when using a pecentage , it has to be based on a permament vaue, number etc you cant just say add 5%
its either add 5% of 1 litre or 5% of a full tank or 5% of the carton contents etc
you have to have a base figure to measure the amount of % from
 
anyway
im thinking muman means per litre which in our case is 2.75 litres for a whole tank which im willing to try out
 
see what happens

purple5ive, the whole point of percentages is that they DON'T have to be based on a permanent value.  The value that something is a percentage of is based on each specific situation.  In the case of blending 5% ethanol, that means 5% of the total fuel quantity.  It doesn't matter if the total quantity is 10 litres, or 278,000 litres, you still need 5% ethanol to achieve the same result.  In the case of 10 litres, that's 500ml of ethanol and 9.5l of petrol, for 278,000 litres you'd need 13,900 litres of ethanol and 264,100 litres of petrol.  Both situations are 5% but with very different base amounts.

Zmit: nice link to United, and timely too.
Thats great news. 10% in a nice package, if it's what they claim, and with corrosion inhibitors. That is definitely worth a try, might be a good base to work from when looking at 80/20 too, or higher.

"premium100 is currently only available in Albury & Bayswater in Victoria and now Blacktown (Sunnyholt Rd), NSW. " 
 
purple5ive - thats probably a good starting point, and you should notice an appreciative difference... I did! 

I don't think they would put these locations up for no reason though...

Not good news from United, unfortunately.
 
 
Hi James,

Unfortunately there is currently a shortage of ethanol blended fuels such as Premium 100. For this reason plans to increase its distribution are unclear.

We'll be sure to provide this information on the website when it happens.

No luck for the AW11 owners I imagine, as the engine is basically the same as the old corolla's and they are not recommended to use Ethanol.

I don't see how the AW11 is that much different to the SW20 anyway, as in your case it still is fuel injected. Those older corolla's were most likely carby so thats apparently an issue.
 
I wouldn't take that site as gospel though as it seems a little generalised IMO -  I'd be asking Toyota.

^ Good question, although there's plenty of treated rubber hoses about that are supposed to be alcohol fuel compatible, nice to have a single source and know for sure. Same with pumps. I think the Aeromotive is E85 compatible, not so sure about the newer Walbro..even some filters can be a problem as well, when using higher concentrations of ethanol.
 
Since my last post I've run both 10% and 15% mixes to see what results I'd get.
Seems premium 100 is not an option in Qld in the foreseeable future.
Both of those mixes exhibited the same results as 80/20 in relation to improved low end torque increases, driveability, and responsiveness, as far as I can determine, so I'm assuming 10% using the currently available bio-flex is making 100RON or close enough to it, to utilize the JDM Ign mapping without any issue. The difference is under boost, at higher rpm where the higher ratio seems to come on stronger.
There is a discernable improvement on 10% with spool and 'revability', but this definitely improves as the mix ratio increases. I'd put this down to the benefit of the oxygenated fuel properties itself. Although I still think 20% is as far as I'd personally want to go if I was running stock injectors, and no means of tuning on a stock ECU.
