I read Nova's article yesterday and was wondering what some of you 'old heads' here think about it. Since they don't make Singer lube any more like the original formula, what do you use other than petroleum jelly? And if you use petroleum jelly how do you get it in the grease tubes? Does it come in syringes? Can you tell I'm completely ignorant when it comes to machines? I have a FW that needs to be lubed and I don't want to mess it up. I do have a tube of Singer lube that I bought fairly recently and now I'm afraid of using it.
