Can bad gas cause engine problems? Of course it can. Could ethanol be causing the issues present in these engines? It might be. Should it be? Absolutely not.

Please, just quit while you're behind.
It does not matter if I am correct or wrong on this matter. Because your going to do what you want to do as well as i at the end of the day. If this topic upsets you, then I will quit sharing my idea and studies on this matter.


But in closing, studies I find on the result of Blended fuels as gas-a-hol, have proven over and over to cause these results in modern combustion motors Unburned hydrocarbon emissions , from this fuel,and molecules in the engine that do not burn or burn only partially,could be the cause of ignition misfires, low compression, oil leakage past the rings or valves, or excessively rich mixture? Now is it true that the majority of the codes flashed on these pentastar engines are in the neighborhood of misfires? I see a common bond here.

With this lil tid bit of the info,and other info i read over the pas 3 yrs I will go.

Peace.

Wait. Now E10 is the reason the roads are littered left and right with broken-down pentastars?

That ticking will get progressively worse until eventually you get the P0302 error or something similar. The Jeep will still run fine, but you will notice a slight hit in fuel mileage. I know someone with a Feb build date that just had a head replaced. They only recently determined the cause and I don't think they have implemented a fix in production yet. My driverside head was replaced a few months ago and mine is starting to tick again. I'm guessing that around 25,000 miles, it'll start to throw codes again.
I have the 3.6 pentistar in my 2012 caravan and recently got a misfire code - the dealer replaced the head to fix it now I get sucky mileage and less power...started at 35k

In doing research this affects jeep/Durango/ and any auto with this motor also I read that it is due to bad castings of the head..

Research? Yes my favorite word! As well as Trial / error.

I as a Former Ford/ Chevy man, I have no beef with Chrysler! After GM and Ford stop backing their product, I was very happy to go to Chrysler! I have had 4 vehicles made by Chrysler since, I am much better off imo. The only concern I have had with Mopar in the past was the 2011 Ram express. Something was never right about the down shift on that truck. However it never threw codes, so hey score one for Dodge. I am very concerned about the recent recorded complaints on the 2013 new redesigned heads throwing codes I put 30 k on my 2012 Jeep with out a hitch. Why is it that my jeeps 2012/2013, has not thrown codes after 20 k plus? I say lets keep searching ! Peace.

Good advice.

After looking around for more Chrysler tech talk, I found this post....."A word to all about the flexfuel usage. Read your owners manual (download it from the internet) and the User's Manual. There are some things you need to know before filling up with E85.
The 3.6 is a winner! "

Yes that is to those that test this crap gas in a lab.
I am not going to harp on the harm this fuel does to engines anymore on this thread.
But I will post this scientific study.
"Ethanol is more corrosive and burns hotter than gasoline, properties that could cause some engines to stall, misfire and overheat,"

/035205_ethanol_gasoline_engines.html#ixzz2qP8qwtX0

I have been paying strict attention to the accounts in here on the signs and symptoms of the Pentastar failures. Did that quote MISSFIRES ring a "bell"?

Look if my positive testimony on the two jeeps I had in the past with "real" gas does not turn your opinion. Let a scientist at least speak his mind.

The link isn't a link.

There aren't any flex fuel wranglers.

Plenty of 3.6 wranglers run E10 without issue.

You're beating a dead horse.
We get it, you don't like ethanol.
