til 5K, then maybe RLI. I too did changes at 750, and 2.5K miles before going to the GC. Lots of glitter in the FF change so I'll have to agree that there was a bunch of metal swarf in that OCI. Call me what ya want, but I'm still old school when it comes to new engine break-in OCIs and seems others are too. T. Dyson followed the same regime and gave this a thumbs-up too. He has the same engine in his GTI and knew that going 10K before ANY changes would not be the best thing to do. I'm at alittle over 4K and don't lose any oil at all.
