I was lucky a few years ago, a friend of mine that is a diabetic, gave me a carton of 50 syringes with needles. I fill one with a little gun oil and place the needle right were I want a tad of oil. I use oil where it is needed, but sparingly. Put the cap back over the needle and use it whenever needed.
