E10 Fuel

[Bruster]

Hi Everyone,


i have been a reading alot on this forum but hardly make any comments.
But im due to take possession of a 2006 accord Euro luxury from a family member and have a few questions.

I have done some research and i have found that Euro can use E10 fuel
not sure if economy suffers or if power suffers as a result of using it.

But since the government will make compulsory 10% ethanol in petrol within a few years i thought there is not much we can do unless we buy a diesel.

anyways my question is Any performance benifit? economy? and maintenance issues?

hopefully someone here has tried and tested it.

cheers
Bru

I'm pretty sure someone here has used it, but from my experience with a different car (not Euro), performance and economy both suffer. But I haven't really calculate whether the degradation in economy (ignoring performance degradation) is gained through the cheaper price.

ethanol produces approx 30% less energy than regular petrol.
at, say, 145.9 cents per litre for normal unleaded, E10 will cost 143.4 (it is 2.5 cents cheaper.

Now, E10 will have 3% less energy than regular fuel (10% ethanol, with 30% less energy)

so, the discount as a percentage is (145.9-143.4)/145.9. Thats 1.7%

So, you get 3% less energy, yet you only get a 1.7% discount. Sound likes your 1.3% worse off.

Not to mention that the euro requires 95RON or above, and E10 is only 93 octane.

Please dont use it.

also it is compulsory in NSW already.

alot of people claim it 2-3 cents cheaper.
actually its not, bare in mind euro uses premium unleaded depending on the service station can be 5 - 10 cents more expensive than unlead petrol
the E10 being 2-3 cheaper makes it a substantial 7 - 10 saving per litre when compared to premium

i work for mobil. its 2.5cents cheaper than regular unleaded petrol at mobil, that is a fact.

youre right - the euro does use premium unleaded. so E10 is too low an octane rating (93, when the euro needs 95 or above) - you shouldnt be using it in the first place.

using a petrol with a lower octane rating can actually give you less power. higher octane fuels burn more slowly and are thus ignited earlier in the combustion process. by using a lower octane fuel that burns more quickly, you risk reaching peak cylinder pressure before the piston is at top dead centre.

this is not good for your engine.


oh wow. 10cents a litre. on a 50litre tank thats $5. if you fill up once a week thats $250 a year. if you can afford a euro you can afford $250 a year.

Someone will come in and say that high octane fuel does not burn slower, which I will agree with.. High octane is more resistant to self ignition. That's it.

and irrespective, the bit about it yielding less power was more to do with the fact that i was recommending he use 95RON or above, as suggested by his owners manual.

what you said isnt relevant at all to the OP's question

Man before u start claiming this. U gotta realise more than one place exist.

United petrol sells E10. For 3c and guess what. its 95RON.


I used E10 for about 6 months in my EG. After some advice from a friend to try 'normal' petrol again. i noticed i could get and extra 40-50ks from a tank.

So it ended up not really being a saving at all.

That first link has so many errors... .Knock occurs when cylinder pressures are high? OMG... that's silly. You can get knocking with a low compression engine as well with low cylinder pressure,.
Also, flame speed is not directly related to octane rating. Other factors affect flame speed more than octane rating.

From my textbooks at uni, octane rating measures just the resistance to autoignition.

Good read on octane rating - http://www.thor-racing.co.uk/Octane_Rating-149.asp

And no, I wasn't answering the OP's question. I was starting a discussion on the contents of your post.

E10 wears out the rubber components in your motor quicker, i wouldnt touch it

[tron07]

To me, E10 fuel are not cheap enough to justify using it....
