Ok, after reading everything, if according to Lubrizol, low saps oils reduce intake valve deposits, why did the UK Jetta have them running Edge 5w-30? Likely the long 19k miles interval was an issue.
Right now, I have a 2010 TSI w/500 miles and I don't know what to do. I'd run a cc, but that would rip into any warranty claims. I'd like to have some faith that VW improved the system, but who knows. Extended warranty would not do anything to clean the valves, until it misfires it's an aesthetic issue!
Fuel quality and OC intervals will have to be the solution available. I plan 4 month intervals, maybe 3-5k max for me. I have a bunch of different synth oils to use, they should not be stressed, ordinarily.
I have Top-Tier fuel here, that's what the manual calls for so I guess that's what I will use exclusively. My Tiguan sat on the lot for 8 months, so I hit it w/2 bottles of Techron right off the bat, and it did wake the engine up! I usually run 2 cycle oil in my gas, do people think this is a good idea? Seems like it can only help.
