First things first this is only occurring in Arizona right now as far as I know. I am not sure about other states, but I wouldn't be surprised if this happens nation wide. According to a new bill called HB2171, E85 will cease to exist and it will be rebranded as Ethanol Flex Fuel and be lowered to E54. Pretty annoying if I say so my self. My Evo X is on TephraX3 with flex fuel so this isn't an issue but it looks like I'll be needing a retune on my IX in the near future. Just wanted to give everyone a heads up in case this does become a national thing. Would really suck to start seeing a bunch of blown motors and what not due to a lack of information.

 

Thanks, I am going to look into for Texas

 

Please do! I live in TX (south of Houston) and I'm building my 4B11 for e85!!! 10:1SCR

 

91 is the best we can get here and now E85 is getting "watered" down. That's a bummer.

 

I hope this doesn't spread but by the sound of it it doesn't look that good...

 

Interesting. I want to bump this for more input.

 

im switching over to E85 next week lol

 

My local pump in nor cal has the sticker on it. Filled my tank and my ECA is sayin E72. Ill update with the next couple fill ups to see if there is a wild fluctuation.

 

 

That is most likely just a winter blend. My e85 station did the same thing. Dropped it from 82ish to 72. It helps the car with starting in cold weather climates

 

To be accurate they should relabel pumps to E-WTF because you never really know what you're getting. The solution is to regularly test your local fuel. It doesn't have to be lab grade, but just so you have some kind of idea what you're getting.

 

Is this because of the possibly high impact ethanol production has?
