Won't hurt a thing. My sister has an Altima that has had 0w20 to 10w40 and is over 100k. 0w20 was ran in summer between Louisiana and Mississippi in the summer. My Caravan was rated for 5w30 in 2012 then went to 5w20. Mine is an 18 with same engine design and I am running 0w20 without worries. Louisiana heat, city driving, idles alot and overloaded a few times. RPM has been 6500 on more than one occasion trying to get out of the way of idiots.
