Some claim pure gasoline to be the final automotive redpill; it will reduce emissions and increase MPG, preserve fuel system life, and even reduce engine vibration and make an engine run cooler.

Some claim it to be a meme which makes no practical difference and, in the long run, will never be worth the added cost over 10% ethanol gas.

Where does /o/ stand?

ethanolets want to bring back lead poisoning

If you have a car with hardened valve seats and appropriate fuel lines (basically anything built within the last 30 years) and don't let your fuel sit for years, E10 is fine.
Old cars that aren't built for E10 will need modifications or ethanol-free, because E10 will fuck them up.

My 2019 equinox has a bunch of warnings about using any gas that has ethanol in it

I pay about 40c more per gallon for 93 non-ethanol vs 93 with e15. Idles better and starts easier, also got like 3mpg more. Since I barely fill up more than 10 gallons, it's $4 extra a tank and I get like 27mpg. Not exactly a financial gain but I do enjoy the way it drives and can tell the difference. Subtle but it's there.

>>28472496
ANY amount of gas, or greater than 20%?

>>28472232 (OP)
>increase MPG
Obviously, ethanol is less energy dense than pure gasoline.
>added cost over 10% ethanol gas
pure gasoline is cheaper to produce.

My car is flex fuel ford tough and the corn oil is half the price. Fuck your oil barons

>>28472636
I think it says to avoid ethanol entirely but I guess I could go check later

>>28472232 (OP)
Also, "low sulfur diesel fuel" is pure bullshit.

>>28472661
Dude it's a fucking Equinox. I pretty much guarantee you it's a "No E15 or greater" sticker.

>>28472240
>Old cars that aren't built for E10 will need modifications or ethanol-free, because E10 will fuck them up.
I don't know why you're out here being an actual retard nigger when you could in fact, just not. Ethanol didn't get added to the fuel until 2007. So literally anything on the road from model year 2006 and down, obviously there's a lot of those, they're all running fine with zero modifications to the fuel system to accommodate the ethanol. One of them being my 1989 corvette. Another being my 2003 sportster. I don't know why you midwit rat bastard fucking idiots want to come on the internet and act like you know something when you really need to just shut the fuck up. The internet gave everyone a voice but unfortunately did not come with a reminder that if you're not legitimately an expert you might as well just stop talking. God I hate you people.

>>28472695
Most based post on the board currently. I think a bunch of these glue-sniffers just caught caught up in the 2021/2022 "hype" of fags like the JRE podcast bitching about the winter blend of gas having a slightly increased ethanol percentage, and now it's some huge boogeyman to them despite knowing nothing about engines.

>>28472695
I don't know where you're getting "anything from before 2007 will fucking die if you try to run it on E10" out of my post, I even said "basically anything built within the last 30 years" as I know most manufacturers were already making stuff that has zero issues running ethanol blends at least as far back as the 1990s.

>alcohol fuel
:)
>alcohol fuel, corn
:(

My country is pushing for e20, but my vehicles are rated for e10, how worried should I be?

>>28472240
>Old cars that aren't built for E10 will need modifications or ethanol-free, because E10 will fuck them up.
This is boomer fudlore. The only negative impact ethanol has on old cars is more frequent carb gumming. You won't hurt an old engine on ethanol. The extra valvetrain wear comes from the reduced lubricity of not having lead in the gas, and even that is extremely overblown. I always put hardend valve guides and seats in old rebuilds if they need it, but more often than not, valves and guides are completely fine despite being run on unleaded gas with no additives for the last 30 years.

>>28472828
Use a fuel stabilizer if the car is going to sit for three weeks or more. That's about it.

>>28472828
Considering most cars can be made to run just fine on E85 if you fuck with the fuel injection quantity somehow (or add a kit to auto-adjust it based on a sensor in the fuel line), E20 is probably fine.

>>28472240
>>28472819
Stop pretending you know what you're talking about and fuck off back to plebbit you retarded cocksucking niggerfaggot

>>28472819
My cars from 2005 and says not to run blends greater than e10.

>>28472840
people forget cars built in the 1920s were literally designed to run on stuff like naptha/lighter fluid and moonshine.

Quit responding to the retard that's never touched a wrench in his life

No eth gives you more stability in the sense that unless you test every time you pull from a pump you dont actually know the exact eth content of the fuel or its water contamination. "E10" could be 4 or 7 or 12%. The station tanks could be water contaminated to some amount and with how this country has been going it wouldnt surprise me if nearly no gas stations have tank cleaning services for multiple years.

So I tune a car, go through a lot of expense and hassle and time to dial in the vvts and spark and wideband AFRs and whatnot. Some random day 8 months from then for whatever reason I get gas at a different station. If I dont know that gas is 11% eth and 1.5% water contaminated compared to 8% and 0.5% suddenly my tune is shit and the ECU pulls fast knock and holds long knock...problems that could still exist, but be considerably lesser if stations didn't have eth at all.

Does it matter for the vast majority? Actually not at all.

>>28472873
If you don't help teach uneducated wrenchlets, they stay unedcuated wrenchlets. Don't be such a hostile faggot.
>>28472872
Pretty much. Big, low compression engines are extraordinarily forgiving with their fuel quality. Unless a particular engine was built out of potmetal junk or is extremely hopped up, it's (anecdotally) rare to see a wrecked valvetrain due to just using modern fuel. Mostly all sloppy old valvetrains I've fixed have been in engines that were obviously otherwise abused or had neglected oil changes.

>>28472840
By old cars we don't really mean cars 100+ years old anon.
We mean 1960s onward.
And yes E10 fuel fucks with those cars.
I had to replace a 1964 C10 fuel system with ethanol rated lines, fuel pump, and carb gaskets.
E10 will absolutely kill older engines even if they are driven a lot.

>>28473010
You're right, I didn't mention non-ethanol rated fuel pumps and lines, but the point I was focusing on was that ethanol fuel isn't really going to hurt anything once it's in your intake. You won't burn up any valves or seats exclusively due to using E10.
>E10 will absolutely kill older engines even if they are driven a lot.
This still is still wrong. It can gum up and hurt original rubber components in some fuel systems, sure, but is almost definitely not going to harm the valvetrain. Even a lot of non-ethanol rated rubber is decently resilient and will hold up fine to it for the rest of the life of the line. It'll speed up the breakdown of the rubber, but you should be replacing rubber fuel lines and paper carb gaskets if they're 30 years old anyways.

I'd say the only cars I've come across that really, really do not like ethanol as a rule are anything with early mechanical injection. K-Jet especially seems to gum up pretty badly, pretty quickly in my experience. Mostly anything else will be fine unless your rubber fuel stuff is junk.

This but unironically, or perhaps ironically

Only way to kick those saudi ass is to use home made ethanol

Only way to make power is to have high compression

High compression needs octane

Ethanol has 100+ octane

If you still use gasoline, your saudis' bitch

>>28472232 (OP)
I recently moved states and first fill with the local 87 mix my 1994 shitbox s10 started having starting issues. I suspect there was already gumming in the throttle body injectors or something along those lines…but I’m suspicious enough that I switched to the pure blend gas since then lol

>>28473201
Any good boat stuff you've done recently since you've been at the job about a month or so?

>>28473278
Yeah, been extremely busy working on a lot of badass old Chris Crafts and have a vintage V12 Liberty hydro project in the pipeline. Also been doing a lot of twin engine cigarette boats. I don't want to blogpost much ITT, so I'll probably post some in /ccg/ or /wwg/ when I get the chance.

To stay on topic, all boats generally run ethanol free fuel because water ingress is (obviously) expected, and ethanol is very hygroscopic. It sure isn't cheap though for the on-water convenience. I think our pumps are ~$6.50 for E0 90 octane.

>>28473139
>Clogging every fuel line, Carb Jet, and gasket isn't ruining anything
Anon.....

>>28473313
Cleaning your carbs and replacing 30+ year old non-ethanol rated fuel rubber fuel lines are expected maintenance tasks. No, I wouldn't constitute that as "ruining" anything, especially when the original claim was that ethanol "kills" engines, which is untrue.

>>28472232 (OP)
I have a 20 year old RAV4 I bought brand new, still has the original fuel pump, injectors, and fuel lines. It's only ever seen e10. 202k miles. If you change your oil every 10k you will be doing your timing chain soon and that's a lot more expensive than some fuel line

I don't get it, why have I never seen this no ethanol options out on the east coast?

>>28473377
I'm in the (south) east, and QT has ethanol free in my area. It's pretty much the only one though.

>>28472661

Aright you got me I went and looked

>>28472695
I've dealt with a number of vehicles that had issues with alcohol fuels, but they were all quite old, and the resultant issues were easily rectified.
It was usually the ethanol dissolving the varnish on cork carb floats, or eating up the coating on the fuel pump diaphragm (or check valves).
On any vehicle of reasonably "modern" manufacture, it should be a non-issue.

>>28473377
>I don't get it, why have I never seen this no ethanol options out on the east coast?
they are usually in the mountains or around farmland. people use it for their tractors and other powered equipment.
non-ethanol is extremely common in the appalachians and i'd say every major carrier has at least one non-eth pump in any given town, though it will usually only be one gas station if there are several of the same chain.

>>28473377
Buccees has the option in Texas for boats and such that should be using pure gasoline and not diluted corn juice

>>28473298

Man, remember when e85 was the hip new thing? Damn near every car from ~2009 has some ecofuturist sticker on the driver window boasting about being e85 compatible

>>28473622
I enjoy knowing most people with these, and these type of turbo engines are making shit power because they'll never put 91/93 in them. 275hp? No you're lucky if it's pushing out 250 on a cold day.
I don't enjoy knowing that the used market is full of abused turbo engines that have never seen a drop of high test in their life.
>muh modern knock control
It all adds up over time.

Fuel is ethanol-free where I live (small island) as our fuel comes in by boat. This is not good for ethanol fuels as it would get messed up. No facilities here to blend it either after it arrives, if that is even a thing.

>>28473778
Mine has ethanol free 93.

>>28474038
We've been giving it high-test ever since we bought it, it's expensive, but I suppose not as expensive as the repairs would be if it starts knocking. I find it pretty amusing that overall, despite the better mpg, because it takes the expensive gas, it is barely any cheaper day to day than my early 90s V8 land barge.

I want pure ethanol it's like 115 octane so you can run big comp with alloy heads and good timing. It's over $2 a litre though and only available from race shops.
