I ran my 2001 on pink OAT for a couple of years, until I noticed that the SV650 that I put it in at the same time, had developed a drip from the waterpump seal.
Early Japanese engines were not designed for OAT (OAT eats brass and some seal materials), so I swapped back to blue.
I would put Prestone in now, as I am taken in by Prestone's hype that it "mixes with any type" and is "compatible with all engines"
Japanese cars use a green antifreeze that no-one seems to agree on what is in it.
