2010 370Z Engine Lubricant etc...

munz

it's only driven 5800km, i just serviced it on thursday, added the nulon friday and realized it was a very bad idea when i saw the responses here. i figured i'd take it back to nissan as opposed to any mechanic (midas/pep boys/etc). i know an oil change is simple and straightforward, so maybe the sooner the better, but i'd have to call on Monday to find out.

i spent money on the stupid nulon to begin with, but if necessary i'd prefer to spend the money and fix the problem as best i can

also what petrol should i be using? premium 95, premium 98? i figured 98 is a cleaner burning fuel, but i was dead wrong about the nulon so thought i'd check this too.

and yes chrisw, new here and very concerned so i thought i'd make this thread to get some input as i'm new to all this, everyone's comments are much much appreciated, thank you.
