Hi guys important question I'm not really sure I might need to upgrade to  a Octavia vRS  2.0 19 plate my question is can this vehicle run on     E10      petrol all will I have to use super unleaded as in   shell v Power might go for the petrol version hoping against hope I can running on E10 but there again High performing engine if might not work it might require Shell V-Power all the time works had a lot expensive all inputs would be welcome for future decision

It will be fine on E10.

As above my vrs runs perfect on e10 .

It's only if you have your car remapped, that you really need super unleaded. 

I wouldn't use E10 because it absorbs moisture & causes corrosion from what Ive been told. I personally think it's a tactic being used to get petrol cars off the road & the same for diesel. Goverments wanting everyone in electric vehicles is another scam me thinks 🤣

Pure ethanol is hygroscopic which means it will absorb moisture from the air. That's just like most brake fluid hence the need to change it every few years.

 

Once mixed in with the other components in petrol, it really shouldn't cause an issue if the car is in regular use. If it's an older vehicle that's laid up for half a year with a steel fuel tank then it might cause a issues. To be honest, it's more likely to finish off old plastic/rubber components but they are probably due for replacement anyway... 

 

I use E10 in my '69 Sprite without any negative effects. When I dragged it out of hibernation this spring, it happily started on the first turn of the key with half a tank of months old E10 - no water/rust etc in the fuel filter 👍

They have "E10" on the label inside the fuel filler cap. . . Although e10 is "new" here in the UK. . . Its been common place in alot of Europe for a while. .so the cars have been adapted to run the stuff long before we got it over here. . 

 

As for running "performance" fuel. . I've dropped shell vpower for tesco momentum. . About 8-10p per litre cheaper!

I'm trying not to be too much of a conspiracy theorist but I have a few questions about e10.

Where all this 'green' ethanol is coming from? Especially now that the Russian invasion has suddenly reduced the world's marketable grain supply by about 30% (that is Russian and Ukrainian exports which I think also fed approx 400 million people). Does it come from destroyed Amazonian rainforest?

Where are the factories based that produce the ethanol? It would have to be a pretty massive production capacity.

When and where does it get mixed with the petrol? At the producing refinery or at the distribution point where they usually add the added chemicals (for 95 or higher RON)? My guess is the latter as the ethanol content could determine the amount of aromatics, detergents and knock inhibitors added.

How are the Euro/UK regulations regarding e10 worded? Is the 10% ethanol content fixed in stone or is it a maximum or minimum amount?

 

I guess I am suggesting that the ethanol content may not be as large as generally thought, which would partly explain why the reported effects so far are minimal.

In the UK & EU E10 means a maximum ethanol content of 10%, so in theory it can be anywhere between 0% and 10%.

Ethanol for the UK was going to be coming from producers of Bioethanol in the UK.  But the UK government kept pushing back on the 95 Ron E10 becoming what had to be on sale.   The companies never got the support from the UK government meaning the companies struggled.    New times, Brexit, Covid, wars and the UK will do trade deals, just not EU ones.    Times will change.

A similar story here with Australian ethanol producers lobbying politicians on both sides of the fence and donating to both, to at least make ethanol a legal addition to fuel.

I won't say 'corruption' but the process was certainly corrupted.

Partially correct. Yes, the maximum is 10%. It also has a minimum ethanol content to meet in the UK, IIRC it's 5.5%.

 

Unsure if other regions have similar minimums. 

 

Edit - as per below, from The Motor Fuel (Composition and Content) and the Biofuel (Labelling) (Amendment) (No. 2) Regulations 2021

 

Amendments to regulation 3

4.  In regulation 3(2)—

 

(a)in paragraph (2), for “Annex I of the Directive”, substitute “Table 1 of Schedule AA1”;

(b)in paragraph (3), from “Annex I” to the end, substitute “Table 1 of Schedule AA1”;

(c)in paragraph (4), for “Annex II of the Directive”, substitute “Table 2 of Schedule AA1”;

(d)in paragraph (5)—

(i)omit “before 1st January 2017”;

(ii)for “3” substitute “1”;

(e)in paragraph (7), for “Annex I of the Directive”, in both places it occurs, substitute “Table 1 of Schedule AA1”;

(f)after paragraph (7) insert—

“(8) Premium 95 grade petrol will not comply with a specified requirement unless, in addition to the requirements of paragraphs (2) or (3), it has a minimum ethanol content of 5.5% by volume measured in accordance with the test method referred to in Table 1 of Schedule AA1.”.

Aside from the political debate, of which there are many elements that have been stressed lately, and the technical debate on the actual levels of bioethanol (if it is even bio) - I use premium in my GTE as I can go many miles without putting fresh fuel in. I may be barking up the wrong tree as the fuel tank in a phev is more sealed due to the length of time it can stay in there. As a result the fuel has less chance to breath with the outside world.

 

On a side note: how does E10 compare with E85? Is the 85 bit the ethanol so up to 15% petrol? Or is it 15% ethanol (minimum?)?

E85 is nominally 85% ethanol and 15% petrol. 

 

The number after the E is usually the expected/maximum ethanol content as a % by volume. 

E85 has been common in some European countries and also America for many years.

 

I ran some trials on an E85 Saab imported from Sweden many years ago.  The Ethanol content means the fuel has a lower energy content than normal petrol and so you need to burn more to get the same power, hence why the fuel consumption gets worse.

 

But the Ethanol provides a greater octane rating and so the timing of the engine can be advanced further and hence more power generated.

The Bio-Ethanol that is sold at the pumps in my area has the ethanol component coming from the betteraves (sugar beet) that are cultivated all around me, they are no longer viable for conversion to sugar because the unlawful subsidies were finally removed so most of the Sucreries are now producing Ethanol and other by products.
