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.

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...

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.

      OCI, not when but why?

      By Chuck FB · Posted

      The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".
