For more on marking an answer as the "Best Answer", please visit our FAQ.Yes, you would, but the difference is slight. The Premium burns better, and you would therefore see a slightly improved performance, and (subject to you driving the same as you do on standard) improved fuel consumtion cos the engine has to burn less to do the same work. Whether the difference is worth the extra couple of pence a litre I can't tell you, but it's interesting that most manufacturers advertised fuel consumption and performance figures are based on using the higher octance fuel (i.e premium/optimax etc.), although mention of that is generally reserved for the small print in the brochure.
My S2000 has to run on Shell Optimax only. Something to do with the RON factor which is the degree the fuel with burn I assume (Mr Impet Sir may tell you what it really means)
I believe a more standard 1.6 (without being condescending) would run the same on any kind of unleaded.
The few times I have been unable to find a Shell garage and have opted for other Premium Fuels I have noted no difference whatsoever. Alas I believe damage can be caused if used too regularly.
Any fuel injected engine will have a knock sensor which will monitor the detonation of the fuel and adjust ignition timing accordingly. If you change the type of fuel, i.e. 95RON to 98RON it will automatically compensate for it and inform the Engine Management System which will make the necessary adjustments (one part of the engine mapping system).
As Beena mentioned, car manufacturers will use the higher refined fuel (burns easier/more efficiently) since it will demonstrate the cars performance better (0-60mph etc). However, when on economy runs there will be hardly any noticeable difference in fuel consumption.
If anyone is interested, petrol when it leaves the refinery its all very similar stuff, ie, with the same calorific value.(A lt of petrol contains about 7.5 million calories, compared to say, a lt of sweet orange juice, that contains about 500). What determines the amount of power that an engine can literally squeeze out of the fuel is defined as its "octane rating." This in indication of its propensity to be compressed without exploding. So, a fuels octane rating is an indication of the compression ratio at which it will damage an engine, and is determined like this:- a datum fuel, iso-octane, is fed into a small, single cylinder test engine on which the compression ratio can be varied. The point at which the compression ratio causes the fuel to detonate is said to be 100, and any fuel that detonates at that CR is said to be 100 octane fuel. The octane is then diluted with another fuel, n-heptane, and the CR at which this mixture detonates is equated to an octane raiting. A petrol that detonates as a 95% octane/ 5% heptane mix is a 95octane fuel. I fact there are two different test methods, using different engine speeds and ignition timings, hence we have the Motor Octane Number (MON) and the Research Octane Number (RON) ratings. Fuels tend to score higher under the RON test, so that is the one usually quoted. It is usefull to understand that a higher octane fuel will NOT without modifing the engine, produce more power. As engines have become better designed, in terms of combustion chambers and fuel delivery systems, detonation limits have been pushed back, allowing higher CRs with lower octane fuels. Octane ratings of over 100% have been achieved for certain competition engines by the addition of lead, although lead is now of course, thankfully, banned.
