Does Dexox1 Gen2 suppose to lower timing chain wear? Or just for LSPI?

Both.

GM has developed four new engine tests for this updated specification:

New General Motors Oxidation & Deposit Test (GMOD) verifies the improved oxidation and deposit control characteristics.
New Stochastic Pre-ignition Test verifies the added protection for turbocharged engines and pre-ignition concerns.
New Turbocharger Deposit Test verifies the added protection for turbocharged engines and minimizes deposit formation, which ensures optimal performance during engine life.
New Aeration Test (bubble control) ensures the air bubbles in the oil dissipate quickly to improve oil performance.
New Timing Chain wear (stretch) test.

It could be that oils were already good at timing chain and LSPI issues, but the dexos1 Gen2 tests prove something to us.

That answers my question. Thank you.

^ this, recognize.

I have never had timing chain wear as for as I know. Some engines over 300K.

I have read that letting the oil level get very low (or not doing changes at recommended OCIs) will induce timing chain stretch or failure in some makes.


Can't EVER imagine that happening to a BITOGer, though. grin

DI and turbo+DI soot has been blamed the most. Its a very small grit that makes it past the oil filters, like around 1 micron or less in size, and filters only get out particles greater than 20 microns in general:
"Chain wear is caused by GDI soot, a carbonaceous contaminant unique to T/GDI engines that causes accelerated timing chain wear. It has been proven that advanced lubricant additive technology can have a positive impact on both LSPI and chain wear."---Lubrizol statement, and https://phys.org/news/2016-07-gasoline-direct-green-choice.html and https://link.springer.com/chapter/10.1007%2F978-981-10-7185-0_6

Keep intervals to 5kmiles andmget the soot out.

Could a timing belt hold up to the same conditions? There are also the guides and sprocket gears.
