Dirty oil seems to do a number on the screens in some VVT systems and some chains are prone to stretching on the wrong oil.
So oil is important. I do think on some cars going over 10k would be ok, but you must be very diligent in checking the level...and using a high quality product....I think the mobil 1 is high quality. But I personally wouldn't go that far.
M1 doesn't exclude engines with VVT from their 15K warranty with EP oils. Clean engines is a strong point with using M1 oils, so chains and valve guides are better protected when sludge and heavy varnish aren't present. My Fusion has VVT and the cyl head and timing chain are like new clean at 10K OCIs.
You using Mobil 1 EP? I haven't tried it, but I would consider it. And I haven't tried extended drain yet either - although I'm planning on going 8k on TGMO, that I have in it now.
I like Mobil 1, I'd be willing to give the EP a try.
