On an FX4 it is $2395 more than the Eco and $3490 more than the 5.0
On a Lariat it is $3150 more than the Eco and $4245 more than the 5.0

I know the 6.2 is more. I meant the eco is a couple Grand more than the 5.0 and probably 4 more than the 3.7, I don't care about the 6.2 in this example because no one has one. And that's why the eco isn't flex fuel because then it would be even more expensive than it already is was my point.

NASSTY

The Eco is only $1095 more than the 5.0. and $2395 more than the 3.7.
If you are trying to make a point you should do a little research instead of pulling these outrageous numbers out of your ****.

Hahahaha!

That doesn't include those of us that got it for only 750 above the 5.0.
I wonder if they're offering those discounts still?

There isn't a lot of E85 in my area so I can't comment on the op's question. Not that I'd run it in my Eco but I would've tried it in my old truck.

tried a tank in my 2009 flex fuel. The way the fuel economy dropped, you would have to be able to buy it .50 a gallon cheaper to break even. Even then you would have to contend with lousy gas mileage.

SultanGris

It doesn't matter what the number is, my point is that making it flex fuel makes the number bigger!

I thought the Eco couldn't use E85 because the injectors won't spray enough. Doesn't make sense they'd use different fuel lines and containment than the other engines.

SultanGris

Well they do because ethanol eats the rubber gaskets and hoses normal non flex fuel vehicles use. Injectors not spraying enough fuel isn't the reason, an Eco would run just fine on e85 but your fuel lines would eventually crack and leak.

Edit: I guess it doesn't technically eat it but it drys it out and causes it to eventually fail.

I'm pretty sure that running e-85 is bad since it does require more fuel meaning bigger injectors... I also am pretty sure when you run e-85 the truck recognizes it and changes the tuning... At least that's what I've read on here... Not saying the prongs and rubber pieces have nothing to do with it cause im sure it is a more harsh fuel

SultanGris

im not recommending running e85 in an eco by any means, im just saying that it would run on it. Yes it takes about 20 percent more fuel but as much fuel as an eco sucks pulling 11,000 pounds im pretty sure it could handle the flow rate. I could be wrong, but i doubt it.
