It's a start since only 3 types of cars were used.  Half the time when I pumped E30 I got 87 because the blending pumps were turned off after hours!  Wonder if they checked for that too?

 

SAE Update - February 2023 - 2 (nxtbook.com)

 

High Octane Fuel Study | BioEnergy KDF

 

In the study under question the parameters, in part, were LTFT's ability to hold O2 in the second cat to limits and they did even at E30. The other was corrosion and literally anything made since 2001 will handle it.

 

As the other supplied top link shows, hand blending will satisfy the octane requirements of any GDI vehicle requiring 87 Octane.

 

Have a GDI turbo? At 20% with 82 octane base fuel the octane is at or over 93. At 25% the minimum octane is over 95.

I converted my 2018 6.2 over to be able to run E85 a couple months ago.  My first tank I ended up with 8.70 mpg, which was about 20% loss in mileage from premium.  The E85 cost about 20% less than pre

Thats false in a well tuned engine. More ethanol = less stress on modern engines. Higher octane, natural solvency, cleans up the crap deposits remaining from current gasoline formulations.  Ethanol wi

Dodge just announce the new Demon 170 and it reaching 1025hp on E85.  Crazy numbers for a production vehicle.

That's a big leap and could start a new trend in the automotive industry.

What gets me is all those out there that don't like E85.  Nothing wrong with it in anything newer than 2002.  Now I agree not to use in anything other than passenger vehicles.

 

What is mostly wrong with all our ICE vehicles is they run on crappy fuel.  So much could be done to better the environment and make engines last longer if we had a high quality fuel.

Why do you believe we have poor quality fuel.

@customboss and I have run this rabbit to death. There seem to be two parts to this. Perspective is one. That is fuel now is 'better' than it was 50 years ago.

 

The other perspective, which is what customboss an @Black02Silverado are talking about, is based on aromatic content of gasoline and the polymer-based additives required to prevent them from deposit formation short term, gum. Tis the part of fuel that leaves carbon and generates oxides of nitrogen that create acids that deplete oil additives. Aromatics are what gives gasoline it's knock resistant properties so it isn't like they can be removed. 

 

So, the higher the alcohol content the smaller the aromatic and polymer load that is processed during combustion, the cleaner the motor runs both internally and environmentally.

I base it on 40+ years of OEM and independent engine test cell observance, backed with emissions bags, oil analysis, and then engine teardown R&D testing BOTH compression and IC spark engines for deposits formation.  Our fuels HAVE NOT kept up with EGR, DI, aftertreatment, and turbo and supercharging our computer controlled engines.

For the longest time I thought you meant by "fuels' gasoline. You meant something quite different. Boy, do I feel stupid.

Okay so not so stupid. You were speaking about gasoline. :rolleyes: Huff huff, (me catching my breath) :) 

 

As a chemical engineer by craft then you know that saying 'The fuels haven't kept up" is a bit misleading. That is, the statement implies there is something MORE that could be done when pretty much what can be done to the hydrocarbon, has been. Take out the aromatics and there isn't anything left an SI engine will run on. You couldn't even call what is left gasoline. It's a cut of the barrel.

Not misleading anyone and done attempting to explain my points to you. 

 

You just want to see, read, hear yourself on the internet banging a gong with half questions and internet trolling. I am done with entertaining you and your ilk.  "Showing your work" is bloviating about R&D level things you learned on the fly on the internet.  I thought I could engage and trust you.  I was wrong. You are a internet troll and bully.  You also have little expertise to share about oil analysis which is the single most effective tool for the average Joe to see what is going on in near real time in our engines.  

 

Stick with what you know.  Be careful assuming all you currently do.  Find another info source to manipulate I am done.

My assuming I'm wrong is how I let people get their size 12 out of their mouth. Sometimes I actually am. You ever admit you've been wrong, ever? 

 

That's twice now you've resorted to name calling. :nonod: 

 

What do you think you have I need so badly that I would manipulate you for it? :sigh:  Nothing, that's what. 

 

How did I break your trust? By disagreeing with you? Get a grip and take a lollypop on the way out.

All I know is I have never had a problem with fuel/gas. I have fixed some vehicles and lawn equipment for neighbors that left fuel in them and fouled up the carburetor. Same holds true for a few outboards. 

My simple methods of changing fluids, using fuel system cleaners, replacing some parts as needed or before the manual says to has served me well.

No scientific approach.

I see no point or benefit trying to prove I know more than anyone. It's sad to me to see 2 grown men try to prove who's wrong. WHY? 

I won't waste my time.

This type of chest thumping happens on every forum I belong to. Sad IMO.

Put your ego's aside and let people believe what they want. 

 

My opinion like always, you do what makes you happy.

I’ve never had a problem with bad gas. I have one car that gets 1 tank per year. Sometimes I remember stabill. It’s going on 22 years. Only one car had injection cleaning. It’s 12 years old. Didn’t notice any difference. Buy most of my gas locally at my Krogers store with my discount card. It’s not even top tier. On trips I stop at truck stops. Mostly Loves. Always high volume locations.

Then you misunderstand me sir. More or less has nothing to do with this exchange and I am more than happy to be wrong.

 

I'm aware that I can be wrong in two ways. Ignorance, of which I am greatly so; and happy as a clam at high tide when that void is filled by anyone. And secondly error. Something I think know I've adopted because reason and logic and many convincing proofs have assured me of its value. If this error is to be corrected, then it MUST be displaced by the same method it was adopted. Reason, logic, convincing proofs. 

 

Thar requires dialogue and thoughtful presentation, and REASON demands that it withstand the test of CHALLANGE.

 

Dragging out credentials and debasing oneself by name calling only convince me of one's inability to meet that challenge.

 

Labeling that demand as being a Bully is irrational. You know my stance on irrational and unreasonable people. I have little use for those that cannot respect boundaries.  

 

This tread is about Ethanol as a fuel. How about we get back to that?

      New to Me 2010 SLE (Quirks, Issues)

      By davester · Posted

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      New to Me 2010 SLE (Quirks, Issues)

      By fm2176 · Posted

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?

      It's Been a Long Time...

      By fm2176 · Posted

      My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
