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.

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.

    • Hey mate, thread dredging hahah To answer you directly, yes I had my itbs oversized and custom butterflies etc made by EFI Hardware in Sydney back around 2017-2018 if memory serves. My setup had a vast amount of other changes too though, so no direct comparisons unfortunately. i went from oem itbs, HPI manifold and internal gate hks 2835 pro S; to 49mm itbs, cnc port matched Nismo plenum, RB25 Neo lower runner adapter hand port matched, r31house v2 Takoashi MAX equal length twin scroll manifold with twin 38mm tial gates and a FP HTA3076 with 1.01ar twin scroll real hosing. feom power Fc to a link fury wired by 12volt, r32 gtr fuel tank conversion with frenchys twin 460 / surge tabk fuel hanger combo kit, 1659cc injectors, full 4 inch turbo back stainless exhaust, Z34 6 speed, Tomei 2way with 4.3 final drive and a ton of other shit. ive posted elsewhere here with complete run down, but here's a graph from its initial tune with no boost control on, 20psi gate springs only and e85.   IMG_1267.mov 7542AE72-DA92-4E0B-8660-B0940FEA7F24.mov B31A1E84-C63C-433F-B910-1A09DBAE2107.mov
    • On sale mate, $55. Sorted. https://www.supercheapauto.com.au/p/toolpro-toolpro-torque-wrench-1-2-drive/565734.html?utm_content=paidsearch-pmax&gad_source=1&gclid=Cj0KCQjwytS-BhCKARIsAMGJyzqYEnwWmhWf6gxTST_Nz06Gd2VePgyvL7lh6PWrQtbjXTsI6TqSCLEaAuaCEALw_wcB&gclsrc=aw.ds
    • Slap it and say it ain't going no where, you'll be fine.
    • So the whole rb25de neo setup was a tiptronic setup and i swapped everything over to my rb20de neo setup and yes even the cluster of the rb25 was swapped over. 
    • and I thought size mattered 😝 At this point I may either pray to the Afterpay gods and get a torque wrench or attach a water bucket to the breaker bar. I appreciate the help though 🙏🏾
