If you have bearings no need to oil. Real tanks creek and squeak. The noise will go away as you run the tank and the dust/sand/dirt makes its way out.

You can oil it will not hurt anything. But I would recommend this only if the wheel is stuck and will not move. Oil will attract dirt to the parts but wet and dirty is better then dry and dirty if the wheels are not turning. The plus side regardless is it looks great and adds to the nature weathering effect as dust and dirt collect on the oil. I have used whatever has been on had in cases where I needed to add a little oil, usually simply motor oil. A small drop is all that is needed.

You could use powdered graphite used in pine car derby cars.

There are a few Dry lubes out there. Graphite being the old classic. One that was marketed towards mountain biking was Teflon with carrier that would evaporate off leaving a dry Teflon coating. I think it was called White Lightning.

That being said I'll be sticking to Rubicon99's advice. I'll lube as needed when loss off free movement is observed with whatever i have on hand.

For plastics (ABS), any PTFE or Silicone lubricant is safe. Lots to choose from and cheap.
From what I've read, "ester and polyglycols " based lubricants are NOT safe for ABS. So also be careful of what you use on your steel gears in an ABS hull.
