I'm not too sure, but it probably says on the can. I have used both latex and oil based paint; and I can't stand oil-based paint. It's more difficult to work with than with latex paint. Painting with latex is fun whereas painting with oil-based paint was a total pain in the ......... The fumes are so strong you can't use it indoors unless the area is well ventilated. The paint drips off the brush before you get it to the wall because the the paint is oily. Imagine painting with motor oil. It's almost that bad. I'll never use oil based paint again.
its nothing like painting with motor oil, more like molasses
I have been painting house's/ skyscrapers/oil rigs for over 25 years. & yes you can use oil base paint over latex, 1st you scruff the existing paint with sand paper, then dust, put 1 coat of primer(Kilz primer is the best I have found to use) over latex paint a lite coat will do. let dry & now your free to start painting.

Yes, you can.
Just paint it on if the latex is adhering well.
You can always paint latex ( water based )over an oil based paint as the latex just dries on the surface. However don't paint an oil based over a latex paint. Oil based paints need to absorb into the wood or other surfaces or it will just dry and flake off. For more information on the differences and when or not to use a latex or oil paint please see the following article. . http://www.ehow.com/how_4713170_between-latex-oil-base-paint.html
No, they will not mix,
Yes it will.
No, you either need to really rough up the oil paint with fine sand paper, or put a base coat on before you paint with your Latex paint. If you don't your Latex paint won't adhere.
no
yes. However, you cannot use an oil base paint over a latex primer. If you change your mind on the paint, you must strip the paint before you use an oil based paint on the primer.
Not if the melamine paint is oil (alkyd) based.
If I was going to repaint this, then I'd remove both the latex and the old oil base with a chemical stripper. Then re-prime it and paint.
Don't mix them, your inviting trouble
Yes it can.
