The 2nd gen rogue (15-20) is multi port and not GDI. There was an analysis on a Nissan forum rogue, who ran amsoil SS a full 25k and everything looked outstanding, next to no fuel dilution. The 3rd gen rogue which used a 2.5 in 21 and then moved to the rattle box 1.5 turbo is DI. My 21 and 24, while I don’t know all the specifics, uses both DI and port injection. There’s a member here with a 19 Altima (DI and port) who posted a UOA and it looked like a port injection for the most part. I suppose with UOA, you and I could run extended intervals but, I choose to stay around the manufacturers recommendation. Doing a spill and fill every 20k on the cvt is more of a necessity imo. My cvt operates like new and drains spotless everytime. If Nissan had half a brain they’d change the recommendation of trans service and not destroyed their reputation because of it.
