E10

[itshimdazza]

I have a question regarding E10 fuel.

Now i know that its a blend of unleaded + %10 ethonal and is a lower Octane rating , but i have been searching on the net and discovered the following at "Freedom Fuels" which actually has 3 diferent types of E10...

E10 Unleaded (91)

http://www.freedomfuels.com.au/index.php?option=com_content&view=article&id=15&Itemid=20

E10 Premium (95)

http://www.freedomfuels.com.au/index.php?option=com_content&view=article&id=16&Itemid=20

E10 Hi Octane (98)

http://www.freedomfuels.com.au/index.php?option=com_content&view=article&id=17&Itemid=20

So my question is that would it be ok to use the E10 Hi Octane as its equivelent to 98 proof premium unleaded?

It has ethanol content which will affect the way it burns. Maybe though it could be used, tuned and give better results than regular unleaded... And its probably more readily available

[drift nut]

im also curious on this subject

Any E10 is safe to use and the higher octane the better.

For highly tuned engines the problem is the same as with E85 although on a smaller scale - namely that the actual ethanol content and rating of the fuel can vary which matters when your engine is tuned to the outer limits. For such engines the way forward seems to be the "flexi" approach where the fuel quality is sampled by a special sensor before it reaches the injectors and an adjustment made automatically through your Link, Vipec or other high performing aftermarket ecu.

However for stock or less modified engines the difference particularly with E10 should not be significant.

I'm using the United Premium 100 fuel, which has become available again at my local servo. 100 octane E10, and my car seems to run better on it. Always had good results when running it in the past.

yeah there's no problem running the 98 RON E10. it's just the regular 91 RON E10 that fuels now sell as cheap 'regular' that you need to stay away from.

How is the price of 100E10 comparing with 98?

[limpus]

I ran 100ron E10 for 2 years before switching to E85 because the local servo stopped selling it...car ran faultessly...

If its just 95 or 98 ron then its probably not worth it...

[SargeRX8]

Does it cost extra? If the car is tuned on 98 octane fuel, will it be fine switching to this? Are there any risks of running this octane stuff? I have heard alot of stories of the ethanol ruining old components in the fuel setup, corroding shit, etc. Sure these cars run now but is there any negative long term effects

[JonnoHR31]

myths. e10 isnt gonna corrode anything more than petrol would.

should be fine switching to it, wouldnt hurt to check knock levels though.

[itshimdazza]

so United sell e10 100 octane...might have to check that out and put 1/2 tank in when empty to see if there is a diference between that & vortex..

Thanks for the input guys, would love to do e85 but there isnt much around and cant afford more injectors presently but but the e10 may helpp a bit....

How does it vary in price to the 2 premuim brands & what the economy like guys?

I find the 100 to be similarly priced to Ultimate.

I think the E10 does corrode in older cars. R31s are on the list of cars that cant run E10 (without upgrading the fuel lines), but modern cars are fine.

uh oh, i think thats all that my gf's 31 ever gets

on topic, i run the e10 95 in my stagea (way cheaper than the 98 we get here) and it runs pertty well (rb25 neo)

[JonnoHR31]

31s can run e10 no worries. they have the same fuel hoses as other skylines, they're just a little older. if they corrode they were already f**ked anyway and should be replaced.

[limpus]

^^^

Agreed...I have a R31 at my place which lives on E10...no issues there...

[bigkevracer]

Funny, I remember it being in one of those government pamphlets when E10 first came out as being on the 'do not use' list. Maybe it was just paranoia on their behalf? I never bothered to double check it, just didn't use it.

[dori34]

will the car need to be retuned to run E10 98ron?

I asked above, apparently not. Just monitor knock. if I seea station with this fuel ill give it a try.

let me know how you go, see if you can put it on the dyno to see if everythings okay.

[JonnoHR31]

aslong as the octane is actually the same as whatever your cars tuned to suit it'll be fine. the afr's shouldn't lean out by more than 4-5% which is nothing.
