Hi I've just got my old lego technic motor from the loft. It works but squeals in a way I don't remember it doing (35 years ago). I assume some lubrication would help and I've seen references to 3-in-One SAE20 but that only seems to be available in the US. Any suggestions for the UK?

  • Start with a food grade mineral oil something like this: picture

  • Would standard 3 in one (which I already have) do the job or is that too thick? A full bottle of the food grade stuff at £8 seems excessive when I only need a drop!

  • Hi Derek, is this your motor? (bricklink.com)

  • @Derek Composition of 3-in-1 oil products can vary a lot. Some are safe (like the SAE20), others will eat the ABS plastic LEGO is made of. Without details on the exact brand/type of oil you have at home, we can;t advise if it is safe or not.
