No. There is no such thing as "BAD" E85...... IF left open to the environment, alcohol evaporates faster than gasoline. Therefore, your Ethanol % would drop, creating less demand from you fuel system.
It can separate the base chemicals that keep the ethanol dissolved in the us gasoline. When it gets like that the car won't crank.
We are talking massive amounts of open air environment here........Separation takes MONTHS upon MONTHS to even separate. 12 months minimum.
First experience I was there, buddy said he didn't crank it for a month we flushed it put in fresh from the pump e started up immediately.
It could be bad E yes. BUT with bad E your knock sensors are more likely to go crazy because the Ethanol mixture doesn't have enough octane.
That’s just rubbish. We’ve had cars sit with E85 for 6 months every winter and fire right up for years on end. if a car won’t fire after a mere 30 days of sitting, somethings seriously fubared.
I think by "bad E85" he means when the pump isn't quite at 85% ethanol. There's a bunch of E85 stations near me and one of them is consistently between 85%-90% and I've never once seen it below 75% so it's safe to say that you'll get pretty good E from there (Propel). However, just one exit down the freeway there's another station that also has E and I have never seen it even reach 85% (Shell but the E comes from Pearson Fuels). I go there a lot less because the Propel station is usually spot on, but the few times I've went it's usually below 60% with the highest I've ever seen being 72%. I would consider anything below 75% to be bad E.
My car sat for 3 weeks and she struggled to start lol eventually we got there but yeah, leaving E to sit is no joke.
It was also 25 degrees outside which could have also been the culprit.
Dunno I saw it though, I don't think for a second that all formulations are the same. I do think something was wrong in both cases. It just so happened to be the same shit.
That’s the problem with educating people of fuels and the meaning of them. No fuels are “bad” currently at the pump. Why would you consider an Ethanol/gasoline blend “bad” at under 75% ethanol? Do you even know why? Just because a certain station or pump has less % of Ethanol content doesn’t mean it’s “bad” fuel. Technically, I would consider a E70% fuel “better” than E85.
