Remind me not to buy that vehicle. From the RAVE Workshop Manual for the V8, Tdi and Mpi engines:

Use an ethylene glycol based anti-freeze (containing no methanol)
V8i, Tdi, Mpi with non-phosphate corrosion inhibitors suitable for use in aluminium engines to ensure
the protection of the cooling system against frost and corrosion in all seasons. Use one
part anti-freeze to one part water for protection down to -36°C (-33°F).
IMPORTANT: Coolant solution must not fall below proportions one part
anti-freeze to three parts water, i.e. minimum 25% anti-freeze in coolant otherwise
damage to engine is liable to occur. Or a maximum of 60%.

Straight water (even so-called "demineralised" water) is not good for anything with a mix of alloy and iron/steel components.
Google "electrolysis dissimilar metals" for a bit more info.

Well done Dave 😁😉

Flavour No 1. (Hummingbird Pheremone Flavour)

This you add to your existing oil to enhance performance, reduce fuel consumption, increase HP, re-rejuvenate worn parts and make you and your vehicle 'nearer to God than thee' (choose your own Nirvana(s) here)
For the conspiracy theorists they add the components removed by the Castro loving, war mongering political/military/industrial government types who want your engine to wear out prematurely so as to maximise their filthy capitalistic profit (wave flag here whilst holding hands and singing Kumbuyah) whilst totally ignoring the fact that it's the same oil companies selling the additives that you've supposedly been deprived of in the first place.
It helps to have some psuedo scientific names to throw about here along with a picture of a dolphin or two, smiling children (of different ethnecities) and an inference that our hummingbird pheremones are better than our competitors non organic hummingbird pheremones and that pollution will be lessened to leave you with a nice fuzzy feeling about how politically correct/socially responsible you are being

All of the above totally ignores the fact that the vehicle manufacturer and the oil companies probably have half a clue when it comes to specifying the correct oil for a vehicle and assuming the OP's D2a has run OK for the past 16 years on the manufacturer specified oil why mess with it ? In other words WOFTAM.

Flavour No.2. (Chocolate)

Aah ............. Chocolate, a good sensible choice for most ice cream devotees

Supplementary engine oil additives can be useful when trying to 'compensate' for the effects of wear and tear/ageing in an engine. A good example of this is the seal softeners sold by Wynns, Penrite etc and particularly Risoline that can 'restore' old hardened oil seals to effectively reverse a leaking rear main or timing cover seal. Very cost and time effective (when they work). They won't fix a damaged seal but can be 'magic' when used on an old hardened seal. Another example of a good effective additive is the example given by Sieraferry earlier, a tappet noise quietener. There are others out there that I am sure 'work as advertised'.

The difference here is that these 'chocolate flavoured' additives are used to mitigate or hide symptoms of engine ageing, usually in older, worn engines that may not be an economic proposition to repair normally or where a temporary solution is required. IMO when used correctly these additives are not a WOFTAM

Deano

at the end of the day Deano if a snake oil makes the end user happy and feel warm and fuzzy inside, is it harmful or still a con?

Unless they have changed their opinion, Du Pont, who invented the stuff, said it has no useful effect in oils but is unlikely to do any harm. Maybe a Google search can put the matter to rest.

Skinned Knuckles magazine had a series of articles over several months by a lubrication engineer. He had the same opinion as Du Pont. One interesting thing in his articles was that he says there are only four refineries in the USA making lubricating oils. The four make and package for all and sundry. Like the big battery factory in Carol Park. No difference in the batteries just the labels applied at the end of the line.

No worries Don.
Won't have to remind .. it'll never be for sale anyhow.

water for now is just the cleaning phase.
I've had coolant(concentrate) for a few months now just sitting in the shed, still waiting for the opportunity to use it.

I'm not going to add coolant until I know the system has been cleaned out thoroughly.

BTW, the CEM coolant flush/additive does have corrosion protection/inhibiting attributes!

In sixty years of playing with motor vehicles the only oil additive I ever found to be worth a knob of goatpoo was the original Wynn's Charge which hit the market in the 1960's. I had a used car yard for a while then and Charge was the answer to a bomb dealers dream. Bung in a can or two and old Smoky Joes stopped using oil and fuming for a couple of thousand miles or at least until well after sale. We used it by the carton putting at least one can in every car. Then some time later the formula must have been changed as it no longer had such a brilliant effect. Bugger!

We found mince meat in the gearbox and diff shut up noisy ones very effectively but don't be nearby when the meat and oil sludge was drained months later. 600W steam cylinder oil was also good. Fibrous wheel bearing grease in worn suspensions and steering joints worked for long enough to sell the pile of pus.

A man after my own heart!
I found the same thing with Bardhal Number 2 - worked great for smokey donks, but they must've changed as well. Did banana skins in an old Dodge gearbox once, but never heard of the meat trick! Guess I'm not too old to learn new tricks, after all.
