Not another oil/filter thread...

[nhbpcivicsi]

Well hello there everyone first off i wanna say that i do realize that this topic has been discussed multiple times but i would like to get an updated discussion around this topic. First of all, i've had the Z nismo for about a month now and its time for an oil change, which brand oil/filter do you guys recommend? i figured i would buy my own oil and filter but what im concerned about is if i do so, and if somehow it ends up causing a problem to the car, will the dealership void the warranty and claim that they are not supposed to fix anything related since i used a different oil/filter?
Again im sorry because this is a repeated topic any input would be appreciated
