In our experience, and we see a lot of VAG cars, the ones that come in with the generic green coolant are the ones that have radiator and plastic coolant fitting leaks.Even worse is the heater core leaks which cost a fortune to repair.Use what VW/Audi tell you is right for your model and no added coolant leak/corrosion problems.

The thread starter so far hasn't mentioned what car the coolant will be intended for, but if it's for the Mk2 Golf GTI, then I can't imagine the owner's manual (if it's still there after all these years) would advise anything too specific.
But I would broadly agree with your advice, especially when it comes to anything remotely modern.
Not that it matters, but I swapped out the green and went bck to red lol.. after reading all ths stuff, just didnt wantto risk it.
Is it for the Mk3 Golf VR6?
Not that there is anything wrong with G12 coolants, but depending on how old it is, it may not require it (assuming that G12 coolant was even invented back then).
If you've still got it lying around somewhere, does the owner's manual recommend anything specific?
It was originally running G11, and then over time flushed out and ran G12 for many years. I only flushed the G12 out about 3 odd weeks ago and started running green again, more so to keep cost down while i was trying to find a leak somewhere since i since rectified (Would loose coolant slowly and need to be topped up every 4 days odd.) seeing as it was running G12, couldnt imagine there being an issue..You would think not anyway?? Yes, it is for a VR6. Well, mine is anyway. Not sure what car the person who originally posted is driving.

AFAICT, the higher spec (G12 onwards) coolant will only help - it will reduce the frequency of coolant flushing/replacement (arguably to zero) and will extend the life of your hoses and radiator.
The cost (as you noted) is the only possible downside and that should be paid back by the extended life of the G12 onwards coolants (assuming the leak is fixed).

Hi, yes, is now fixed. Turned out that there were 3 seperate issues. First issue was the thermostat housing O ring was gone so was leaking. Next issue turned out to be one of the small hoses leading from the oil cooler to the Crack pipe had a hairline split which I eventually picked up on. the last issue was that one of the o rings in the oil cooler was gone. It was a process over period of weeks to trace the last 2 as there were no visible signs of leaks. So....Thermostat housing, flanges, thermostat, all o orings, crack pipe, all hoses and the o rings to the oil cooler have beeb replaced and now have no leaks what so ever. The simple reason I went over to the green again was the running cost of constantly having to top up while i did my head in trying to source the leaks as there was no visible signs. From what I could tell, apart from being cheaper, the green stuff has all the rust inhibitors and what not so I went with it. I havent noticed any difference in terms of cooling or performace. Either way, have flushed back out and run with red again..
