I know that some oil painters add mineral spirits (turpentine) to their oil mixes. How do they actually add it using a brush, mixing spatula? How much should be added and to what consistency?

Talino,
I do not use mineral spirits. I find that the colours become to shiny.
When i need a diluted paint i use some English Destilled Turpentine from Windsor and Newton.
I dip my brush in it, dry the brush a little on a todd and pickup the paint.
It dry's verry quickly and with no shine.
Further it smells better then turpentine.

I don't use turpentine as a paint medium but as a brush cleaner. There are some odorless brands available that I use for that now. For a flat finish Dorland's Wax medium is very useful at 60% paint with 40% Dorland's as the aproximate ratio. Extra oily paints I deposit on an index card to let the card soak out the excess oil then I transfer the "drained" paint to my wax paper palette. With transparent oils, like greens, the Dorland's is only about 30% of the ratio. It can also be brushed over a completed section, after it's dried, to tone down a sheen.
Best!

Some people mix in with a brush, others use a palette or painting knife, it's pretty much up to you. One thing I would definitely not do is use a good detail brush to mix paint with (except for tiny touches where you're just picking up a dot of this colour and that colour) as this will wear them out much faster than if you use them for applying paint only - some pigments are quite abrasive.
Depends on the consistency you want. Some people paint in thin glaze-like layers made of oil paints thinned with spirits (Gianfranco Speranza paints this way from what he's said) others use the paint pretty much unthinned, brushing it out thinly on the surface of the model.
Turpentine should generally add to the sheen of dry oil paints while white spirits/mineral spirits will do the reverse. But this will depend heavily on the brand and even the specific colours you're using anyway as no two are alike.
From a safety aspect - particularly if anyone paints in their bedroom - WS/MS are usually quite a bit less toxic than turps, particularly the low-odour varieties (OMS or odourless mineral spirits) like W&N's Sansodor for example, but there are many hardware-store varieties available that are cheap and work just as well.

Hi Ric, when painting models in oils there are better ways than wax medium to ensure a flat finish which I'd recommend you try as all of them will aid achieving a smooth finish but especially with coverage - any added medium will reduce opacity, especially at 30-40%!

For thinning I use only and only the Quick drying petroleum essence from Lefranc. It gives me the matt effect that I need to paint all the surfaces that need this kind of finishing and no other medium is good as this one.
I add it from one to some drops to the oil colour obtaining the consistence that I need. Try it.
