Just hit 1k miles & wanna get the break-in oil & filter out. Not sure how I feel about running 0W-20 as per what the manual states. I've researched previous Nissan/Infinity manuals & this Armada has the same motor & drivetrain as the 2011-2013 Infinity QX56 & 2014-2017 QX80 (Infinity changed the name, same vehicle). All are the same since 2011 based on the Global Nissan Patrol. All the previous manuals from 2011-2015 recommend 5W-30. The 2016 manual states using 0W20. What gives? Is this just for better gas mileage readings? Wouldn't the 5W30 protect better?
