Many of the early build Pathfinders, Xterra, and Frontier pick up trucks with the VQ40DE V6 engines were listed in the owners manual to run other oil weights other then 5w30. The early manuals listed I believe up to 10w40 as an option. Any of you here run 10w40 or 0w40 synthetic in your VQ40DE?
Personally I believe Nissan only recommends 5w30 in the later years like my 2012 for meeting fuel economy regs?
