It's getting really hard to find true green stuff, especially pre-diluted. I've used the all-in-wonder yellow stuff in other vehicles but would prefer to stay with old fashioned green in the G. What scares me away from yellow is that it's Dex compatible. I had a '99 Alero that ended up being part of a huge Dex related class action lawsuit due to the coolant eating 3.4L engine gaskets. I don't know how many properties the yellow stuff shares with orange Dex, but Dex really put a bad taste in my mouth. Green tastes much better Thoughts?

 

Green does taste better. Make your own 50/50 mixture with the OEM coolant. You'll pay a nice price but very rewarding...as far as making your own coolant goes

 

In case anyone searchs for "yellow coolant" and finds this thread, I wanted to followup. Menards was one of the few places I found that carried premixed green from Peak. I ended up purchasing that. Advance auto and autozone both had straight up green for about $10. Walmart only had yellow along with true orange Dex.

 

Interestingly, I just drained/flushed, and refilled my coolant for its 30k mile maintenance interval. Infiniti was very specific in stating that you have HAVE to use the green coolant - I did swing by Autozone and saw that Prestone sells a predilluted 'ANY Color' variant, but I did not purchase it. I was not able to find a Preston green version that wasn't GM specific, so I opted for the Nissan green coolant purchased from a Nissan dealership at around $29.

 

That better be some pretty amazing coolant for $29
