I made 40K wth my CC, no issues ever. I do drive this car very hard, and it sees redline several times a day. I think aggressive driving with high rpms for extended period helps.
I do not mind ordering top notch oil at all, nor I consider $103 to be expensive for 12ltr of M1 5W30 ESP.
I never had misfiring, oscilating rpm's etc.
On my wifes Tig, we relaced manifold 1K after we bought it. I do think main culprit there was Castrol 5W40 that owner used previously.
My driving style is aggressive. There was something wrong with that engine, even the dealership mechanics never saw it that bad and had Germany involved. I currently own a Q5 2.0T without issues (as of this posting).
Yeah could be that specific engine. I bought CC used, now have 62K, use High-SAPS oil every time, but never experienced what you did.
I am going to try Mobil1 ESP in my car since it is out of warranty and then do UOA. If TBN stays within limits I will start using it in Tiguan too (it is under warranty).
What was your experience with Castrol LL-03?
