Of course I don't want anyone to put something in their bus without being sure, but someone mentioned the 350Z
Nissan's lube chart says Nissan L248 for that:
In fact, it's the same coolant I had done about 1.5 years ago when I had it 'replaced' on my NISMO RS (the 5 yr service)

Still got a few litres of that, as he basically did a hose out/drain/refill which explains why the changes AFTER the first change are more frequent. They come in bigger 5L containers. I bought two, about £30 each, which I got in advance, and he used about 7L. I think the manual says it's 8L, but like I said he wouldn't have done all that distilled water flushing thing (it was a straight replacement of what was in their anyway), so I suppose the remaining 1L is the stuff still in the block etc, which gets 'mixed' with the newer stuff. I don't mind that as like I said, I'll have the next replacement again when it's due
And I know this might be rubbish, but it's green, and when I checked my Elgrand's coolant on that weird 'coolant stick' it is also green in those depressions on the foot of the stick. Given my bus came with full service history, and the owner had had a big service/coolant change about 2 years ago, maybe that's what's in mine, too.
