Is my wk2 flex fuel?

I have a 2011 3.6L LaredoX. The gas cap is a yellow cap with e85 noted on it but I don't see anything else on the vehicle. I've tried the manual but it didn't say anything for my model. I'm thinking the previous owners might have replaced the gas cap, but I thought I'd asked.

Re: Is my wk2 flex fuel?

I believe all the 3.6L engines are flex fuel but it's kind of pointless to burn E85.

Re: Is my wk2 flex fuel?

Yes you're 2011 is rated flex fuel. While I think the 3.6's mechanicals are nearly identical from 11-15 which would make them all capable of running e85, I've read but never truly confirmed that '12 and up differed on the software end and don't have the rating.. E85 will vastly improve the jeeps performance and fuel efficiency. You'll likely be very upset they don't make e100 available as I was today when I filled up today, April 1st.

Re: Is my wk2 flex fuel?

My 2011 had the 6 cylinder and it was "approved" for E85, but I never put it in. There is no point to using it at this time.

Reduced mpg does not equal slightly lower price than regular gas.

Agreed.
Engineer and mathematician here, though I work in IT.
I ran some calculations one day just for grins figuring out the average reported MPG loss using E85 and versus the cost of the fuel....

I don't remember exactly....
But the fuel would have to be considerably cheaper than 'regular' fuel to make it worth your money. With today's low gas prices, E85 just isn't worth it unless maybe it was selling for less than have of normal fuel.

A new vehicle should have a sticker on the windshield that points out what the approximate mileage range would be on a tank of regular unleaded (E10) versus a tank of E85. It is significantly less running E85.

Re: Is my wk2 flex fuel?

Apparently a gallon of E85 does not have the explosive power of a gallon of E10.

You'll actually see increase performance, while burning more fuel.

We don't need no stinkin' stickers!

What we need is gasoline.

Take the corn and use it to feed the hungry.

Take the corn cobs and tell the E85 fans where they can stick them.

They won't need to kill trees to make toilet paper.

Win, Win, Win!
