You're going well over 2x longer than most believe is even "possible" with your engine. If you believe everyone, your engine will only survive a few hundred miles longer than the automaker's warranty and explode.... There will be issues with cam phasers, timing chain guides, etc, etc yet the engine oil is still very much viable according to UOAs. These UOAs are a pesky thing ! Suggestions are always to have them done but don't believe or accept them when they go against conventional (here) wisdom !
