mentman Posted February 4, 2011 Share Posted February 4, 2011 When I got my car, I was told by the garage that if I were to put regular unleaded in it (95ron) would melt the engine as in japan the fuel grade is around 100ron, but if I were forced to just to try and stay below 3500 rpm. Im cool with that, but is it safer to be using vpower level fuel @ 99ron or is 97ron premium ok? Alex Quote Link to comment Share on other sites More sharing options...

Geo Posted February 4, 2011 Share Posted February 4, 2011 99 RON will be the better option bud, but iv had to put 97 in mine before as i cudnt find a petrol station that did 99. id stay clear of 95 though. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted February 4, 2011 Share Posted February 4, 2011 Ive ran various twin turbo Soarers and Aristos on regular unleaded and none of them melted. True they run better on V power etc but theres no harm in running it on regular. Your garage are scaremongering Quote Link to comment Share on other sites More sharing options...
Josh Posted February 4, 2011 Share Posted February 4, 2011 AFAIK, UK Spec cars were mapped for 95ron but imports were mapped for 99/100ron. Quote Link to comment Share on other sites More sharing options...
downimpact Posted February 4, 2011 Share Posted February 4, 2011 97 will be fine, 99 wasn't even a readily available option some years ago in he UK. 95 on a jspec I would only use in an emergency. Quote Link to comment Share on other sites More sharing options...
safcdixon Posted February 4, 2011 Share Posted February 4, 2011 If you can get v power then that's the best option, I won't run mine on anything less just to be safe. Plus it smells nicer Quote Link to comment Share on other sites More sharing options...
jackso11 Posted February 4, 2011 Share Posted February 4, 2011 Load of rubbish. 95 will not damage the engine 97 will perform a bit better 99 will perform better still One thing to bear in mind though it 99 is only available from Tesco (I think), and not many of them sell it. Tesco petrol is budget and not as good as better brand Petrol. I have experienced 2 examples of this, one in an old Nova that was running very badly, always used Tesco petrol and was told to change to a better garage.....2 full tanks of Shell petrol later and all running issues were gone. Second was this month, I thought Tesco petrol would be better by now (nova was years ago) so have been running a new Mini Cooper S on Tesco Unleaded and been having running issues. Again, thought about changing to better petrol, 2 full tanks of Esso petrol later and once again all issues are gone. So, maybe a 95/97 from a branded garage would be better than 99 from Tesco anyway. Quote Link to comment Share on other sites More sharing options...

I've been using 95 for ages now, as Tesco 99 is far too expensive, and I've not really noticed any difference in performance, but economy isn't quite as good. IMO.

Jellybean Posted February 4, 2011 Share Posted February 4, 2011 Using 95 two years plus; I doubth anything here in Ireland is above 95 AFR are fine, boost is fine; I am running BPU Quote Link to comment Share on other sites More sharing options...
Guigsy Posted February 4, 2011 Share Posted February 4, 2011 I run 95 in the uk spec appart from occasionally. Last week I put 99 in from tesco for example. As the ecu had been reset and was running like a dog and the car sat for a while. So gave it a treat. The jap import mitsi legnum we also have I always use 99/97 but I'm sure it would run fine on 95. All on tesco and never had issues The melt engine thing is complete balls. You might get some det if your car is highly modified and not mapped for it (it's a single for example) but if you put 95 in a single mapped for 99 and cane the pants off it your a tool IMO Quote Link to comment Share on other sites More sharing options...
jackso11 Posted February 5, 2011 Share Posted February 5, 2011 I reckon if your car is highly modified you will have an AEM ECU or similar....so have it mapped to run on 95 petrol. Quote Link to comment Share on other sites More sharing options...
