It's not the topcoat that's important, it's the surface the primer needs to adhere to.
Besides a few shades of black, white primer will reflect more light back than a gray primer under a paint color that doesn't cover well. Gray is often used under dark reds which would normally require several coats of paint to cover, The lighi that would normally be reflected from a white primer underneath the paint is, instead, absorbed by the gray primer, giving the illusion of an opaque surface. White primer is used under any light paint that covers well. It can also be tinted to the color of many off white or pastel wall colors to help ensure coverage using fewer coats.
It is not necessary to use a primer for interior walls, but using one helps with adhesion and smoothness of the paint.
This depends in large part on what paint or finish your are going to cover your oil-finish with. First, you need to determine, if possible, if your existing oil paint contains lead. If the oil paint is over 30 years old, you should assume that it has lead and the paint should be removed before continuing. (See your local codes). If you are painting the surface with an oil-based paint, simply rough up your surface with 220-grit sandpaper, clean and paint away. If you are covering your finish with latex, you should scuff the finish with 220-grit sandpaper, clean it well and apply two coats of latex primer before applying your final coats of paint. If you are applying wallpaper, we suggest that you scuff up your oil finish, apply two coats of latex primer and allow it to dry for at least 3 days before papering.
. Acrylics ARE water based.

There are many good latex primers that will work under oils.
Primer is under the paint.

Latex paint can be used as a primer but the results may not be what you want. Primer is less expensive than latex paint and has special qualities that create a seal and help the finish layer of paint adhere better. In the long run you will save time and money by using the correct product for the job.
All the information I read on Tinners paint refers to it as 'anti-rust' exterior metal paint . - I certainly wouldn't put a latex primer on anything outside. I would use Kilz original as a primer.
paint it with a universal primer such as "BLOCKER" brand first Yes, you can. My preference is to use oil base primer under latex (water base) paint, because in my experience the oil base primer lasts longer. It stays stuck to the wood longer. I think latex primer is basically bogus. I have wasted a lot of time using latex primer and it comes loose and I have to sand it all off and use oil base primer. Latex primer does not work. Just like latex paint sticks poorly to bare wood. Latex paint does not have much "stick" (also called "tack"). It is a thin sheet of rubber, and there is very little "tack" to it to keep it glued to the wood. Latex peels off readily, once you put a knife under an edge.
Yes, the water borne latex paint manufactured today can be covered successfully with nearly any finish imaginable, including an alkyd primer. However, if possible I would exchange the alkyd with any water base primer/sealer. Costs less and the fumes aren't as offensive.
Alkyd Enamel is really old school primer. I personally would sand it with 400 wet/dry and put a coat or two of an epoxy primer over it then you can put just about any type of paint on it. If you don't want to do that, probably your best best would be n Enamel top coat , You can still get Automotive Enamels but they will be expensive because the EPA is really cracking down on the solvent based finishes. Color selection may also be limited but they are out there. And even if you use an enamel , you should clear coat it with a Urethane Clear. IT helps protect the base coat from fading and gives a great gloss when buffed. I have painted a lot of cars with Enamels and they go on fairly heavy so watch out.
