First time testing E85
I bought my first round of E85 about two months ago (65) gallons. I wasn't able to get a quick test tube till recently. And Ofcourse today I put the last of it into the car. But before emptying the barrel I took a sample.
Is this normal to be this high???
And a second test

Higher the better right? I'm shocked with it being two months old that the % hasn't dropped. I Def did not think it would be higher than 85%. I'm curious to see what this next 65 gallons tests to be.

Higher will make slightly more HP.
Percentage is not going to drop.

You said it will give you slightly more HP, Does it also give you a little more detonation resistance as well? Even though I've yet to hear anybody have ANY detonation at all with E85.ツ 2003 Redfire Coupe #4319

Make sure you shake it very well, it should separate quickly. I stared at mine for 5 minutes before I shook it in anger and then felt like a dummy.precision turbo 7675 | custom cg fabrication kit | built 4r70 swap by darrin@bc auto | corn fed

How do you guys end up testing it when at the pump i am assuming you bring a can to put a testable amount into test it then fill up?2015 Competition Orange GT (not TVS fast but loving it!)

Dump whats left in the jug in my car and throw the cap on that and in the trunk it goes.

I don't shake the test tube. I just turn it over back and forth a few times. If you shake it too much it creates bubbles and takes longer to settle.
Either way it really doesn't matter because it will give you a close enough reading.

another great tip 04sleeper gave me was to use distilled water instead of tap. I fill up to the water line before I leave my house, that way I'm ready when I pull up to the pump. I fill to the e85 line with a flexible, disposable plastic cup. I have noticed that using distilled not only settles out quicker....but the line is highly distinct and very easy to read.
filled up today, $2.75. tested perfect, no e70 switch happening here

the part that separates to the top... Is that the gasoline part of the fuel or the water you just poured in?? I thought the ethanol would absorb the water and the stuff at the top was the gasoline.. also since water is heavier than oil and gasolineThe best thing since slice bread... E85!!

The top part is the amount of gasoline. The water and Ethanol mix which is below the boundry line.

out of curiosity, if you were tuned for 90% e85 and that was mid summer, say you were to take the car out for one drive before winter, would the car run extremely rich?

Yes if the alcohol percent is less it will run rich.

i wonder how much. Like if you're tuned for wot around 11.7 (90% ethonal) and you fill up with 78% percent, would you jump alll the way down to 11.0 or less???
