Chain life, size and oilers

My V Strom needs a new chain, has 11,000+ miles, which seems comparable to my other chain driven bikes. I plan to by new sprockets as well (to change gearing).

It seems intuitive that a rig would be hell on a chain? Have others found this to be true?

I am considering a couple alternatives

The Strom has a 525 chain. I can "upgrade" to a DID chain and perhaps to a heavy duty 530 chain (need to verify sprocket availability).

Also, I could add an oiling device like a Scottoiler. I have never used one, only heard of them, but then not that used to chain driven bikes.

Any thoughts or suggestions?
