Reply To: Using Motor oil for clock lubrication…

Hi Tom,
I moved this as it wasn’t really a hint or tip, I hope you dont mind. I think it will get a better response here too.
As long as that motor oil is not multigrade where it will contain cleaning agents etc and the viscosity is ok then I dont see why not but like most things, until it has been in a clock and running for a minimum of 3 years I would be wary. Sometimes it is better to stick with the known rather than the unknown but I do know they have been using slick 50 for mainsprings and it does seem to be very good at preventing sticking and keeping the spring movement smooth.
Paul.
