+1 Used Prestone AMM EL last time on my 2.5L Altima. Today I used Peak Long Life on same vehicle, I've had no issues. Especially when all Nissan spec says "green". Peak LL or Prestone easy to find, and the price is right.
Nissan says system should be maintained every 2 years or 30k, so that made this choice easy for me.
