Nice to know what you think of our lowly, slow, under powered trucks.As stated above, not ideal. But not insurmountable. If the TRX can handle it, then the peasant 5.7L Hemi can as well.

All gasoline powered cars and trucks produced since 2001 can run on up to e15. It's not ideal, but it shouldn't hurt anything in a vehicle that used regularly. I wouldn't fill my tank with it if I was planning on storing my truck for any length of time though. There is some fear that manufacturer's may void warranties if gas containing more than 10% ethanol is used. I'm sure it's spelled out in our owners manual or warranty information. And you're right, mpg will suffer a little.
50% more ethanol is absolutely going to negativity impact mpgno mpg doesn’t suffer

From my manual
5.7L Engine
Do not use E-85 flex fuel or ethanol blends greater than 15% in this engine.
I wonder how it would run tho. Will it ping and run like cr@p? Will the ecu put even more timing? Hope I never have to find out
There is already a long thread about this, pretty sure you commented in it, with several people verifying it doesn’t affect mpg going from your normal 10% e blend to 15% e blend. And those who say it does have a negative impact never tried it for a long period of time.
15% e (88 octane) is also about $0.68 cheaper than mid grade and runs similar, so even if there was a slight impact, the cost savings still out weigh it.

I'll probably just stay away from it if at all possible. Hope we never have to find out.Yes it will run like crap and could harm your engine since it doesn’t have the sensors.
You can buy a flex fuel conversion for these trucks, it’s basically an inline fuel sensor, since the injectors, and fuel pump can handle it. And you instantly pick up 30ish hp by running e-85. But the kit is around $1000.

Will it run noticeably different? No
Will it reduce fuel efficiency? Yes
Price difference between E10 and E15 varies by region. If you can get it $0.68/g cheaper then that would absolutely offset the lower mpg.
Around here (Chicago area) E15 is only $0.05/g cheaper
Huh. Seems pretty common around here. But I don’t use it.Also to note, there are only about 2300 stations or so that sell E15. You'll have to look for it. I think there is one gas station near me that carries it but Costco 87 is still cheaper, and a top tier gas.
