all I know is u can't go wrong with pure ethanol free gas. I don't care if my truck is flex fuel. If it's not good for my lawnmower I'm not putting it in a $50k truck. Just my opinion.

Lol, what. You seriously? Are you aware that your $50k truck is designed with the intention of using ethanol gas. Also while the newer trucks run fine on 87 octane, there are multiple threads that show a considerable amount of engine knock is produced while running 87 octane gas. The 6.2 even says on thw owners manual that 91 octane is preferred.

 

Lol you cant compare a carbureted lawnmower to a truck with ECM

The only problem with e85 is that it eats up gaskets and fuel lines after a long time but with the e85 option we have upgraded fuel lines, gaskets, fuel pump. E85 is a ton cleaner for the engine

i agree on the 6.2 to run 91. I already know that. But I run 87 pure gas. Not 87 with up to 10% ethanol like most people. No engine knock on my truck. U must not have pure gas where u live.

You guys dont run 93 in the 6.2? I thought 93 was gm recommended

I'm no environmentalist but from an environmental standpoint ethanol is a nightmare. Without subsidies it would only be used in some racing applications. JMO

Lol ok. We could go on and on about this. I'm not alone on this. I live in Oklahoma and I would say that the majority of people here do not want ethanol in there daily driver.

The mindset of buying "pure" gasoline is the same mindset that people think 93 octane fuel is a higherend/cleaner/fuel compared to 87 octane. Which we all know is not the case. A manufacturer will dictate what type of octane an engine a engine should used based on compression ratio, and the timing the engine was programmed on.

 

A few gasoline distributors got together and started offering pure gasoline and marketing as a "better" and "purer" product. In the end you end up spending more per gas with no real benefit.

 

Your argue to that, "we don't use it in Oklahoma and people don't want it here" doesn't really mean anything. People don't vaccinate their kids, that doesn't make it a correct choice.

that article was typed up by a farmer lol. I'm an oil man. lol like I said this argument can go on and on and it's still going on. Farmers, refiners, oil people all want the EPA to believe them.

you seem pretty ignorant on the topic and borderline trolling.

 

regardless of what you and your "clique" think, E85 runs damn well on my truck and if it's good for my $30,000 truck, it's good for your $50,000 truck....Whatever the hell that means.

Hey "It's a free county." Running E 85 is an option a lot of us enjoy. Others choose not to. Their reasons seem to vary There is a lot of misinformation, ignorance and prejudice about ethanol for sure. I'm a curious guy and had to find out for myself how my truck would respond to E 85. I think I'm open minded but I'll have to admit I was a little reluctant to put this stuff in my brand new truck. As I have previously posted, it made the truck a lot more fun to drive by increasing throttle response and power. Running "alky" is far from a new concept. Other guys choose option "B" and don't run E 85. That's their prerogative and I respect it.

really you dont think i know anything.. well let me tell you.. you can run E85 safely but you will not have more torque and horsepower then pure gas on our trucks.. It does not have as much energy per gallon so there is no way it can make more power then pure gas can.. If you had a vehicle that was designed specifically for E85 that had way higher compression or supercharger or turbo with lots of boost then theoretically yes it could make more horsepower then pure gas but the reality is that flexfuel is designed to run on a range of fuels from pure gas to 85% alcohol 15% gas so its going to be tuned for the lowest octane your going to be putting in there, so because its not optimized for E85 theres no way for our trucks to make more horsepower.. then you still have all the potential issues of the alchohol even if it was optimized in terms of corrosion, absorbing water etc...

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Typically its said and I agree so far that the engine oil drain plug oring is not required to be changed out unless you see some damage happening to the oring as apparently the oring lasts well. The dealer I have been getting a few parts from never even stocked the oring but instead stocked the whole drain plug that comes with a new oring which for the dealer is easier because they just throw in a new drain plug if there was any question about damage on it as well and charge the customer accordingly but again only if it is needed.    Also a hint about the drain plug oring to help it last vs a risk of causing damage to it, after its been removed and wiped off or washed off ( that is a whole other topic about some solvents damaging orings because some solvent types do ) to make sure to relube the oring with a bit of new oil so that it won't "grip" on the sealing surface of the pan and needlessly stress out the oring. Its no different than putting some oil on the sealing ring of the engine oil filter. So I just grabbed a new drain plug to have on hand although more recently bought just the oring as well but as its special it costs half the price of the drain plug ... !   Since you mentioned the hate to be empty handed theme, I am not sure what you have in the way of filter removal tools as I like using the exact sized for the filter steel 1" wide band with side to side swivel handle filter removal tool, and it can be used to snug up the filter without risk of damaging a filter as well ( its probably a lisle brand I have ). The drain plug hex size is 15mm and I always like using a 6 point socket if I have a choice and with this truck I've been using just a 3/8 ratchet that has a fairly long handle. Do you have a funnel that will work to pour oil in as that is definitely the short coming bastard part about the design with that fill port on the valve cover on such an angle that no normal funnel will even work. There are adapters and things on the market that will set into or screw into that fill port, I didn't want to deal with US shipping as that is all I was seeing at the time so caved and bought a Lisle brand multi vehicle fit adapter funnel kit and it really works well but there are much less expensive adapters out there that work in conjunction with an off the shelf funnel that would do the job also. Now that I have it, I like how it works and works so slick with the shape of the Amsoil 1 quart containers I have now switched over to. Whatever you do, have a funnel system of some sort as you will be swearing if you dropped the oil and then realize you have nothing to properly pour new oil in without spilling it all over the engine !.     Other comments, quite a bit of oil flows out down the filter when its cracked loose due to the housing above the filter so let it dribble down the filter until it slacks off flow and then remove the filter to create less possible mess. It seems these engines can sit for quite a while and drip and if you have time let it sit there and drip out of the engine as much as it wants. Also a good time to grease the 9 zerks on the front end, that's my typical practice anyway to grease the suspension and steering each time I change the oil. And remember to reset the oil change minder ( not something I am used to doing with older vehicles and equipment ).

      Correct way to service 2024 l8t allison trans?

      By Aimatdeer · Posted

      I really did not measure what came out. I carefully followed directions to check level after i did the spill and fill and filter change. I used 10 quarts. 9 was not quite enough. My trans temp was about 175 when I checked it. Truck sitting in my driveway very close to level where I always check oil pretty much every time for consistency. My driveway is just ever so slightly downhill to run water to the street.

      Sounds like maybe it's announcing Navigation turns or Alerts (it mutes the music) ? When it mutes again, turn up the volume quickly and see if maybe the navigation volume is really low?
