Miles per full tank

160 city driving miles on a full tank? Is this good, standard or poor?
Sounds poor to me Alan - would expect more like 200 plus even in stop/start traffic.
When do you stop filling your tank - 1st click, 2nd click or when your Nike's get covered in 95RON? I go to the 2nd click myself.

Can you run a Noble on 95RON then?
Standard calibration is for 95RON fuel. However due to high charge air temps and inducted oil when on track/pressing on we recomend you run a good 97RON super unleaded or Optimax.

Just to be clear, and AFAIK, the factory recommends 95RON whether on OR off track so the above is a Faulkes only recommendation (although I also use Optimax just before, during and after a track day but have read reams of text supporting AND denying its usefulness!).
Happy to be corrected - factory?
) I spoke to Trevor (yellowshed) about this, and he confirmed that the ecu map is indeed set for 95ron. Although if you have spent £50k plus on a car it must be worth spending the extra pennies per litre for optimax, just to keep the engine nice and clean inside, i know this works, as was looking inside my engine the other week !!! and it looks like new in there. 
But running on 95 ron will not harm the engine.

Alex, as a man who likes to clean all parts of his Noble I am impressed with your attention to detail Nobleman!
ps - do you also remove your tyres to clean the wheel rims properly?
pps - just kidding as obviously you were in a workshop somewhere!
The map is set at 95RON, but can you be sure that the 95RON that you have will be to the same spec and quality as what they used when they created the map, and also that you won't be at high altitude.
Given it's a 60k car are you really interested in saving 4ppl?
Optimax also has many additional detergents that are good for the engine. Decoke's are a thing of the past since fuel injection came in, but if you look at a 30,000 mile normal car engine you'll still find quite "interesting" deposits.
So, you will almost certainly be fine with 95, but for peace of mind and to pamper your little baby, stick Optimax / Ultima / 97SUL in it would be my take.

All Noble models run on 95RON unleaded. Due to the way the engines are mapped, using anything higher will not improve performance (though neither will it harm the engine).
For the fuel gauge to move from full to empty in 160 miles of city driving is normal. It should reach to around 200 miles on a fastish run.
Bear in mind that when the gauge first shows empty, you're unlikely to refill it with more than 40litres, which leaves a decent reserve. However, due to the
way in which cars are likely to be driven, Noble always recommends that you replenish the tank well before it's empty.

95 Ron is fine and recommended by the factory, indeed 'tis what the cars are mapped on. HOWEVER having been on the wrong side of below par fuel 3 times resulting in 2 complete engine rebuilds on my rally car (in one year!) we eventually sussed that it was the fuel. The car was mapped on 95 and we purchased the fuel and ran it on 95 bought from the same service station - a reputable one at that. It was only by chance that we met a fellow competitor on an event who lived locally and filled at the same pump. He went to the expense of having fuel tested and it was found to be defective. So after rebuild #3 we remapped the car initially on the fuel that we had left in the tank. Suprise suprise it was detting its tits off at high rpm.
That was 5 years ago and since then we map for a lesser fuel (Optimax) than we use on event (99/100 RON) Never had a problem since.
OK so this was a rally car but since then I stick to this practice and use only use Optimax in high performance road cars. It won't give any performance advantages but it will protect against possible fuel issues, has more lubricant technology and costs nigh on fapp all extra ! I'll pay the few pennies extra and have peace of mind thanks!
IMO it doesn't matter what car you have there is no accounting for pants fuel from even well known fuel suppliers - manufacturers obviosuly have no control over this. Crap fuel is not really a problem for the majority of mass market cars though because manufacturers spend £ 00,000's on pretty much fail-safing their maps.

broad said:Of course most "modern" cars have knock sensors and so really don't give a dam about the quality.

My X5 says it will run from 86 to 98 RON quite happily!
