Hello to Everyone who reads this post.

 

With the introduction early next year of 10% Ethanol in Unleaded Petrol. I have read that larger Petrol stations will supply both E5 and E10 unleaded juice and that 98 Ron (Super unleaded will stay at E5). It goes without saying that E10 will come to the fore though.

 

 I have read that a number of VW/Skoda/Seat cars will not be compatible with this fuel. Currently I am lead to believe that my BWA 2006 engined vRS will NOT comply.

 

I assume that either I get rid of the car or put it in a museum (ha ha) or run it on E5 98 Super unleaded. Unless anyone knows of another solution.

 

Thanks for any interest and comments in advance.

Hi John you are correct you either use Super Unleaded which will remain E5 or risk damaging rubber components with the cheaper E10. EU legislation forced manufacturers to make their vehicles capable of running on E10 since 2011 which some European countries have been using for several years already.

Thanks shyVRS245 for your information. I was wondering which components are affected in the fuel supply line and if there might be an upgrade path as there are a lot of these engines in use today.

Any source to show E10 will damage the rubber in a BWA engine or it's fuel system?

 

As far as I can tell, the VW SSP's suggest it's absolutely fine:

- http://www.volkspage.net/technik/ssp/ssp/SSP_334_d1.pdf

- http://www.volkspage.net/technik/ssp/ssp/SSP_337.pdf

 

Both documents pre-date the OP's car/engine and the BWA is newer than the AXX engine mentioned.

 

 

There is also no mention of the BWA on VW's list of engines that don't support E10: https://www.volkswagen.de/idhub/content/dam/onehub_pkw/importers/de/besitzer-und-nutzer/hilfe-und-dialogcenter/faq/e10_vw_zeichen.pdf

 

The only caveat is I think some earlier Octavia's specified RON 98 only so using any fuel with a lower RON, regardless of it being E5 or E10 wouldn't be recommenced. Check inside your fuel cap to see if you can use RON 95.

The Super Unleaded is not 98 Ron in the UK, so duff gen there.

Esso, Gulf, BP, Sainsbury, Costco are 97 Ron and just Tesco Momentum 99 and Shell V-Power Nitro + are 99 ron.

The ACEA compatibility list also suggests there will be no issue: https://www.acea.be/uploads/publications/ACEA_E10_compatibility.pdf

Škoda:

E10 petrol is cleared for use in all following Škoda vehicles with petrol engines with the following exception:

• Felicia 1.3 litre OHV (40kw and 50kW) engines used in Felicia models in the production years 1994 to 2001 and in car models before. A retrofit option exists for these engines to make them compatible with the use of E10 petrol – owners are advised to consult their dealer

 

Saying that, the wording should probably be:

E10 petrol is cleared for use in the following Škoda vehicles with petrol engines:

E10 petrol is not suitable for use in Škoda models with petrol engines whose owner's manuals specify the use of 98 octane petrol only.

E10 petrol is not suitable for use in Škoda models with petrol engines preceding those listed above (Forman, Favorit etc.).

Well I've been using Super Unleaded since 2003 so I'm biased. Mk1 Octavia Vrs 1.8T with 230bhp. It's his car he can put whatever he wants into it and petrols benefit from better fuel (higher octane) more than diesels.

My vRS Fuel cap allows 95 Unleaded to be used as an alternative to 98 Ron.

 

From the answers above it looks like the BWA engine and fuel line components are covered.

 

Thank you all for your informative replies.

Does it say you can continually run 95 Ron fuel in the cap? I’ll check my 06 BWA as I thought it said only to be used if 98 isn’t available or words to that effect? I’ve a few petrol turbo cars so it could be any one of them tbh 🤣🤣
 

ours is always run on premium, ideally yours should be too, well you certainly won’t be getting the same performance from 95 Ron fuel, you may find the difference in mpg will balance out some of the extra cost too.

While not having a Vrs, I can certainly vouch that there is a MPG gain in using 99Momentum in my 1.4 - I calculate it at around 2-4 MPG on mostly short, commuter trips.

@Vrsburnzy

Diesel is Diesel or Premium Diesel.  Unleaded or Super Unleaded is the term for petrol. 

Some might call Some petrol's Premium which is a bit of a mix up,

is that supposed to mean the Branded Super Unleaded rather than Super Market  Filling station Super Unleaded ?

(The price can be a Premium for Shell / BP Super Unleaded without the Super Unleaded being Superior to cheaper Super Unleaded available.)

 

Even in 2004 cars in the EU / UK / Europe had to be able to run on 95 ron even if the manufacturer might recommend 98 ron as they did with Euro 5 2010 - 2014 Mk2 Fabia vRS 1.4 TSI 132 kw Twinchargers which has 98 on the Filler flap and (95) as the Min.

It seems you are not quite correct, here’s is a thread which you was also part of stating that premium is 95 Ron fuel and super is 98 Ron as you’ve said, the Internet seems to agree on these terms too.

But I will take note of my mistake, although in this instance I’m sure everyone got the idea of what I meant.

 

Being able to run on a fuel and running optimally on it are two different things, hence why they state to use 98 Ron but admit it will still work on 95 Ron, on a performance petrol turbo engine the ecu will just be adapting and pulling timing for the lower Ron fuel, it’ll do it on a N/A engine but the results won’t be as significant.

@Vrsburnzy

VW Group have never recognised that no UK Retailers sell 98 Ron Super Unleaded anymore.

You get 97 ron Minimum or 99 ron Minimum, and that has been the way since BP stopped doing 98, and Shell changed to 99 from the 98 ron.

ESSO, Gulf, Texaco, BP, Sainsbury, Costco are 97 ron.   Costco was 99 ron a while back.

 

People can use what ever words or terms they like and journalists often do.  Things get lost in translation.

Go and try to find a petrol pump in the UK that has 'Premium' on it that is selling Super Unleaded.

what does the first part of your response have to do with the price of fish? 🤣🤣🤣

 

also your wiki link has just firmed up my argument regardingn 95 Ron being referred to as premium, it’s called premium in many cases in the “regional variations” section 🤣

 

I suppose its does say in the U.K. section that 95 Ron is classed as regular, but you never stipulated that only certain countries like the U.K. call it regular unleaded, I think you need to be a bit clearer with your argument.

The first part is to do with this.  The 98 ron bit.

The same advice or recommendation on a UK site now and for the past decade.

http://volkswagen.co.uk/need-help/need-help-faqs/owners/Fuel

Skoda, Audi, Seat never bothered to give the same advice for vRS's, Cupra's or Audi TFSI's with the same engines / software.

They could have though. 

They do mention Higher Octane's in owners manuals.

@Roottootemblowinootsoot

 

it pains me to post this photo, but here is the gumph in the owner manual. Stating output is reduced from the book figures on 95 Ron fuel.

 

it states it for a couple of engines lik the 1.8tsi for example.

 

That's good.  It is why i mentioned Owners Manuals and why i read them cover to cover.

It is why many of us use higher octane fuel, and get to know who sells what and what the minimum rating is.
