That is another reason why I like dealing direct; they can tell you that every Nissan/Infinity build since 1996 uses a Ford style cap, etc. They have saved me both time and money over the years. They also make an excellen filling system for the Tiptronic trans as well.

I just got the "Euro" cap, works on my Mercedes and Porsche, plus fits my dad's '91 964 and my mom's '10 VW Golf. ;)
