I've had zero issues using green prestone for the past 100k on my 16v. Just change it every 2-3 years. Car never has any white build-up or any build-up in the hoses, so there's no real reason to not use it. Ph level stays neutral. Engine even has the original water pump at 180k :laugh:
Pros: zero issues, ph neutral
Mileage: 100000 km
I bought a 3/8ths 8 inch long copper tube, 4 screw tightening tube clamps and Prestone Antifreeze...I jammed 3 inches of that beast of a tube in one end and 3 inches into the other and put two clamps on each side to hold that baby in. There were flares on each end so I know the thing can't slip out at either end. It was a perfect fit. I then dumped that Prestone Antifreeze into the car and went for a test drive. NO LEAKS!
Pros: no leaks, perfect fit
Vehicle:
Volkswagen
I've used G12 and Prestone in one of my Corrados. No noticeable difference in performance or running temps. I did 100% complete system flush when changing over. I like the Prestone for availability.
Pros: no performance difference
Vehicle:
Volkswagen Corrado
You can regualr coolant as long as COMPLETELY flush out the system. I ran Prestone in my Jetta with regular flushes for 3 years with no problems...an no pitting of my cyl. head
Pros: no problems, no pitting

I think you should be fine. If it was the Prestone that you can add to all makes and models, that coolant is compatible with a wide variety of coolants. I have mixed that stuff with Dexcool and green stuff with no issues.
Pros: compatible with wide variety
Cons: mixed with Dexcool, green stuff
I've been using prestone in my 2.0 for 5 years with no problem. The heater will make you sweat and the cooling system works flawlessly.
Pros: cooling system works flawlessly
Cons: no problem for 5 years
Vehicle:
BMW
In a pinch I added Prestone Universal green to my VW coolant, next day the expansion tank had a nasty looking brown mixture in it that freaked me out, my desire to put inexpensive universal fluid to top off my B6 ended up costing me over $150 for VW to drain, flush with cleaner and refill with G12+.
Cons: nasty looking brown mixture
