SimonKevNorris Posted February 7, 2017 Share Posted February 7, 2017 I'm wondering it anyone can help me. I'm currently working in Dublin and I brought my 350Z over with me from the UK just before last Xmas. I bought the car new just before Xmas in 2008 when they were being heavily discounted (I bought a GT pack coupe for £7.5 K off the list price). I'm having trouble sourcing anything other than 95 Octane fuel over here. I know the 350Z needs 98 RON fuel. I was in the UK last year and even there I was driving between Shell and Tesco service stations for 98 or 99 (Tesco) fuel. I still have over half a tank of Shell but I need to fill it up in a month or so (I'm in about 15 minute walk from my apartment to my desk). I know it would be possible to source fuel in NI but I'd probably use 1/2 or a 1/4 tank getting back (plus the toll road around Dublin). I've yet to try the local Tesco here but I'm fairly sure that they won't sell 99 octane fuel, Is an additive the answer? Thanks in advance.

G1en Posted February 7, 2017 Share Posted February 7, 2017 You could get a 20ltr jerry can or 3 and fill them up at same time as the zed so its not so much a waste of fuel as you will have a stock. Then when you get back to england you could sell them to get some money back or keep them in reserve for when the walking dead zombie apocalypse hits. From previous threads though. An additive is ok short term or running 95 ron is ok if you keep below 4/5k rpm ie normal driving Quote Link to comment Share on other sites More sharing options...
SimonKevNorris Posted February 7, 2017 Author Share Posted February 7, 2017 Thanks for that - my car was full when I came over here (suitcase in the passenger well and travel bag on the passenger seat) and the 'boot' was choker block (I'm glad I have a coupe). So, the only place for some jerry cans would be the roof in a roof box and I'm not even sure that would be possible to do. Quote Link to comment Share on other sites More sharing options...
StevoD Posted February 7, 2017 Share Posted February 7, 2017 Topaz do a 97 octane fuel i know there is a few around dublin but i have always stopped for diesel so never looked which ones have 97 sorry Quote Link to comment Share on other sites More sharing options...
KyleR Posted February 8, 2017 Share Posted February 8, 2017 Zero super in the ROI, your only option is to run 95 and take it easy, below 5k as mentioned. Use good quality proven octane boosters if you wish to ensure safe running. Like you mention, you can drive up here to NI, but thats not really practical. 1 Quote Link to comment Share on other sites More sharing options...
SimonKevNorris Posted February 8, 2017 Author Share Posted February 8, 2017 (edited) Topaz do a 97 octane fuel i know there is a few around dublin but i have always stopped for diesel so never looked which ones have 97 sorry Thanks for that. There is one Topaz down the road from me (I'm in Ballsbridge) in Merrion Rd which is near St Vincent's Hospital. I've been in there before as on Sunday they do the jet wash for you. I'm fairly sure that I checked before - but I will do so again. There is a larger one at Mt Merrion that I pass coming back into Dublin. Zero super in the ROI, your only option is to run 95 and take it easy, below 5k as mentioned. Use good quality proven octane boosters if you wish to ensure safe running. Like you mention, you can drive up here to NI, but thats not really practical. Thanks for that. I took my 350z up to Newry in December 2015 in order to get an MOT when I was in Dublin last. I did manage to get an MOT in Reading before I left the UK in mid December 2016 so I don't need to do that trip again until later in the year. I'll try the Topaz garages to see what they do - but I'll try and get an Octane Booster and drive carefully.

MikeyM Posted February 8, 2017 Share Posted February 8, 2017 I feel your pain with the lack of super unleaded..living here on Skye in the Highlands it's a 30 min trip each way for it.. so I'm cautious with the revs in general..not ideal in a 350z, 😣 Quote Link to comment Share on other sites More sharing options...
JetSet Posted February 8, 2017 Share Posted February 8, 2017 If you have an HR they can run on 95 RON, definitely not recommended long term, but if you keep the revs down to say 5k then all should be fine. If you have a late registered DE then.......just take it real easy Pete Quote Link to comment Share on other sites More sharing options...
Ekona Posted February 8, 2017 Share Posted February 8, 2017 Indeed, if it's a HR don't worry about it. Quote Link to comment Share on other sites More sharing options...
SimonKevNorris Posted February 8, 2017 Author Share Posted February 8, 2017 I presume an HR was the final version (engine wise) of the 350Z? I'm fairly sure that it's the version with the most HP (standard). Is the only way to find out to look at something under the hood/bonnet? Will it be on a plate or is there some other way to tell? http://i.imgur.com/6uzxZ5b.jpg Thanks again Quote Link to comment Share on other sites More sharing options...
Ekona Posted February 8, 2017 Share Posted February 8, 2017 Look under the bonnet, if you have two air intakes then it's an HR. Looking at the bonnet hump that's very likely, but not impossible to swap. Also, if your car revs to 7500 it's definitely an HR. Quote Link to comment Share on other sites More sharing options...
350zedd Posted February 8, 2017 Share Posted February 8, 2017 The HR engine is fitted with knock sensors which detect detonation and automatically alter the ignition timing. This reduces the risk of engine damage caused by knock, while running on low octane fuels. 3 Quote Link to comment Share on other sites More sharing options...

Looking at the bonnet hump that's very likely, but not impossible to swap. Also, if your car revs to 7500 it's definitely an HR. OK, I will look for that then. My car is currently in an underground car park with the front (where the car's front is) fairly low. I don't think I've ever revved the engine very high - it's still low mileage - just over 22K miles and most of that was done in the past 12 months. The HR engine is fitted with knock sensors which detect detonation and automatically alter the ignition timing. This reduces the risk of engine damage caused by knock, while running on low octane fuels. OK, thanks for that. I think I'll still be happier when I can get some decent fuel for her. Until then I'll look for some additive and not go crazy in her. Quote Link to comment Share on other sites More sharing options...
Ekona Posted February 8, 2017 Share Posted February 8, 2017 Erm, if you've never revved the car to the rev limiter then you really need to be doing that: Sitting at low rpms isn't a good thing for modern engines at all. They're designed to be used properly, so don't be afraid to bang the limiter every now and then. Quote Link to comment Share on other sites More sharing options...
GT Driver Posted February 10, 2017 Share Posted February 10, 2017 I live in Dublin. Unfortunately super-unleaded is not available here but in terms of quality of fuels I'd stick to the main brands such as Topaz, Esso or Maxol. With a preference for Maxol as they used to yield a slighter higher octane in their 95. I know about 6 or 7 people with Zs that have been ran exclusively on 95 RON over the course of their lifetime and they are still going strong - some with higher mileage such as mine at 87k. You will be hard pushed to find high octane in Northern Ireland also. Additive may be your best bet. Good luck. Quote Link to comment Share on other sites More sharing options...

KyleR Posted February 10, 2017 Share Posted February 10, 2017 I thought it was hard to get up there nowadays? Must have read it wrong! Shell pulled out a few years ago and took 99 with them, but 97 is still widely available 1 Quote Link to comment Share on other sites More sharing options...
