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?

Regards,

Darren..

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.

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

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?

Regards,

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)

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.

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
