Yes, you could be right about the fuel quality, but it's probably not that. I think your mpg may be a bit low depending on what sort of motoring your are doing. But then again, it might be ok if you are predominantly in town. Your engine may be a bit tight, ecu learning still etc. If it doesn't improve check with your dealer to see if any upgrades for the ecu have come in recently. If not it may be worth getting it checked at the dealer.

Took a quick check at my two gas-stations where I live and... they have only 95 RON and diesel.. :(

So I guess I will get a engine that dont run nice at all!! THANK U SO MUCH SKODA!

THANK U SO MUCH SKODA!

A little unfair as the TSI engine actually comes from the VAG group which includes VW, Audi and Seat as well as Skoda.

I also think the whole fuel thing has been blown out of proportion as the quality of even 95 RON fuel can vary wildly between different brands and garages. There are also a number of reasons why the engine runs 'rough' and not simply due to the fuel type.

Just because you're not putting uber-expensive Shell V Power fuel in your car doesn't necessarily mean that it'll run poorly. Having said that I would stick to brands such as Shell or BP rather than using the supermarkets as a general rule of thumb means the quality will be better although not guaranteed.

I havent got my car yet.. (week 15).. but as I have read in this forum and what skoda write in the new user-manual where they now say use 98 RON it says all..

Just hope they fix this issue with a new ecu-map before I get my car.. but I dont think they will do :(

xcyber, don't get sucked in and panicked by the people on forums who are very clearly, sometimes, not well informed about this type of issue. My contacts in the trade, the technicians who look after these engines tell me there really doesn't seem to be a serious problem with fuelling of any kind relating to the TSI engines. They are sweet! Some issues mooted on this site are in my opinion not fuel related. Some people have experienced symptoms that may be octane related but it's difficult for anyone to know without a proper diagnostic being done. If you examine the posts on this thread and one or two other threads, just a few owners are saying they have experienced this or that and the fuel they use does this or that and a few ideas have been bantered around, including by me. No one is saying there are big problems or that anything won't get fixed, if it needs fixing. My guess is it probably doesn't need fixing, the cars will look after themselves once they have more mileage on the clocks and everything beds in ok. It's the same for all cars and manufacturers, and actually always has been. It's just we have the internet now and it's easier to see who's moaning about what! Don't forget, the overwhelming majority of Skoda and VW owners don't even know about this site. It tends to be enthusiasts and people with a beef who come onto forums. Chill man, it'll be ok.

Ok.. I hope u have right :yes: Happy x-mas to everyone.. driving my 98-mod peugeot home for x-mas tomorrow..

I was just wondering reading through this thread, why the UK has such a poor standard choice in fuel stocked. A recent trip to Koln, and I was amazed to see Aral having 7 different grades of fuel available, 4 petrol, 2 diesel and LPG. I'm wondering if the home market knows something about the home products and how they drive and what people demand, especially using the performance of the vehicle on the Autobahn etc. I regularly recall seeing at least 5 grades of fuel in the 80s at a lot of UK stations, 2*, 3* 4* 5* selected by pushing in the buttons and diesel around the back by the truck stop! Perhaps we forget we have anti-knock sensors and electronics doing all the work of our own ears, remember pinking? and choosing the right fuel and model of car, low compression versions for lower fuel grades were available in a lot of models to run on cheaper fuel. I don't see anything too wrong with having 'best performance' on 98 and if your happy running 95 then so be. OK before I'm told to move on for driving diesel, I'll have to be remembering its 98 in my Matra or its not so powerful and it will pink, but will run ok on 95.

Having read another thread on the actual power that VAG engines and in particular TSI engines seem to kick out which is above that stated in the manual/ stats I wonder if the 105 bhp is measured when running on 95ron therefore there is no loss of performance from book but may be gains from running higher octane due to direct injection, turbo charger and friction savings. Have to say that as it runs in the engine gets smoother and smoother with no noticeable lag will pull in any gear from just above 1000rpm with no issues, trouble is it is very quiet until above 300rpm with a growl developing that is very easy to travel a lot faster than intended. Now have 2400 miles on the clock and the idle is now beautifully balanced at around 900rpm when warm and fuel economy seems to be improving on simialr runs even with the cold weather running heated seats ect. Most journeys the computer is showing an average of 48ish compared to about 43 a few weeks ago. So will have to see if this continues if so will be very happy with this engine

(page 4) that is changed from the manual..

Prescribed types of fuel - unleaded petrol RON 98/95

Use unleaded petrol 98 RON. You can also use unleaded RON 95. However some loss

of power is to be expected when doing so.

If unleaded RON 98 or RON 95 is not available, you can refuel with unleaded RON 91

in an emergency. After refuelling, continue driving at medium engine speeds and

minimum engine load. Driving at high engine speeds or heavy engine loads can lead

to serious engine damage! Refuel with petrol with the specified octane number as

often as possible.

Fuel with a lower octane number than RON 91 must not be used even in an emergency.

Otherwise you can cause serious engine damage!

---------

And.. from the manual page 158: https://mediaportal.skoda-auto.com/resource/documentation/manuals/en/Fabia/11-2010/Manual/A05_Fabia_OwnersManual.pdf

Prescribed fuel - unleaded petrol 95/91 RON

Use unleaded petrol 95 RON. You can also use unleaded petrol 91 RON, but this leads

to a slight loss in performance.

If, in case of necessity, the vehicle must be refuelled with petrol of a lower octane

number than the one prescribed, you must continue driving at medium engine speeds

and low engine load. Driving at high engine speeds or a high engine load can severely

damage the engine! Refuel as soon as possible with petrol of the prescribed octane

number.

Prescribed fuel - unleaded petrol min. 95 RON

Use unleaded petrol 95 RON.

In case of necessity, you can refuel with petrol 91 RON if petrol 95 RON is not available.

You must continue driving at medium engine speeds and minimum engine load.

Driving at high engine speeds or a high engine load can severely damage the engine!

Refuel as soon as possible with petrol of the prescribed octane number.

Even in case of necessity, you must not use petrol of a lower octane number than 91,

otherwise the engine can be severely damaged!

You can find further information on refuelling  page 159, “Refuelling”.

Unleaded petrol with higher octane number

You can make unlimited use of unleaded petrol which has a higher octane number

than the one prescribed.

On vehicles with prescribed unleaded petrol 95/91 RON, the use of petrol with a

higher octane number than 95 does not result in a noticeable power increase or a

lower fuel consumption.

On vehicles with prescribed unleaded petrol min. 95 RON, the use of petrol with a

higher octane number than 95 does not result in a power increase or a lower fuel

consumption.

Use 98 RON.. :|

Use 98 RON.. :|

Is this stuff worth a go http://www.millersoils.net/1_Millers_frame_AUTO_FUEL.htm

Probably more expensive than just using 98 fuel

Most of these additives are marketing nonsense but many do say Millers is the exception.

When they get round to confirming the diesel ecomax is safe for euro V with DPF I will give it a try.

The problem here is that gas-stations around me dont sell 98 ROM fuel.. only 95 and diesel.

Hence suggesting the additive.It raises the octane level so you can use 95............if it works of course

The same at my city. There is only 95 and 100 RON petrol and due to high price ~1.55 and 1.80 euros per liter each i only use 95 RON petrol. I created the threadfor bad idling at Roomster's corner.

Nowadays after five months of everyday use and 9.200 kilometers on clock my roomster still does not perform cold start from times to times but since 6.600 kilometers she never had rough idling or hick ups. Last time she didn't perform cold start was an hour ago but the engine was once more smooth at about 900 rpm and instant fuel consumption 0.9 to 0.8.

I can not say if there is power loss since i have never use 100 RON petrol. My average consumption is 6.6lt/100km. I managed 4.9 once at country road. Moving at a speed of 80 to 100 km/h the consumption is about 5.3 to 5.5, at highway at a speed of 120 - 130 km/h the consumption is from 6.3 to 6.7. In the city due to very short distance from home to work (about 2 Km) the consumption is from 8 to 10.2

My opinion is that there is a possibility to experience some rough engine idling but after some kilometers this phenomenon will be smoothed out and gradually will be disappeared.

I am sure enough that you will enjoy your new car as much as i enjoy mine every single day. Problems will always be there, we just try to find a solution through discussion and brain storming.

Hence suggesting the additive.It raises the octane level so you can use 95............if it works of course

I don't think this is a good practice in a brand new engine.

Just got confirmed that the guy in this video always use 95 RON without any problem -

"Yes, we are always using 95 octane petrol. I don't have a problem at all. Beautiful acceleration always I want! I have passat CC 1,8 TSI as well and I must say that fabia 1,2 have a best pressure to seat than passat ;-) I love it!"

That sound nice

Mine`s improving slwoly, I switched back to 95 RON and I`m only using either the local BP or Shell (its a bit further away so I use it less regularly). Oddly enough now its got a few more miles on it (getting on for 4K) it actually seems to be less aggressive with coming on and off boost and it seems to be slower to accelerate but acelerating for longer if that makes sense.

Economy still isnt brilliant though, but not sure how much of that is down to my driving style (and I can`t be that bad as I can get our Superb into the high 40s low 50s) and how much of it is down to the car still being a bit tight. I`d have prefered the 6-speed box that other TSI engined VAG cars seem to have (Yeti and Leon for example).

Hi Ross, yep...she's still very tight at that sort of mileage and the rings are still bedding in. You've got plenty more power and economy to come yet. Just wait, you'll see.
