Yeah but how do you think we find it? We arent experts we all search to find stuff. If every person on here posted up a new thread for every question the place would be, and is, littered with duplicate threads. This is what causes the massive searches as now when somebody searches for similar this thread will now pop up and they will have to trawl through this thread also to find out theres no relevant info.
The general consensus is that when nissan put a badge on the fuel tank saying minimum ron= ** they have done this for a reason. The normal fuel causes knock issues and causes the engine to run poorly. If it was ok to use nissan would have said use it... but they don't and they also don't get commission from fuel companies for it also
