That is why I am staying with my Mk1 vRS What mpg are you getting out of your Mk2 please?

30ish average, 44 at 70mph motorway run.

Sorry Stu, V Power was £1.359 a litre in Southampton this morning.

Damn you.

There is a lot of conflicting information on this topic.

I have to reply to Cech Customer Services with my VIN number for a difinitive answer for the forum.

I have personally had verbal confirmation that 98+ is to be used for the vRS and am happy with this advice, but there are a number of people who do not believe this.

As soon as I have my latest answer, I will post again.

Hi Guys,

I have just received a 'definitive' answer in an official looking pdf file from Skoda Cech Customer Services; quite clearly wrong, but have replied pointing this out.

"Fuel RON (minimum) 98/95 → Remark

4)

Also unleaded petrol 95 RON may be used on engines with prescribed unleaded petrol 91 RON although

engine power output will be slightly reduced.

5)

Also unleaded petrol 98 RON may be used on engines with prescribed unleaded petrol 95 RON

although engine power output will be slightly reduced.

6)

Also unleaded petrol 91 RON may be used on engines with prescribed unleaded petrol 87 RON although

engine power output will be slightly reduced".

So I suspect that this is a language problem and await their latest reply.

Regards

Tony

Dear all,

I now have a reply from Czech Customer Services, as follows:

"Dear Mr. Fendall,

You have purchased a vehicle with the engine 1,4 l/134 kW. Therefore, I assume that you want to fully apply all its features, which will be the case only if you tank the fuel RON98. If you use the approved alternative fuel RON95, the performance parameters of the engine decrease and the fuel consumption increases. The engine will not be damaged. This could only happen, if you use a fuel with a lower octane number than RON 98/95.

Kind regards,

I hope you find this useful.

Think this buries this topic now, was as I thought anyway. Well done for getting Skoda CZ to end the debate Tony, was something that needed answering definitively!

PETROL?

So what am I supposed to do with all this venom and the snakes I've been milking whilst waiting for my VRS to be delivered?

Hope you didn't buy crossbows too as spare wiper blades.

so the official skoda auto take is 95ron is fine but you get less performance and worse economy. Why buy the vRS.....

Shell V-Power was 140.9 here when I filled up on Sunday.

its 140.9 here for shell fuel save diesel :wonder:

Hi Si,

Not to dig mate but lets face it if you put 95 RON in one of these you'll probably lose a few horses and a smidge of low end torque with probably a very mild effect on fuel economy. It will still throw out 170ish hp and will still be very quick, much MUCH faster than the 105ps TSi. That's why you'd still buy a vRS.

I am totally with everyone here that the car will obviously run best on 97/98 RON fuel and for the sake of a couple of quid and a few more miles you may as well but using 95 RON fuel shouldnt be a reason not to buy one of these.

Used 98/97 for my first 3 tanks. Last two fill-ups switched to 95. No loss of economy as far as I can tell. Have noticed a very tiny loss of power, although this may well be psychological effect as I know there is 95 in the tank .

Later this week will be switching back to 98 to see if I can feel any power gain...

Does anyone on here use Jet's super unleaded as it is quite cheap where i live (about 135.9p)?

ive just averaged 27mpg over my first tank of 265 miles using Vpower. Wouldnt like to see the drop on 95ron fuel there are alot of short journeys though, and i dont drive like a granny

Quite agree.... whichever fuel you decide to run it on it still will be a rapid car compared to the rest of the range. If it is the same as the 2.0T FSi engine it would be a false economy running on 95 RON but if you did all the time you probably never notice..... unless you filled up with super

I think i'll run mine on Super, got a Shell card so can rack up some points!

If they say it runs better then why run it on anything else for the sake of £2 a tank?

I for one will only fill up twice a month tops so makes it £50 tops more a year to run on v-power.

if you get a further 2 mpg from using better fuel that starts to cancel out the extra cost anyway.

I think the point is, the best grade of readily available fuel in the UK is 99ron. but there are many other garages who do 98 ron or 97 ron fuel, so theres plenty of higher grade fuel options available before you slump to 95ron.

Agreed, 98 ron Shell v-power @ 1.35 ish iirc near me - fuel save diesel is same price...

I don't follow the extra mpg argument. As far as I understand, the higher RON allows earlier ignition timing bringing higher power at full throttle and/or the top end of the rev range. Saving on mpg would only occur if you always run your car this way.

from personal experience on my last car between 97 ron and 99 ron there was a solid 3mpg difference. Lower octane fuel detonates earlier and thus is less efficient. the higher octane resists detonation until the last moment meaning less fuel is required as there is more calorific value in it.

My internal combution theory is sketchy at best.

But if the ignition spark is closer to Top Dead Center at the point of spark surely due to the higher compression the power/torque bonus would apply to the entire rev band wouldn't it?

Sorry, my mistake. The higher octane stops pinking, which is pre-ignition of the fuel. But the point is that timing can be adjusted for higher compression giving higher power at the top end.

Apologies as above. But, as you may know from experience, you get pinking under full throttle where compression is higher. At lower throttle, where the compression is not high, no advantage can be taken of the extra octane.

Anyone been using 95 ron with no ill effect?

Just curious.

This has received a lot of thread mentions on here. I think the general consensus is:

95 RON - Will run on 95 (regular) Unleaded, reduced power output with possibility of long term damage if used extensively.

98 RON and above - Recommended. Will produce full power output, will run properly too. Common 98RON fuels are Shell V-Power (which is actually 99), BP Ultimate (not very welcomed by most people) amongst others.

Definitely recommend running a VRS on V-Power.

Don't forget Tesco's Momentum at 99RON; it's brilliant in my vRS.

Tony

I was using BP Ultimate in my vRS from new, used Shell V-Power last week and I seem to be recording better MPG so am going to stick with that.

I wouldn't use 95RON, it's recommended you use a better grade of fuel plus you pay a lot for the car, you don't want to skimp on the fuel.

I feed mine Tesco Momentum 99 only.

Having looked back over my fuelly entries I have concluded that my 1.2 TSI gives the best economy on Momentum 99. As I seldom use the engine at anything approaching full power I don't feel much difference in performance, pick up or smoothness between premium fuels. It doesn't seem too happy on supermarket 95 however but does run well on fuelsave. As this is vRS thread my twopennorth is that any forced charge engine with engine management that alters ignition timing to it's optimum is going to benefit from a higher octane fuel, especially a twin charged engine. As any car is mainly driven on part throttle on our congested roads the main benefit from higher octane fuel, apart from being a premium fuel with a superior detergents additive pack, is going to be improved economy. As you are making more power due to optimised ignition timing for any given throttle opening you can give it less pedal to achieve the same performance.
