Rover 5 gearings lubricant : Which one to use?

Hello

I bought a Dagu Rover 5 (4 Motors 4 encoders). I notice that gearings make some noise. There is a little part of lubricant delivered with the rover but it is cheap. What kind of product can I use to do that ? (in other words, What type of lubricant to use for the gearings?)

Thanks a lot by advance

Thanks a lot for the answer

I think I will use Teflon based grease (look at google and found that it was the grease used in car modelism)
