Would gun oil work for bearings?

Do you grease the levelwind? I see it as a gear thus it should be greased. When I got my new MGX the book says to oil the crazy thing. Which is correct?

There a four different lubricants that I use in fishing reels.

Dry Teflon Lubricants � For the last 2 months, I have been using a dry Teflon lubricant from Xtreme Lubricants on spool bearings. After cleaning out spool bearings and lubricating them with hydrocarbon based oils, freespool times of 30 to 60 seconds are typical. Lubricating these same spool bearings with one of these dry Teflon lubricants will increase the freespool times from seconds to minutes. Larger spools with a great deal of rotational inertia can spin for up to 5 minutes when the bearings are lubed with these newer dry Teflon lubes. Hydrocarbon-based oils can form can actually form a hydrodynamic wedge (like a standing wave on a very small scale) in front of the balls of the bearings that will actually slow your spin rate. The improvement in freespool time is dramatic! Another reel tech and I had independently tried this product, saw the improvement, and decided in a microsecond that we were going to use this product in our own personal reels. At issue is what to do for a customer. Corrosion resistance is still a concern, but even my tried and true Corrosion x does not last forever. So how good (or bad) is the corrosion protection from these dry Teflon lubes? I will have a final answer for you next year. For me personally, I know that better freespool will give me longer casting distances, and longer casting distances will catch me more fish.

Curados are much easier to work on from seeing all the parts from the revo.
