What makes you think it will fail? That is what approvals are for. Today when timing chain/guides fail it is not oil, it is inherent design problem.I've had flat tappet motors over the years with aggressive cams and valve springs. They had to have plenty of ZDDP to survive, sometimes approaching 2000 ppm. In the modern vehicles that I service that have long tricky timing chain paths I am weighing using higher than recommended ZDDP for their known wear issues. What cost's more to replace/repair. Timing chains/guides or catalytic converter? I need to do that research.
For example, timing chain on my BMW is not an issue, but Bank1 and Bank2 cat converters are around $1,400 each.
On EA888 first generation timing chain guides were an issue, and there was no oil that would help other than updated timing chain tensioner and guides.
