We are getting ethanol free gas in our town next month, is it safe to run? I know lawn mowers and everything is no problem but not sure about my truck.

Side note, checked my owners manual it says - Use only unleaded gasoline or unleaded gasoline blended with a maximum of 15%

So my take on that is you can run ethanol free in the 6.2.

 

You can run ethanol free or ethanol it makes no difference, I'm thinking that your truck is Flex Fuel so it can run E85 unless something has changed.

It's got the yellow cap, I don't have E85 in my area.

 

Unless you run around empty you don't want to use it anyway.

Thanks for the info Denny, maybe I will see a jump in mpg with ethanol free even 1 mpg would be good to see haha

 

I've run both ethanol free and E10 and I can tell no difference in mileage or performance.

Denny

 

ethanol free ... is Normal Standard Gasoline since unleaded started.. AKA 1977...

the 6.2L can run standard gas
the 6.2L can run ethanol at 10 percent

and you can run E85...

but at almost 7,000 pounds and a front end aerodynamically like a house... do not expect any better gas mileage.. and in the E85 case LESS mpg.

 

E85 is just junk from what I can tell. I am sure I wont see much of a change but maybe on ethanol free.

 

E15? Take a look at this, particularly if your vehicle is pre-2012:

An extra 5% ethanol isn't going to kill anything. Or shouldn't, anyway

Funny story: Here on Long Island a few years back, marine shops were all busting out with warranteed outboard engines. Lots of failures to the point that the manufacturers started to look into it because they were losing money hand-over-fist.

Turns out, the local gas stations here were selling what they said was E10 - but in fact, it had much higher ethanol content - some as much as 20% or more.

Now, we're talking very high performance 2-stroke outboard engines, not Ford V8's.

At the time, all the gas pumps had stickers on them that said something to the affect of "Contains at least 10% ethanol". Soon after the commotion, without anything in the news showing up, many of the stickers had the "at least" cut out - some pumps around here still have the cut-out stickers on them. Gotta get a pic one of these days.

 

Few years back I filled up with some E20 in Oklahoma (my V10) both in the main tank and aux tank and everything worked just fine with maybe a little less mileage. But when pulling a trailer it could be a lot of things that change the mileage over just one fill up.

the only thing using E15 and E20.. less mileage and on older vehicles is the rubber parts/hoses... over time will soften and eat it...

it will NOT eat aluminum, iron, steel, children, pets ....

100 percent ethanol.. and 200 miles per hour.... since 2007....

 

Pure gas is fine just so you meet the minimum octane requirement for the truck. If you can afford the extra cost with pure gas then run it all the time. Ethanol is crap IMO and experience and it is just another thing the government should have stayed the hell out of.

 

You are 100% correct. Growing corn for one crop a year to get ethanol out of it for fuel use makes no economic sense, due to the fact that corn doesn't have anywhere the sugar content of sugar cane. This is why the government subsidizes it....because lobbyists convinced congressmen that it was a good idea. It isn't.

In Brazil, for example, they get 3 crops per year of sugar cane. Basically grows year round. Then it makes economic sense to take all that sugar, ferment it, and make ethanol out of it for fuel use. Most cars in Brazil run on E85 blend, because it's cheap.

Alcohol still has a lower BTU content than gasoline, because it has less carbon-carbon bonds in it than octane. Still works as a fuel, just not that great mileage. Problem with ethanol is that it absorbs water naturally from the air, since it can mix with water freely, just like your vodka or whiskey.

Anyway...don't get me started...

 

It attracts water as in "hygroscopic". Not good for small engines, not good for fiberglass tanks. Doesn't store well. What's not to like? ha ha.

The farm subsidies are basically gone btw and have been for several years now. At least, the direct payments anyway as I understand it, and paying people not to grow crops. That's what everybody wanted, right?? So now some are bitching about the high price of corn? Make up your mind!

Now this is something people need to understand, I'm not a production agriculture guy or a farmer, but I can read. Corn was (at times) $2 a bushel in this decade, and the one before that.

Oh, and in the 1990s, 1980s, 1970s, 1960s. And the 1950s. Be careful what you ask for is all I'm sayin'. Can you think of other commodities that still cost the same nominal price 60 years later?

Corn is just feed, that hasn't been turned into steaks yet.

The stuff you see in the fields mostly isn't for human consumption and never was (excepting sweet corn and popcorn etc, just tiny crops) it's field corn. Poor people aren't being denied anything, this is just nonsense. The neat thing about ethanol production, stripping the starch out still leaves distillers dried grains to be fed to cattle and hogs, as they were going to be anyway.

It's not an "either or" thing, or diverting food crops or similar arguments. Not saying I put corn squeezins in my rig, but there's a lot of misinformation out there.
