Porsche - good sub for coolant

[sasilverbullet]

Porsche says, yada yada yada, only use theirs, of course it's a fortune...

Found someone that said the only dif between the Porsche and VW/Audi is some eco specs.

Found this on Amazon - https://www.amazon.com/gp/product/B077P3XQQD/ref=ox_sc_act_title_1?smid=ATVPDKIKX0DER&psc=1

Seems ok to me, what do you guys think?

Can I just use it to add a little to whatever's in it?

I have bought and used it, if it meets the spec I don't see a problem. Being premix you can add as much as you need to whats in there.
VW TL 774 F is G12+ and fine for your 03 Porsche.

You'll be fine with the OEM brand Euro II. Porsche coolant is just another euro Si-OAT just like the parent company VAG uses, and practically every European car company. Porsche even uses the same specs for their coolant as VAG, so besides maybe dying it a different shade it's very hard to imagine it's any different than VW/Audi coolant.
