I’m all about clean burn, will I be able to use super and e85 if I converted/switched?

You can run it now even if you are not FF.  My 2002 isn't and I run it with no problems.  I don't get the performance benefit but I do get the clean burning as well as the higher octane.  I usually run a 50/50 mix in the winter since it does tend to start harder at temps below 38°F.    I have been running it now for 3 years with no issues.

There are three reasons I want to be able to run e85, it can make more power, it is readily available in Illinois, and its cheaper than 87 but has over 100 octane.   I've been running e15 in

Well I have since added a recalibrated thermostat 180-190 that gives me a good temp drop but not too low so cold weather driving and the Air Raid modular intake pipe. I started changing parameter

Agree, but there is an advantage to running E85.  It burns super clean. So carbon buildup is not an issue. Another one is the higher octane, and one other thing, at least for me.  I like the smell of

I’ve got a 100K extended warranty on my 6.2 and don’t want to deal with reprogramming the ECM. I may go put $10 worth tonight heehee

Maybe this is a question for Karnut, he’s very familiar with E85.

 

Can you run 20-50% E85 in a 5.3 and 6.2 without retuning your ECM??

The “Flex” in Flex Fuel means it’s flexible and able to burn regular fuel and ethanol

Yes. The flex fuel sensor reads the alcohol content and automatically adjust the tune for it.

I know that, can it be mixed in with super or regular without being flex fuel?

Yes. But there is no point. You either run gas or E85. No need to blend fuels. 

 

Only reason to blend is if your fuel system couldn’t handle a high percentage of E

I’d like to just run e85 whenever but I don’t have a 6.2 flex fuel kit yet and the question was if I need a conversion kit for my 6.2 before I can run E85?

Wait my reply to you was if you had a flex fuel capable vehicle. If you don’t then running E85 is a complete waste of money and will hurt the performance of your truck

Yes you need one. It’s absolutely pointless to run it if the ecm won’t adjust. There is no benefit at all. It will actually hurt your performance.

That’s what I wanted to know. Black02silverado says he uses it in his older 6.2 all the time with zero issues hmmmm

I ran E-85 in my 14 because it came capable and using it would give additional HP. It seemed to like it and I could get it cheaper that reg sometimes definitely cheaper than premium. I would usually tune my truck for premium and get the boost in performance that way. I did tune the transmission and turned off the cylinder deactivation. I did raise the shift points and RPMs and set the transmission at 50 percent TM. Every thing I’ve read says don’t put E-85 in a non flex fuel vehicle.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
