This Xterra is my wifes daily driver. Doesn't see much short tripping but it does see a good bit of stop and go. 35 miles round trip every day and weekend trips. I usually stretch my OCI a little further but with nothing to do for the COVID scare and a big oil stash staring me in the face, I got antsy. This is the 3rd OCI its seen under our ownership. Used a FRAM XG7317 for this OCI. Added maybe half a quart of the same oil at 3,750. Switched to PP 10w30 and a carquest filter when I changed it. Very happy with performance and MPG out of this rig. I am experiencing some top end chatter intermittently. Not the typical start up chatter but sometimes when I'm cruising through traffic at a low speed or climbing a hill offroad around 1000-1200rpm, I can hear one rocker or lifter specifically and its loud until i tap the gas and speed up. Its not very frequent but I'm monitoring it. Fairly new to the forum. This is the first UOA I've ever had done. I've been lurking here a while but I only kind of know what I'm looking at. Any advice, suggestions and comments are greatly appreciated.
