ive just been searching and maybe im using the wrong terms but i am curious as to the maintenance of the limited slip differential on my ae is. how often is the fluid or oil supposed to be changed? i remember seeing some additive for lsd's in the parts store i used to work but i never gave it any thought. im only at 23k but i wanted to know ahead of time. i know alot more people have the hlsd and wanted to see if nissan or anyone else gave them an idea about fluid change intervals or any other type of maintenance. thanks-haydn jr.
