Knowing Porsche and how they approach things I prefer not to rock the boat whilst under warranty. Just saves an argument, and a £1,400+VAT washer pipe repair bill when they say "ah, you shouldn't have used that" and I then have to take them court for "an obvious design fault" and leave it to the judge on the day to decide.
There's that "Porsche warranty monster" raising its head again. Porsche really have mastered the art of upselling their products and services by creating this absolute fear, to many people, towards anything non Porsche approved. It appears some have been brain washed into "Porsche" screen wash now! Be careful what polish you use on the paintwork, if its not approved they will wriggle out of any paint defect claim. Thank Christ you don't have to pay for air, otherwise people would be buying "Porsche air" to ensure their tyres are inflated to "approved" standards.

Porsche winter concentrate (as shown above, £6 delivered) is 1 litre.

I would recommend a stronger mix than you might otherwise think is needed as the rear washer pipes are particularly exposed, wind chill being a factor.
The pipework has a pressure relief valve designed to literally blow off at 5 BAR pressure. As PGB regard this incident as being due to "external influences" i.e. cold, YOU are at fault, per Porsche GB, and it might cost you £1000 - £2000 to have this rectified.

But... some OPCs disagree with PGB and have argued with them that it's a design fault. Depending on your relationship with your OPC they may repair this FOC. Mine did so recently. To stand a better chance, use only Porsche washer additives. My OPC asked, and I had towed the line. I don't know how they would test for this but they may well be able to.

I'm now mixing 1:1 for the Midlands UK which protects down to -17C. Choose your mix wisely. Porsche's green washer fluid can still be mixed in with the winter concentrate as per your owner's handbook.

Thanks so much for the explanation and additional picture. Based on what you said then, and I’m in London - better to err on the side caution - mix one bottle of Porsche stuff plus equivalent amount of filtered water (i understand there’s a 3.5 litre capacity) and also buy a bottle of the green stuff that’s picture here and add a splash of that?

Or match the volume of water plus green stuff - to the amount of Porsche washer liquid? Ultimately it’s better to put in more of the Porsche washer fluid because of the antifreeze :)

Thanks again :)

That's the summer stuff, t'other is winter with antifreeze. You don't need both at the same time.

The green stuff is just one top of bottle partitioned squeeze per full fill.
It's a window cleaner only, not antifreeze, and your manual will explain you can add it as well as the winter concentrate.
I do, as it helps clean the windscreen.

Wow, this is way over the top. Sort of happy not to have known - per glass this stuff is more expensive than a decent red wine!
Fortunately no issues with off the shelf windshield wash in our 2 Macans over the last 3 + 2 winters.

Amazon currently has good deal on Sonax Summer Screenwash which appears to be similar if not identical to Porsche product = approx 27p per litre (when diluted)

I was looking at the picture higher up, £15.30 per 250ml. Have only now noticed it's to be diluted 1:100.. so statement withdrawn!!
