De carbonising

Featured Replies

Hi I was wondering 

 

Is it worth getting a turbo engine professionally decarbonised. If so when should one do it and how often. My car has just over 7000 km and still has approx 8 months to the next service. How much does it cost about.  I'm in Australia. 

@LuxoviaRS

  1. Probably not.
  2. See (1) above.
  3. 7_000 (seven thousand) km? That's not even properly run in yet!
  4. No idea about job time, or about Strine labour rates. Or indeed which engine you're asking about.

Not sure but would i be right in thinking you believe it should be done on "this date" every year?

Ok thanks I guess a bit too early for that.  Ok yes true it still needs to be run in. Ok I have an Octavia VRS it has the turbo petrol. Was just curious if I should be worried about carbon deposits at this stage.

I am not really sure to be honest i just want to avoid issues with the turbo engine I have and was thinking is this process a good way of getting rid of carbon build. Whether I need to do it every year I don't know,   I'm just asking. Thanks for your reply

I though it was an April Fools.

?

What carbon build up? 

What fuel are you using? 

 

You have a 5 year manufacturers warranty in Australia do you not?  Best not void it with the 'Professional decarbonising ' the engine.

Nope not April fools lol 😆

 

Seriously, I'm referring to carbon build up in intake valves in direct injection engines.  Also VAWg engines from what I read in the past somewhere can't recall where are prone to this issue.

 

I'm using the recommended which is 95 and some times I've used 98 RON. 

 

Actually I have 7 year warranty to be precise. 

I read such stuff as well.   

So now you have an Engine with VW 508 00 / 509 00, 0w 20 FS IV Oil with detergents and petrol with detergents and a Cat and a Gasoline Particulate Filter and a 7 year warranty.

 

I would service it to the schedule and run the car and fingers crossed that in 10 years the engine is as good as it is now.

'Keep it away from witch doctors'. 

 

If there are still issues outside of the US with carbon build up we will hopefully hear on here about that.    Then we can ask VW Group, WTF happened to Vorsprung Durch Technik.

ETA: Rooted posted whilst I was still typing but I've left my post as it was.

 

I almost posted last night if you were being serious (but had totally forgotten about the date).

 

Over here 97 and 99 octane fuels generally have a higher cleaning additive package in them which might help with regular or fairly regular use in addition to regular proper and timely servicing, of the whole car but engine in this case, engine air filter, spark plugs (good quality engine oil for generally).  And I'd suggest driving the VRS as it's designed to be driven when you can to get a good volume of clean (as possible) air and petrol in, through and out of the engine.

 

Depending on what's in the air where you drive changing the air filter more often than service spec might be advisable, unless VW has already taken that into account given you have a 7 year (!!) warranty,  The car manufacturers have too much power and influence in Europe and UK for us to get anything like that unless it's an Asian  car manufacturer then snobbery and protectionism puts those brands down to keep the likes of VW's prices up and their customers expectations down.

 

Modern sports style engines and transmission gearing are ridiculous given the legal speed limits, Google tells me 130km (81mph) or 110km (68mph) for Aus, in the 1960s 60-ish (or less)  horsepower cars would be doing that in the UK (they were of course a lot lighter than modern cars) so the only way you can exercise the modern sports style engines car is acceleration and gear selection which goes against fuel consumption of the cars (even when the manufactures aren't manipulating the figures they give).

Witch doctors lol nope don't plan on taking them there don't think they will be much help 🫤 but I know what you mean 😆.  Anyway I'll keep up the servicing with the 7 year warranty, though I don't think  l want to wait till 10 years and hope that the engine has been looked after 😅. No ill leave it to others to ask that rhetorical question of VW Group, I'll rather not have to find that out. Oh and 10 years i don't know if I want to go that far.

Hey thanks I really appreciate it. No I'm serious I don't understand why I would not be,  isn't prevention the best answer. Here in Aus we have 95 and 98 our e10 is not suitable for the vw engine, I was warned against it. I do want to take the car for drives at those speeds but hardly get the time as the car is used extensively in urban city driving in traffic most times for work. The average speed is 26 km. Unfortunately near my home all the highways are 80km and tolled which i refuse to pay. I have to go out of the city in the outer suburbs to get speeds like that. Yes varied driving is the best and exactly the economy suffers already I'm finding the fuel economy isn't the best but I'm hoping it will improve over time.  In terms of accelerating and choosing the appropriate gear selection I will try that out.

Again, you posted as I was typing the first bit of this post (my posts are often (one-finger) typed in stages whilst not multi-tasking) .

 

Prevention, well perhaps partial at least, is better than needing a cure, as I've put above try to have things as (reasonably) clean as possible to help keep things as (reasonably) clean as possible for as long as possible, this will also give you better performance which includes relative good fuel consumption.

 

(after seeing your post now).

Not sure why you have a VRS model but that's your business, I was going to put about V8s and fuel consumption but won't now given your concern with the Octavia's consumption. 😆

 

I'm with you on toll roads though I have used them, and been persuaded (told) to use them by my boss.  😉

 

Given the low speeds unless you need lugging power wouldn't a smaller more economical engine be better (don't you get the smaller and IMO better Japanese engines and cars there any more (or Chinese for the coal).

 

For the city the stop/start might be useful for fuel consumption and emissions and perhaps autobox and most of the other intrusive driver "aids",  get the car's computers programs working for you as they'll have you working for them, particularly if you upset them (by letting the battery get too low, even if the car starts and the lights seem bright enough and there are no warning messages or light yet) the heat much above 20c can be literally draining on the battery.

 

For economy and spirited/"fast" driving, wear and tear on the car's parts, components and systems it's a lot about the driver's driving technique and style (I say this as a not particularly good driver).  One of the best tuning aids for the car after or possibly before, full and proper servicing, maintenance and repair of the whole car is driver training and it can be transferred to other cars at no cost or loss.  That goes that goes against the macho minds over here too.  😆

 

I used to see that some in Aus ran their tyres at higher pressures than we do here and what is recommended in the Owner's Manuals, and I've no idea of how they interpreted when the tyres were "cold" but tyres pressures can have an influence on fuel consumption as well of course carrying unnecessary weight, make them walk, 😁 tools, junk, or unnecessary items on the car that increase drag, having lots of electrical items running.

 

Having done a lot of the economical driving and mostly urban city driving you then need to give the car blow-out runs (and a bit more for VRS types), particularly if it's diesel or petrol with GPF negating at least some of the fuel consumption driving.  I once done a 200+ mile (320+ km) drive with a 100 m section at 50mpg (5.65 l/100km) when testing engine and carbs set up and another section when my mate joined us at 25mpg (11.3 l/100km), first at well below legal motorway speed limit and second normal motorway speed, you can have it both ways but not at the same time.  🙂

whats different between your E10 and the rest of the worlds E10?

Almost sounds like a FUD type statement (although ther eis a grain of truth it would appear)

yes but its the ethanol that potentially causes problems with rubber seals and stuff and not the Octane rating so why is it ok to use ethanol in UK(and rest of Europe possibly world) Skodas (with the above single exception)  but not in Australian sold Skodas?

DO they use different components or is Australian Ethanol somehow different?

Volkswagen say 95 0r  98 Ron so they care about the Octane

Let me try that again:

Problem Statement: 
Fuel containing ethanol can turn corrosive if left in long-term storage, while ethanol's high solvency can affect seals and gaskets used in some fuel systems. Finally, combustion can be affected, with ethanol affecting cold start performance

Issue:
UK Govt Web site states all Skodas (except specific Felicias) can have Ethanol based fuels used in them
New South Wales checkers states that a 2023 Skoda Octavia (along with others) is not compatible with fuel containing ethanol

Question(s):
What's the difference between the seals & gaskets used in UK Skodas and Aussie Skodas?

Do VAG use different seal & gasket materials in different markets for some odd reason?

I think there are two different issues.

 

The seals are probably compatible with the percentage of Ethanol but "Volkswagen" set the cars up for 95% Ron and in Aus their fuel does not meet that.

 

 

 

They sell the vehicles into Australia knowing exactly what the fuels are.

As for Mon / Ron best people get to understand that. 

 

In the UK the E10 might have up to 10% bio-ethanol and might have much less, as the E5 might have up to 5% and might have 0%. 

Regional Distribution in the UK, storage etc.  producers and wholesellers. location location location.

PS

Skoda Citigo in South America were available with 1.0 TSI engines and bigger fuel tanks and ran on E85. 

whilst you're probably correct  in that Aussie fuel is lower rated ie faced with this choice then you would need to use the 98RON to get above 95RON

E10 sign

The NSW Checker states that VAG do not recommend the use of ethanol based fuels hence the question "why cant you use ethanol based fel in an Oz Skoda if it was at the correct minimum octane rating?"

Supplemental question, ijust how much of a difference is there between E10 94RON and E10 95RON ? Would it really cause any issues?

Jon over at Auto Shennanigans did a basic comparison and found E10 at his local fuel stations was between 2 & 6% 

https://www.youtube.com/watch?v=0ge2PZIX1oM

I can only think it is to do with how the fuel is produced, i have never seen 91 ron fuel on a pump.

 

Australia appears to add ethanol to it and it raises the Ron to 94

 

Europe adds ethanol to 97 ron fuel and reduces the ron to 95.

 

Therefore i would say that Volkswagen are happy for their cars to run on 10% ethanol but not happy for the engine to have 94 Ron put in it because they are tuned to run on fuel with a minimum Octane rating of 95. So are not recommending using ethanol blended fuels in Australia.

^^^ Lovely leaded petrol.

& when i worked on the Petrol pumps we charged 5 pence a shot for Redex.

That extra pocket money bough my petrol for my moped. 

 

You will not see a 91 ron fuel in the UK, but you will see cars that had that as a min ron they could use on the Fuel Flap, VW being Global. 

 

VW engines in some World Regions in the Likes of a Golf GTI, Poloi GTI are de-tunes for the fuels.

eg, that might be in North America , South Africa.  Fuel, altitude, ambient temps. 

 

It is over a decade since anybody sold 98 ron min petrol in the UK.    *The VW Website was never updated from the 98 ron, or the sticker on the fuel flap.*

Shell went 99 ron Min following Tesco Momentum 99 and BP went 97 the came as others.

Costco has been 97 and 99. 

Esso was 97 and is now 99.

 

We used to buy 102 ron BP pump fuel in Fife an Edinburgh which was great for Knockhill, Crail, etc. 

 

@Winston_Woof i have linked that video several times and also the tuning / dyno vid.

The thing is the Formulation and Bio-Ethanol content does change for the Summer & Winter Spec petrol and Winter spec is first distributed each winter in Scotland and the north of England.

The UK often has Winter spec petrol past March as European Winter fuel is bought and imported later, also from the USA. 

 

 

 

Green flap, VW Sirocco.

Red.  Fabia mk2 vRS 1.4 TSI Twincharger.

Black. As on most EU/European Skoda petrols.
