No lifting Jack should be this delicate that just the wrong kind of oil could make it fail.

Interestingly, a different product from another manufacturer this has been compared to has very similar maintenance instructions.

All mechanical parts need to be lubricated from time to time. You must not do any maintenance in your tools lol
