OK first of all i know people is gonna hate me because im about to say this.
Royal Purple is not as good as what people says or advertisements says about it.
So for my n16 i notice that the oil thins out at about 8000km and starts to burns.
For my s13 i also notice that the oil thins out at around 5000km and again starts to burns.(recently switched to dino oil )
Its an okay oil but i find it thins down too quick. IF someone needs to use royal purple they would need to change it often like regular oil.
But this is just me, from what i heard RP works well for others
