That additive is for the green anti freeze.
A lot of the newer trucks have the gold colored stuff that doesnt need the
additive

Kathy, Two items not hit...oil may turn black very quickly. Don't
worry, the harder the truck is worked, the sooner the oil changes
color. I use the Ford filter and Rotella T 15W40 and change it every
4500 miles.
Second item...if the engines idles VERY erratically upon start-up,
don't turn the engine off, the computer will sort it out in a few
seconds. This will happen more often as the weather cools and maybe 1
in 200 starts in warm weather.
I change the fuel filter every other oil change and keep a spare with
me if I'm traveling. I add the coolant additive at the same time.

I do not think the gold antifreeze was introduced until the 6.0L came
out. I believe that all of the 7.3L PSD engines required supplemental
coolant additive (SCA). I know my 1999 and 2001 did but the 2004 6,0L
PSD does not.

While not a PSD, my '02 V10 Superduty has the gold stuff and
specifically states its use in the owner's manual maintenance section.

Make sure its "gold" and not orange coolant

Nope, the last upgrade 2002 "525" PSD came with the gold stuff.
No additive required.
