Aus Delivered 2011 WK2 3.6L E85 Compatible?

Hi all,

Just wanted to confirm or not if any of the Aus delivered 3.6L petrols were compatible with E85?

Sorry if this has been covered, i have searched and there is huge amount of info on the USDM versions, but unclear when it comes to our AUDM RHD versions.

Thank you,

No it isn't according to this:

Can my vehicle operate on Ethanol blend petrol? : FCAI

Quote:
At this stage, very few cars on Australian roads are capable of operating on E85. These include Saab’s 9-3 and 9-5 Bio power models, Dodge Avenger 2.7L V6, Dodge Journey 2.7L V6 people mover, Chrysler Sebring 2.7 V6 (sedan and convertible) and Holden Commodore VE Series II flex-fuel vehicles (with 3.0L V6 or 6.0L V8 engine).

Thank you for that Steve ,

i was hoping for a bit more technical information, Can anyone elaborate on what the USDM versions got that we didn't get?

specific to E85 compatibility.

is it Software related? injectors? fuel pump? all of the above? is there an EPC or database with some part numbers of certain things like injectors etc that have been serviced/tested/cleaned on an e85 US version, compared to some of ours?

Thank you,

Just curious as to why you're interested in E85?

Using it will reduce your engine power and lower your fuel economy.

Mostly due to the ridiculous price difference at the pump at the moment..

But i am curious for future tuning possibilities (high compression low boost turbocharging) that being Ethanol is greatly superior to Petrol.

Re: Aus Delivered 2011 WK2 3.6L E85 Compatible?

After a bit more googling

The Jeep blog itself says the 2011 3.6L is compatible with E85.
http://www.jeep.com.au/blog-news/220-grand-cherokee-36l
Strange I'd read other information that said it wasn't.???

I couldn't find any other reference to its compatibility in Australia anywhere else other than this blog post.

This doesn't necessarily mean the MY14 version is as there might have been some changes in the tuning or componentry / fuel lines etc.


It also seems this article from 2012 says that the 2012 Captiva 5 with 2.4L engine is OK to run E85.
The other one is the Jeep Cherokee (not the new KL version) but the one with the 3.7L engine.
One version of the Bentley Continental 6.0 W12 also can, but that s about it.
It doesnt seem to be too popular according to the article though.

Fuel for thought




The argument for running E85 is that obviously it uses less "fossil fuel" (of course being only 15% petrol), I can see the benefit in that as fossil fuels run out (eventually)

It also that it produces less CO2 emissions for the same energy.

That's true, it produces about 37% CO2 per kg fuel when burning compared to petrol but you would go thru about 35% more kg of it in a flex-fuel car to go the same distance so its only maybe 2% less CO2.
If the car is tunes specifically for E85 then it might be better but still only 2% to 10% less CO2.

The energy per kilo is less because there is quite a bit of Oxygen already in the fuel molecules and this accounts for some of the mass in the fuel.

Re: Aus Delivered 2011 WK2 3.6L E85 Compatible?

Just some food for thought.. i will compare prices i saw 6 weeks ago (before oil prices dropped)

normal plain 91 RON - 1.49/L
at the SAME pump on the same day
Caltex Eflex E85 - 1.12/L

i didn't take a picture i'm sorry.

assuming your daily driven WK2 averages 12.1L/100km.. which is from what i have read a bit on the heavy side (i'm running with what my friends car displayed this morning - only city driving)

you would have to see an increase of well over 16.1L/100km to start to see any 'worse' cost involved..


also -

almost every single 'press release' i have found and read about the 2011 release of the new 3.6L engine for Australia confirms that it's E85 compliant, they usually have a dedicated paragraph on it alone! these are Australian based reviews etc..

just a few that i pulled from browser history..

4WDNews.com.au

Chrysler 2011 Grand Cherokee - Chrysler’s new V6 to power next Grand Cherokee | GoAuto

like many of you i would probly not like to just suck it and see what happens.. the Jeep service guys over here are useless, didn't even know what E85 was..

none of them are willing to help to see if there is actually different part numbers for VIN's that are confirmed E85 compatible (US VIN) vs one of our VIN's.. which is all i'm asking is there literally different fuel pump, filter, presence of an ethanol sensor etc all the hardware missing from the AUDM versions?

Personally under no circumstance would i ever put any amount of ethanol in my car Or any car it is bad news regardless what they say.
My brother was a mechanic who would rise from the grave and kick my head in if i did such a thing
