Correct coolant
Your truck takes the regular green ethylele glycol coolant and you need to add the FW-16 additive in the correct proportion to prevent cavitation of the cylinders. The additive is very important on that engine.

joe is right although there is another factor in choosing the right coolant. The ethylene glycol must be low silicate and conform to ASTM-D4985. If you decide to use a 50/50 pre-mix, there is another ASTM # it must conform to but I'm not sure on the number. I think it is ASTM-D6210, but I'm not sure.The ford part # for my 1990 7.3 idi is ESE-M97B44-A. I don't know whether that part number is still valid for a '93.

Low silicate coolant is certainly preferable to the regular stuff but I'm pretty sure that your truck didn't leave the factory with low silicate coolant in its radiator. Threrfore, it wouldn't be the end of the world if you fill it with Prestone off the shelf.
The important issue here is the proper proportion of the FW-16 additive. The silicates may sandpaper your water pump seal to death, in which case you'll need a new water pump but the lack of the additive will cavatate your cylinder bores to death from the inside out, in which case you'll need a new engine.

Absolutely, the nitrite solution (FW-16) is critical but also you need to get a low silicate antifreeze. A low silicate antifreeze will keep the waterpump seal in good shape (although if you add too much FW-16, it will damage the waterpump seal) and you also will not get the "green goo" syndrome (silica gel).
