You planning on building fertilizer plants on Mars?
You planning on building chemical manufacture plants on Mars for all of this?
Sure, why not? Maybe not immediately, but eventually. This is after all a colony. It's not a tourist resort.
What resources does Mars have that you could use to synthesize lubricants?
You can't just magically turn vespene gas into 30 weight oil to lube your engine.
Well, I don't know about vespane gas, but one can synthesize methane gas from material readily available on Mars. There's hydrogen in the water ice and carbon in the atmosphere (which is mainly CO2). If you can get methane, presumably you can get other kinds of hydrocarbons, too.
