Do I want to use oil to anneal or just heat it up with a mapp gas to a color and let it cool?
Heat to glowing orange color & quench in oil to harden. Clean or sand to bare metal, then heat to a light blue color & air cool to anneal. mapp works better, but can be done with regular propane & a good torch.

You want to heat treat (harden) the ejector tip NOT anneal (soften)... You can use
motor oil (used or new) or salt water. I've even heard of somebody using glycerine
but I personally haven't tried it...
