Where to buy good E85 in Melbourne?

Recommended Posts

Hi all.

 

Having trouble finding E85 that's over about 78% Ethanol from United.

Does anyone have any experience in some decent stuff?

I haven't tried Just Fuels in Sunshine yet.

 

Cheers

from all of my experience with E85 in Melbourne it's all around the 85% mark at United's... are you sure it's not your measurement device that's a little off?

Hmmm. I hope it's not the measuring device. It's a brand new Innovate Motorsports one.
I've got some graduated glass cylinders so I'll do some testing of my local United.

alright... hopefully they haven't dropped off their percentages... surely we'd have heard about it if they did.

Most people dont have gauges or sensors that show ethanol content. Like me,  I just fill up United e85, get tune, go fast, fill up. Do skids, fill up. Blow something up, blame skids. Not fuel. But hopefully United hasn't got slack and dropped their ethanol content. Does ethanol content change if it sits for a long time?

Yes. As it absorbs moisture the ethanol % reading will go down. Weather or not having water in the fuel actually changes how the fuel performs, I do not know.
United only guarantee over 70% for their E85 apparently.

Ok I must be doing something wrong.

I put 100ml E85 in a graduated cylinder.
Then I put 20ml water in.

Shook it up for about 30 seconds. Waited almost 10 minutes and all that separated out was as below.

Hmmmm. What did I do wrong? ecdd51e63270f629bf781fb65aa0a572.jpg

Not sure.  Just buy the proper kit.   It is labelled for the correct percentage.

That won't really change anything. It's just a different sized vessel with some branding on it. The concept is exactly the same.

The issue above is not with calculating the ethanol % (that's pretty easy to do).
Just wondering if I shook it for too long? Or not long enough? Or maybe I need to leave it for longer?

It just felt weird standing around a petrol station forecourt to 10 minutes staring at a glass tube so I called it quits. I think the Indian bloke behind the counter thought I was making a bomb haha

Ok so 15ml of water, 45ml fuel.
I get a separation line at the 54ml mark.

According to the below calculator that is 86% which I don't believe. My flex fuel sensor suggests around 79-80% from that station.

Hmmm tried again with 70ml fuel and 25ml water. Separation line at 85ml. According to the above calculator that's 86% still.

Not the dual %/temp one and you've got it set showing temp in degrees F ?

Haha no. It's the 4 in 1. Boost, AFR/Lambda, fuel temp and ethanol %

 

Yeah. I seriously doubt the United I go to has 86% E85. I guess the ~79% showing on the flex fuel sensor is accurate and my measuring is not
