I've just got my old LEGO Technic motor from my 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 SAE 20 but that only seems to be available in the USA. Any suggestions for the UK?

Start with a food grade mineral oil something like this: picture– Dan1138Oct 18, 2020 at 22:08

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!– DerekOct 19, 2020 at 15:28

Hi Derek, is this your motor? (bricklink.com)– UliOct 19, 2020 at 16:10

Yes that's the one– DerekOct 19, 2020 at 16:46

@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.– TonnyOct 21, 2020 at 10:46
