Farmer Brown Posted June 6, 2013 Share Posted June 6, 2013 (edited) I have a 54 plate 276BHP UK GT Zed. It has done 54,000 miles and i have owned it for about 6-7 years and done 30,000+ in it. Until i found these forums i tended to run it on standard 95 ron petrol, not through tightness but i just assumed as that it wasn't a turbo super unleaded wasn't such a big deal. :blush: However i have now seem posts going on about engine knock caused by 95 ron petrol damaging engines and it is super all the time for it now. Must say i have never noticed any knock now or before when i used 95ron and even when i do drive it hard i always tend to warm it up before a run and let it cool itself properly after. Car seemed to run ok on 95 ron just not as smooth as super and didnt have as much power. Car seems to be running fine now, has never needed any oil its whole life (i check it every week) water has always been fine and there has never been any sign of contamination of water and the oil pressure always seems to be ok. Car has been serviced by nissan once a year since new and all they have said about engine is that it is pretty good. So if everything seems alright is the engine alright or is there damage that i might not know about?? The car seems ok for power, 50-70 in 4th today just under 4 sec and in 3rd about 2.8ish and will comfortably go well up into 140-150+ territory (gave it a run to try this last weekend), i have put it on the limiter a few times but not for a while. On an old airstrip of course. Was thinking of taking it to the local rolling road (this weekend if poss) to see if it still had all its horses and thought if it did then it must be ok. It is running a scorpion exhaust and pipercross panel filter so anyone have any idea of what power it should do if all is well?

spursmaddave Posted June 6, 2013 Share Posted June 6, 2013 If you have run on 95 for a long tome it might be worth getting things checked out, not sure how expensive it woukd be though I would personally just run it on super now and try not to worry about it...

Did the great big sticker saying '98RON ONLY' by the fuel cap not give you a hint?! Regardless, I wouldn't fret over anything now, just stick with 98 from now on and whatever will be, will be. Nothing you can do about it either way, so no point in worrying 1 Quote Link to comment Share on other sites More sharing options...

Arran Posted June 6, 2013 Share Posted June 6, 2013 So when you come to sell it on here, it's been run on 95 for 30k miles should be alright (maybe) but yeah super from now on mate, 99 if possible I'd say. I keep all the petrol receipts for mine (v power or momentum) so it's all documented, did that with my last car and the new owner said he's never seen such an anal enthusiast I mean keeping 3 and a half years of petrol receipts just to prove to the new owner it's was run on 99 how many would do that? Was about 4inches thick (ooh eer) of receipts Quote Link to comment Share on other sites More sharing options...

The Bounty Bar Kid Posted June 6, 2013 Share Posted June 6, 2013 I was at Abbey today and Tony showed me a piston from a 350 (sorry don't remember the year) that had been run almost exclusively on 95 Ron unleaded fuel, please don't do it guys, it's going to hurt your engine AND your wallet eventually................... ~edited to make clear this was use of 95 Ron almost exclusively Quote Link to comment Share on other sites More sharing options...

The Bounty Bar Kid Posted June 6, 2013 Share Posted June 6, 2013 I just can't understand why people would think 95 Ron is OK when it clearly states 98 Ron only. Quote Link to comment Share on other sites More sharing options...
spursmaddave Posted June 6, 2013 Share Posted June 6, 2013 (edited) Yes and of course all of you guys laughing (who have Zeds) have had them since they came out of the factory and KNOW that they have been run exclusively on 98ron don't you?

NeilMH Posted June 7, 2013 Share Posted June 7, 2013 If it runs ok now I wouldn't worry about it ... just run on Super in future as planned. Quote Link to comment Share on other sites More sharing options...
ozwald Posted June 7, 2013 Share Posted June 7, 2013 On a related note, despite it stating 98RON on the fuel cap, and in the handbook, Nissan's official line is that it will run fine on 95RON, and I have that in writing from them. Although good luck getting a new engine from them if it's borked from running on 95.... Quote Link to comment Share on other sites More sharing options...
