I have always used Shell normal unleaded in all my cars. Have heard of bad things with cheapo petrol.Sent from my GT-I9305 using Tapatalk

I agree with you - but debating premium brand v. supermarket fuels here ends up in World War 3 - so don't go there!!!

I know what you mean. Its like the saying what came first the chicken or the egg!!

"Normal" petrol is 95 RON. Premium brand fuels and some supermarket fuels (certainly BP, Esso, Shell, Tesco) mostly offer 95 RON and 97 (or higher). Some budget brands such as Murco only offer 95 RON as far as I am aware. Not sure whether or not Sainsburys or Morrisons offer both.

FYI

Sainsburys has 95 and 97

Tesco has 95 and 99

Morrisons 95 only

Waitrose 95 and 98

Asda 95 only

Well so far on a tank of bog standard 95 I've done 200 miles and haven't used ½ tank as yet, it's a segment over the ½ tank mark on the gauge.

 

Now I don't think that's bad at all for a 2,0 petrol with DSG, and it should see me for another 10 days yet.

So I'm confused. The filler cap on my vRS says 95ron. Are we saying the default fuel should be 97/98?

You have beaten me to it when it comes to asking that question. 

From page 192 owners manual

On vehicles using prescribed unleaded petrol of min. 95 RON, the use of petrol with a higher octane number than 95 RON can increase the power and reduce fuel consumption.

Prescribed fuel – unleaded petrol 98/(95) RON

Use unleaded fuel with the octane rating 98 RON. Unleaded petrol 95 RON can also be used but results in a slight loss in performance.

 

Now I have the downloaded version of the drivers manual and on page 192, it has nothing to do with fuel, it has everything to do with securing a brats child seat and tethering it etc, etc, etc... No fuel stuff though.

Maybe the brats name was Ron

Maybe the brats name was Ron

As mentioned earlier in this thread,the filler cap indicates 95 oct.

So presumably the car isset up nd tuned for that fuel.

Hence that is what I've used from day1.

 

Perhaps this is why my consumption is less than most.-probably using higher octane rating.

Well I expect to have a good pay packet this month with bonus payments and several extra shifts so I might treat it to a tank full of higher octane stuff to see if it does make any marked difference to the engines smoothness, performance & economy.

Surely its only going to cost around £4 more a tank ?

Fairly sure that most TSi engines now are just rated for 95 RON use; i.e it will make the manufacturers quoted output figures there or thereabouts running regular unleaded.

suspect the regular use of a decent super fuel could provide a few extra horses and torques here and there given they all of course have sophisticated ECU electronics and knock cobtrol but the gains will be small.

I ran a Fabia vRS on 97-98 ron fuel religiously for the first several k miles of its life as it recommended 98 ron with 95 being completely safe with a possible reduction in torque output (the manuals words); it then went from being the wifes runaround to my company funded daily driver.....i was no longer able to buy super unleaded so was forced to use 95 ron.

......and I have to say I noticed little or no difference at all. Performance was indistinguishable, it ran smoothly still and was still just as bad on fuel as when running on super. It developed a high rev misfire but it was down to a software issue and not fuel quality; recieved an ECU update and never did it again.

The only quirk I have personally is that I endeavour not to buy supermarket fuel and always fill up at a branded station. There is very rarely much of a difference in price anyway and I dont know exactly why but I just trust petrol company run establishments to be less likely to ever contaminate the fuels etc.

So I'm confused. The filler cap on my vRS says 95ron. Are we saying the default fuel should be 97/98?

It says minimum 95RON it's recommended to run on 97RON or above

From page 192 owners manual

On vehicles using prescribed unleaded petrol of min. 95 RON, the use of petrol with a higher octane number than 95 RON can increase the power and reduce fuel consumption.

Prescribed fuel – unleaded petrol 98/(95) RON

Use unleaded fuel with the octane rating 98 RON. Unleaded petrol 95 RON can also be used but results in a slight loss in performance.

So the engine is optimised for 97/98 RON. If I had a vRS then that is unquestionably what I would use.

It says minimum 95RON it's recommended to run on 97RON or above

Is that what it says on the filler or is this in writing from Skoda/VW?

 

Needs clarifying I would suggest,as it would appear from this thread that there is general confusion.

 

Hence the Thread Question.

Tsi gains maximum performance and economy from 97 RON and above is basically what my PDF and physical manual states.

Exactly, I'm not sure what the confusion is.

Manual clearly states this folks. Also did in two of my previous petrol motors a civic type r and a Mini Cooper s. I could also feel and hear the difference between the different grades of fuel

See above re mention in skoda owners manual re above

Thanks everybody for your valued contribution to my thread.

 

My action will be to try a couple of tanks of 97/98 to give me a feel for everyday performance in power and fuel economy driven in normal mode for the majority of time as now.

 

However, on examination of both Skoda Brochure  and VW Golf GTI brochure  for the 220PS ENGINE,  the comments are the same -"Use minimum of 95 RON."

 

SO NOT SURE, HAVING READ A FEW TECHNICAL JOURNALs,  if the justification of addition expenditure exists.

 

But prepared too try options.

 

Guess it may also depends on how long you plan to own the car.

 

Can't see that the Manufacture would recommend a minimum that would unduly damage the engine-as warranty life is 60000 miles

 

Cheers all.

Using 95 RON won't damage the engine, but as I mentioned earlier in this thread it won't be operating at either peak power or efficiency if it is tuned around 97 RON. Not sure if I understand why anyone would buy what is supposed to be a performance car and then not get the best out of it.

IF it is tuned to that level . Do you know that as a fact?

I did not say that I did, here is my post again highlighted for clarification - as I don't own a vRS I cannot claim to have read the manual but various replies above seem to indicate that in summary Skoda are saying that whilst the engine will run fine on 95 RON you won't get the best out of it.

What's your usual route? You seem to be getting quite excellent mpg from this engine. Which is not something I'm getting, hehe.

 

I've tried both 95, during the running in as I was taking it easy anyway. And now I'm on 98. To be honest, couldn't really tell any difference. The engine is so smooth anyway and so eager to pull at any speed that you'd be going highly illegal speeds before you notice any real differences. I'll be running 98 anyway since the fill-up cost difference to 95 is minimal (around 6.5 euros) where I live. When you consider how much the car cost in the first place, that's peanuts... 

Again I have noticed an improvement of 3 to 4mpg on the maxi dot whilst using BP superunleaded so this goes some way in justifying the added expense and shows to me the car runs better. As for tuned to a certain grade of fuel you have to understand how fuel injection works and afrs etc. The car is tuned to run better and more efficient on the higher grade fuels
