I reccomend no lube on the X-ring chain. The double sealing surface keeps the factory lube in and any applied lube out. All chain lube does is attract dirt causing the chain and sprockets to wear faster. I took my last set off with no lube at over 25,000 miles and the chain and rear sprocket showed no visible wear and the front sprocket showed such a small amout of wear you almost couldn't see it. They are hanging in my shed as spares.

I learned all I need to know about life by killing smart people and eating their brains.
