100%Many TDI engines of varies flavors that go into the 300k-400k range with 10k to even 20k OCIs. To short of an interval has actually been shown to increase wear due to the additive pack in the initial new oil. A few UOI on TDIclub forum that has found even a 20k OCI was still in good standing.
Anyway, each their own, I figured I can replace the engine for about the same cost of to frequent OCIs if that rarity does happen.
There's hundreds of threads between TDI club and Bob is the oil guy of people doing oil analysis and hitting 20-30k mile oil changes. Again, research it. You seem to ask for a lot of hand holding on this forum at times.I would love to see some scientific data on that for sure if available because I'm no spring chicken and never heard that before. In the meantime if anyone wants to buy my used oil at my next change I'll make you a good deal.
In reality it wouldn't change much at this point anyway as it's not my daily and after the Allroad we ordered comes in it will be down to a single highway commute once a week to keep it in service and then the tow duties to track weekends, probably won't even have 7000 miles a year.
