So it’s old enough to have an oil port (yay!) which should make it easier but my questions are thus:

1) What oil to use and
2) How much?
3) Also- I don’t have any oil to hand but I do have a grease gun ready to go- is it worth putting this in in instead? What would be the implications?

Thanks!

3 in 1 used to be the oil of choice, two or three drops every couple of weeks.

No, deffo not grease of anything thick – it need to be light oil.

I guess that 3-in-1 comes in a convenient dispenser bottle too..

sae 30 or 20 is recommended
