Oil Change (Update)

I had a bitchin bike session tonight. The sweat was pouring off me.

No, the Tacx still isn't working properly... but finally a verified replacement part is on the way - I've been using it in 'manual' mode.

It occurred to me that I don't even remember the last time I lubed my chain.

It would have been at least 500 (conservative) km ago.

Update:
In the shower this morning, because that's where I ponder all of life's mysteries, I was trying to recall exactly the last time I lubed. And I can't for the life of me remember, if I used wax or oil. And what if it was wax, and I put oil on top - or vice-versa, what's that going to do... oh, crumb. I say toss the whole thing and start with a brand new bike. What's a boy to do?
