E85 issues in 2022 3.6L etorque

[Bleda2002]

I personally think it's best to run the lowest level of ethanol possible (unless you're specifically running an E85-tuned vehicle), but you could try the cheaper E15 (Unleaded 88) since that's approved, if you have it in your region.

Right now it's only 30¢ cheaper per gallon versus Regular 87, but over the summer it was almost $1/gallon cheaper. It'll likely get you much worse fuel economy, so unless it's a big difference in savings it's probably still best to stay with 87 and keep a light foot.

I worked this out when gas got crazy to see if it was actually worth it in my area. Because normal gas at this point is 10% ethanol, e15 actually only has to be like 2-3% cheaper for it to be a better deal as it contains about 2-3% less energy per gallon.

….I’m like “man, I must be an idiot. What the hell is E85?” Turns out I wouldn’t know because only four gas stations (not four franchises, four little gas stations) in all of Canada sell it, and they’re all in BC.

I put “Regular” in my 3.6 with etorque (87 Octane). Mid grade is 89. Premium is 91 and Ultra (where it is available) is 94.

85? That’s some ghetto gas, that is.

The 85 is for 85% ethanol vs the normal 10-15% blend you commonly find. The octane rating is actually quite high and is over 100, which is why some of the race guys love it if they are tuned for it.

Think it varies by region, but iirc, around here we have 'up to 10%' ethanol in regular and that's only during the winter, with lesser amounts blended in during the summer. In my car, the winter blend usually equates to a 3 to 6 mpg drop in fuel economy, which is a 15 to 25% decrease (though tbf, some of that loss is from longer idling during warm-up during the coldest part of winter).

98% of US gasoline is 10% ethanol, even in the summer you're getting 10% ethanol at this point unless you specifically fill up with non-ethanol labeled gas. The winter/summer blend mpg difference is actually because winter gas ups the percentage of butane

85% Ethanol? Yikes. When ethanol blends were mandated here back in the 80s (5% blends), they found them to dry out seals in the engines and literally dissolve some plastic components of the fuel systems. If an engine isn’t designed to run an alcohol, I can see how that high a percentage would be a major problem.

Flush it, OP. Immediately.

This is so bad, that I won’t even comment on it..

There is literally a guy in here who runs E85 and has a tune for it. The JL is apparently plumbed for E85 because a couple of the markets outside of NA use it more. Get some normal gas in there and run it through. You should be fine.

Definitely don't tell the dealership you filled it with that though. They will use that to void the warranty on anything they want.

So we had flex fuel vehicles for work. E85 sucks sure it's cheap but you get crap for mileage so have to fuel twice as often.

I've run E-85 in my flex fuel Tundra twice. The first time was to try it out and the second was because we had a massive fuel shortage here on the east coast and that's all I could get. Both times it sucked. Mileage was horrible, truck ran like shit and took a month to get back to running right. I will never run it by choice again.

Never have I seen anything that E85 is approved for the 3.6.

My 2007 Ram had a 4.7L and my 2013 Caravan had the 3.6 which both were actual flex fuel and built for this stuff. The Ram would easily kill the Hemis with it and the van had an equal boost
Mileage did drop about 35% and only a few stations sold it priced accordingly so it was a rare treat
Besides, that van had a bitch of a time starting under 30 degrees with E-85- and it was a new car !!!
As far as this story goes though - didn't we go through this just last week with someone else ??? - stupid both times but - live and learn I suppose and he should be razzed by all you guys for this too !

Lol, I wouldn't cheap out on this 1 and just pump it out, I wouldn't even dilute it, that stuffs poison on a good day with a vehicle made for it. Just suck it up, regret is as a stupid experiment trying to do things cheap, and go fill your tank back up with some proper fuel. The engine isn't a great place to experiment with.

I hear canola oil is cheaper than motor oil, maybe try that on the next oil change…. ?‍

I don't understand why gas stations and automotive manufacturers with flex fuel engines don't make a unique fill port / nozzle so that only E85 rated vehicles can accept E85 fuel? Just like they do with Diesel and Gas ports/nozzles (here in Canada at least). The different sizes prevent someone from filling a gas engine with diesel (as the diesel nozzle is too wide to slide into a gas fill port). If this stuff is poison for non-flex engines, it should be treated as such. Warning stickers won't do - you gotta make it fool-proof for John Q. Public.
