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

And I’ve argued with him about that on here before. He shouldn’t be using it but it’s his truck so whatever. Apparently he’s an environmentalist and cares about his carbon foot print over anything else. 

You don’t run E85 in a vehicle not equipped for it

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

At the least, you’ve got to give him credit for doing what he feels is right.

I did in the other thread. 

 

It’s still not a good enough reason to run fuel in your vehicle it’s not designed to run on.

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?

I believe the possibility exists that it will run very lean as it wont be putting in enough fuel, if the % of alcohol gets way up there.  e85 is general 53% to no more than 83% alcohol, so it depends on where you get you e85.

I appreciate it and I’d jump on the flex kit just to have options but not going to jeopardize my 100k extended warranty.

You’re one of the lucky few...nearest E85 around here is in Tallahassee (160 miles) unless something has changed since last October. I would convert my 6.2 today if it was readily available. The E85 locator shows it’s here but it’s not right unfortunately.

In Navarre, there's a Circle K/Exxon that shows they carry E85.  Over in Oyster Bay is a Shell that carries it and another and a Pride on 181 between Clay City and Belforest.  Probably not convenient.

I'll check it out, I go through Navarre quite a bit actually although highway 98 this time of year is horrible. Thank you!

Well I wanted to reuse the current front engine fuel line, but there is no easy way to bend a 90 degree bend and then out a push connect flare on it.  So, I've decided to cut and use a singe Stainless 90 degree compression elbow in front of the sensor.  It should be here next week.

Just finished installing it and testing for leaks so far so good.  I will program the ECM now to see the Sensor.  

 

I would have preferred to bent and flared the existing line but in the space it was impossible.

 

I did put loktite on the stainless elbow threads so it doesn't vibrate loose.

Just took for a drive and looked for leaks, no leaks.  Programed the ECM and t saw the alcohol content at 11.8% which is about right since I use E15 usually.

Well I have to wait for my tank to go down so I can fill up with E85.  Here is a picture of the fitting I used, I repurposed the quick connect fitting from the old line I cut.

I put about 6 gallons of E85 in to fill the tank.  It is now showing about 30% Ethanol.  It seems to have a little bit more torque and able to stay in V4 mode longer before.  I can't wait to get a full tank of E85.

I'm happy with the conversion so I decided to order the OEM front uel line as well and install, it was only about 55 bucks.  Total cost of the parts is about $130 or so, big cost was the HP tuner.

I've read that the Gen V 5.3 motor stays in V4 about 50% of the time on gasoline.  These make about 44 horsepower per cylinder and on E85 over 47 hp per cylinder.  Custom tuning may eke out even more performance.

 

My Gen IV 5.3 does really well mpg wise between 20-30% alcohol content, better than on gasoline according to the last 4 tanks of fuel.  Power wise, it loves 80% and gets 2.82 mpg less than gasoline for an average tank of fuel.

      Oil pump noise was discussed before.  I will try to remember to record a remote start later this morning.

      MPG at 600 miles

      By Chuck FB · Posted

      There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65

      Factory front brake rotors...defect?

      By Chris80s · Posted

      On my wife's 2020 Blazer (~69000 miles), we started to notice the brakes pulsating at faster speeds. Typically around town you don't notice anything, but highway/interstate driving you will notice it. I decided to pull of the front tires and look at the brakes. I figured with the milage, the pads should be wearing out to their life span, but they actually looked decent. Still with "meat" on them. One pad has a ridge wearing in it, and that same rotor is showing the ridge too. That's not the concerning part...the other rotor appears to have a raised bump on it!  The picture make it look like a pimple! Very odd and strange! NOTE: These are the factory brakes and rotors.   I'm attaching pictures of the front brakes and what they look like ate ~69000 miles.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      2024 Chevrolet 2500 HD Custom 6.6 Gas Canadian built Truck  I tried to search for my previous thread on this topic but cant find it so my apoligies  for starting another one    #1   Since we have owned our truck purchased new it has this strange noise after using the remote start function  you press the remote start and you hear it start but right at the end of it starting it almost seems like it wants to start again after the truck is running .   There is no gap in time it is right at the end of the start . Almost sounds like when you have started a car/truck and its running and then you try and start it again and you get that grinding noise ,sort of     #2  You can only hear this if you are standing outside of the truck and near the truck  you cant hear it when you start the truck from inside  the cab . So it may very well be happening when starting the truck that way as in normally    #3   This only happens when it is started after sitting . For how long I don't know but it happens after sitting overnight for sure and it wont do it if you stop the engine after starting and then start it again  I have had it in to the Dealership before concerning this but they did not have the truck  when it was cold to hear it . Now its back in the Dealership left it overnight so they could possibly hear the problem . They said they tried and nothing happened . Well they did not know what they were listening for . I started the truck remotely and BINGO it makes the noise . Oh that sounds weird they say . We need to look into it ! I have left for this week at the Dealership    Does your 2024 2500 HD gas do this ?  Any of you fellas care to take the time and trouble to film this operation from a cold start  so I can hear what your sound like  Really  would like to know if this is anormal sound  Thank You Fellas !!

      2026 Z71 Forward and Rear Park Assist help

      By Slow · Posted

      2026 Z71.  The other day I was backing a trailer into the barn.  The alarm was going off just because the trailer was in the field of the warning sensors when you get too close to something.  For some reason now the warning alarm doesn't work anymore.  It used to go off when I was just normally backing my truck into garage.  I still have the guidelines in the back up camera.  Is there a button or something to push to turn the sound/Alarm on and off?  I have the touch screen in this truck.  There isn't a "P" on the dash except for the parking brake.  I can't find anything in the touch screen under settings or vehicle.  Thank you in advance.
