Scotty Kilmer how do you get away with skidding up your street?
90% of my engines cant have ethanol, it is bad for carbs and steel gas tanks
Hi Scotty, greetings from a fan here in Brazil... Here we can choose E100 (pure ethanol) or E27(gasoline with 27% ethanol). Sorry for my bad english lol
Hey @scottykilmer I have a question, I’m looking at a 2008 Jeep Compass for my first car. It has the 2.4 4 cylinder and the cvt. Would this be a good car or should I avoid? Thanks Scotty
i got 2012 ford focus and i change with zdetta led dc12-24v with 6000k but when i start the car it lightup for second and turn off and i put back the original bulb it turn on why . is this the battery problem or what and i check my battery with multimeter it show 12.67 v and after start car it gove above 14-17 v can any body help me .
This is a guy who knows how to make videos. No long boring introductions, constantly moving, constantly to the point, always mixing it up with the camera angle so we don't get bored. We're so overstimulated these days that if he slowed down I might just turn on cat videos.
so true
cocaine, it's a hell of a drug
Yes short n' sweet and not long and drawn out like british explanations.
But he's wrong about ethanol. He didn't even mention how bad it is for your engine. Curious. Perhaps he owns corn stock.
My Name is Gladiator >>> If the car’s FLEX, then it’s not bad for the car. If it’s a new computer tuned gasoline engine, then I think its effect is marginally bad. If it’s a carbureted old car, pre-1992, yeah... you have some serious issues that no one wants to talk about.
"And the corn is turned into the ethanol, like this: The corn, goes to a refining plant, where it's turned into barrels of ethanol!" lmfaooo, I died at this explanation, very elaborate 2:01
Me too 😂😂😂
Wasn't being specific Dorks informal
@@floydwalls3537 we all know that, captain obvious. It was just funny nonetheless.
every time you watch him you learn something new, even if you thought there wouldn't be anything new to learn
Meteora125 agree Scotty video had help a lot, and learn a lot from doing it yourself
Truth
I think he forgot the part where ethanol is bad for your engine. This is a well-established fact (intake valves, fuel pump, catalytic converter). It is a really bad substance to burn in your engine. If I ever buy a new car, I'd never run anything but 100% gasoline in it.
@@banno6938 I've watched dozens of his videos. He really does know his stuff. He does mention in another video about what ethanol does in your gas tank that causes problems in your engine but I don't think he thinks it's that bad a problem. Personally, I think consumers should insist that the government stop subsidizing corn producers producing ethanol. This is a total scam. Not to mention how bad it truly is for our engines.
@@mynameisgladiator1933 I accidentally put 85% ethanol in my 2013 cadalac will I'd damage it
Greetings from Brazil, we use a lot of ethanol in here, the only practical problemas are the cold start (won't start in temperatures below 15° celcius, but you can use a start gasoline injector wich makes the job much easier), and the worse gas mileage, but the last one is compensated by the price, and in fact is really cleaner than gasoline, you will notice at your oil change, when you reach the oil mileage change you'll see perfectly the diference, the used oil gets out of the engine much clenaer than the one the ran in a gasoline vehicle... But the power, in a carburated vehicle you can have almost 20% difference in the performance, ethanol can hold more compression rate, that's why it can deliver more power... it's widely used in performance cars in here... thank you Kilmer, keep it up!!!

I'm from Brazil as well, Brazil, Indiana lol. Big farm area, city was named Brazil because at the time Brazil south America was a leader in agriculture. The country even sent us a replica of a famous fountain it still sits in our biggest city park.
o alcool é otimo pra dar potencia.. mas samerda é corrosiva que só, porque tem a soda caustica que faz o alcool não dar tanta pré-ignição.. então tem prós e contras, mas pelo preço que ta por aqui.. o alcool ta sendo melhor mesmo..
Everton Nunes I changed the oil from my car that uses exclusively ethanol and was totally surprised by the color. It was really brown instead of the usual black. Didn't know it was because of the ethanol
Yeah, that's mainly because ethanol has just one molecule, and already has oxygen in his composition (this one oxygen atom is what gives it it's worse gas mileage, you need less air to burn it so you can put more fuel inside de cylinder in each cicle), but the gasoline has many molecules and not all of them burn, that's why the oil in a gasoline vehicle gets more contaminated and turn black, because of these unburned components go to your oil and to the atmosphere in form of polution, the only real bad stuff about ethanol in here that I don't like is the fact that our carburetor need to have a thin layer of nickel to protect against corrosion.... thank's for the repli buddy, have a nice day!!!
I knew you get worse gas mileage with Ethanol, but had no idea it burned cleaner but it makes perfect sense. Thank you Scotty for explaining this I learned something from it.
Not only does it burn cleaner, it also burns cooler (Which is why you're able to get more power. You can advance the engine timing more without getting pre-detonation).
I did not know that either, thanks. I read about it online and you are right.
So why aren't car manufacturers making more flex fuel cars? Wouldn't that solve their emissions problems?
I hard ethanol is like firewood, it cleans the planet to make it, but it smokes worse when you use it. In the end the planet is cleaner, but your street chokes anyway.... With ethanol its only about green house gasses, it makes more greenhouse gasses per distance, but the planet was cleaned - got free from it long before you used your car. Hopefully the ethanol smoke does not stay in the street like firewood smoke..... But there is also HHO
In my case my Silverado goes from 355 HP to 380 HP just by switching to Ethanol. I use it as my fun fuel for local trips. I switch to gasoline for longer trips so I don't have to stop at gas stations so much.
Hello Scotty! Great video as always! Thank you!
I'm brazillian, and i would like to contribute with some facts:
- Our regular gasoline currentlly has 27% Ethanol ,making it RON 95 , it costs about 30% more per liter than Ethanol
- Our Ethanol (before it was called Hidrated Alcohol) has 5% water on it. RON 110.
- The majority of our cars can run on any mixture of the fuels and they have a gasoline reservoir fitted under the hood, in case of the water temperature is under 16 C degrees the ECU automatically injects some gasoline when the engine is starting.
- The price x mileage of both is the same, so you can pick the fuel you like most.
- Regarding electronic problems, sometimes people change the fuel on their vehicles and don't drive enough to the ECU make the recognition of the fuel, then the car won't start on the next day because it thinks it's using the other fuel (The A/F ratio gets all crazy).
Brazilian here just to back up your points.
Also, you didn’t mention we have 100% pure ethanol (E-100)
Very informative. I had to laugh when the Busch Administration was crying for our current 10% mix. There just wasn’t enough to be had early on. Funny at the same time you folks were selling it by the tanker load as export. Here’s the kicker, there was a 100% duty on ethanol brought into the US, maybe still is for all I know. Now the worst anti communist keep em poor tariffs were always 50% against Soviets, China Vietnam and the satellites ect. That was in place since Stalin I think.
So you gotta ask yourself why essentially block trade with a country we had no issues with for a product we desperately need in the mid 2000s. Makes you wonder doesn’t it. Here’s the answer. Dollars, it’s just plain money, greed, industry lobbyists and politicians who are whores to them for re-election.
Yeah, but most modern (meaning 2014 or newer) flex cars here in Brazil don't have that extra gasoline tank under the hood to help the car start in the morning. Not exactly how's technically done, but it works. :)
Slicerwizard he meant that Ethanol is cheaper, but gets lower MPG, while Gasoline is more expensive, but gets higher MPG
As a brazilian I can talk a bit more on the subject, from the point of view of someone who does car maintenance:
Yes, cars running ethanol will run cleaner, but Flex fuel cars are basically ethanol cars (higher pressure engines) with ECU adaptations to run gasoline. The result of this is that a Flex car will NOT be as efficient as a pure gasoline car running gasoline, or a ethanol car running on ethanol (yes some cars from the 80-90s here only ran on ethanol).
So, if you want better mileage, or plan on running only on gasoline, buy a gasoline-only vehicle, avoid those Flex models. Also, ethanol may seem cleaner, but if not filtered properly, it WILL clog up your fuel injectors. That's a really common issue in Brazil. That's the main reason Corollas die here. hahaha
Finally, the gasoline you have over there has much, MUCH better quality than ours. Running on non-premium gasoline here will clog your engine with carbon deposits, that's why some drivers prefer using ethanol and ruining their injector on the long therm, but at least a injector can be easily replaced or cleaned (ultra sonic submersive cleaning), while an engine will most likely need to be opened to completely clean the carbon deposits.
So, if you live in north america, there's no real reason to run on ethanol unless you want to sacrifice mileage for a tiny bit of extra power. Your engines won't stop working from the carbon deposits (unless you're running on brazilian gasoline lol).
E85 is where it’s at. Especially for turbocharged cars! You can inject more fuel into your cylinders which helps cool the engine down. Because stoichiometry says that ethanol with still combust at a higher fuel to air ratio than regular petroleum. Also Ethanol, regardless of how much fuel you might be injecting, has some beneficial cooling properties when compared to regular gasoline. E85 is just less volatile in general. Thus less likely to detonate prematurely, and that is aided by coinciding cooler engine temperatures. So there is a less likelihood for engine knock basically. (Knock is bad boys and girls).
All that means to a tuner is that they can run more boost and add more aggressive timing without the increased probability of premature detonations. E85 can help with other sorts of heat related engine damage.
Be careful tho, E85 is less of a lubricant then regular gasoline so I would suggest that you change your oil on a more frequent basis.
Lastly E85 can be quite corrosive to certain types of rubber used in the automotive industry. So if you decide to convert your car to E85 make sure that you replace the compromised fuel lines, couplers and O-rings with a E85 approved variant.
Scotty is like the shop teacher everyone always wants
*Scotty Kilmer the Science Guy :)*
Jonny DIY For all of 3 seconds.
...and a biased one at that. The only negative thing he mentions about Ethanol is it's 20% lower fuel mileage. No mention of hydroscopic (water absorption) effect of it, nor how many acres of corn it takes to make the stuff. The EPA must have invaded his thinking. When the government subsidies stop supporting the manufacture of it, guess what the price of Ethanol tainted gas is going to be.
:O
Bill Nye is pretty much dead to me since that awful show. Scotty Kilmer is my new Science Guy!
corn and ethanol production is subsidized by the US government, so 93% of the tax payers are giving 7% cheaper E85. what this does is drive up the price of corn as a food product, which hurts the hispanic population with uses corn extensively as a staple in their diet. the world would be better off if we kept the corn in our bellies and oil in our gas tanks.
Hey Scotty, I'm from Brazil and I have to say, you did some pretty good research on that matter. Here because of the farmers' pressure on ethanol sales and prices, our gasoline is mixed with 27% (!!) of ethanol, while premium gas have anywhere between 20% to 25%. Pure ethanol is also available at any gas station with very atractive prices (and modern cars have decent mileage running on it as well, so it can be worth).
That omnipresence of ethanol dates back from the Petrol Crisis in the 70's I think. The government developed a plan to reduce the dependence on fossil fuels. At that time, cars running exclusively on ethanol were very popular. Today, with the drop of the gasoline prices, there are no cars running ethanol only, most of them are flexfuel while some runs on gasoline and diesel.
P.S.: I've learned lots of stuff with your channel, mainly because I just recently got my driver's license and for newbies like me it can really help.
Hello and thanks for the support!
Hey
I am from Brazil
Scotty, your channel rocks! I already rang that bell. ;)
And yes most Brazilian cars are flex fuel, even the gasoline that is sold here has arround 25% of ethanol on it, so it is reasonable that manufacturers avoid gasoline only engines, as they corrode over time using such fuel.
I wish we had more options, as we are somewhat forced to use a non-pure gasoline, and the ethanol prices can vary quite a lot, depending on the season, due to the plantations producing less, or more.
I had a 2011 Tacoma, and with premium gas (no ethanol) I could get about 100 more km per tank (60mi) than with the cheaper regular gas, which had ethanol. Cost per mile was not much different, despite the higher price for premium. What I liked was the longer distance between fills.
+1 My car 2010 Kizashi does run longer on 98 premium fuel. than fuel with ethanol in it.
I love the scientific voice over “corn goes to the refinery where they turn it into barrels of ethanol”
More like a whiskey still!
I used to work in the ethanol industry. There are a lot of misconceptions about E-85 and the industry as a whole. From the myth that it drives up food prices (it doesn't. If anything, it lowers them.) to the claim that it can damage your engine (it can't).
Some people hear "flexfuel" and think that means their engine is equally capable of using either gas or ethanol. It's more accurate to say that you have a gasoline engine that CAN burn ethanol, although it wasn't designed to run as efficiently on it.
In most non-flexfuel cars, you can usually safely burn up to E-50 without damaging anything. The biggest reasons why you usually can't run straight ethanol is because A) it doesn't compress quite as well gasoline. So there exists a possibility of incomplete/late burning in the cylinder. And B) ethanol burns cooler than gasoline (also can contribute to A) so it can negatively impact your catalytic converter.
I bet this is why my turbo engine runs better on e15 than typical e10. My engine can compress it and it also runs cooler.
It still makes no sense. I'm not even going to go into the damage it can cause long term to your engine. But (at least here in Michigan) it is only about 5% cheaper than reg. gasoline and it gives you 20% worse fuel economy. If you take the gov. subsidies given to this industry (ie taxpayer money), ti would be even mre expensive. And the energy it takes to convert this corn into ethanol at these huge plants, uses much more energy than the traditional oil refineries, so they are not really "saving the planet" as much as they claim. Cars will be going to fully electric at some point down the road, so this is probably a moot point anyways.
@@jeffjackson9679 in the San diego area rn e85 is about 3.50, while gas is 5.70, so even with the worse mileage you still save money
The OEM's (mostly US brands) whose vehicles can use E85 don't promote it at all and most people are not even aware of it, which it's a shame cause we could be saving a lot more petroleum and thus become more energy independent.
I agree
I use it in my work van because it stumbles at low rpm on gas, but we are becoming more energy independent by actually going after more oil. All this huge use of corn drives up the costs of all kinds of food. (animals feed on the corn as well). Takes energy to produce the ethanol as well. It has been shown to be a boondoggle in reality. Your using a ton of energy to create a product that yields less energy, so you have to use more fuel. It has to be subsidized so people will buy it. (its 30 cents per gallon cheaper in florida, which is still not enough to compensate for how much more it burns. I figure it would have to be about 60 cents cheaper at least to break even at current prices.
I love e85. Pretty much find it everywhere in south florida. I noticed with oil changes it's cleaner and the oil lasts longer if you don't have fuel oil dilution. The crankcase smells much cleaner during a change.
What dirección in South Florida???
The Corn goes to a refining plant, where it's turned into barrels of Ethanol! Love you, Scotty. Thanks for yet another awesome vid.
Oversimplification, if our tax money didn't pay for it corn whiskey would not come out of any gas pump.
I don't doubt it's cleaner, but not at this hidden cost.
My old car(3.3L Chrysler V6) runs much better on 100% gasoline.
More power and more than 20% better MPG
I'm thinking of tunning my engine to run it for more power. Corn is horrible for making ethanol but our government is being bribed (er i mean lobbied) to subsidize corn growers.
Lord Garth it's cheaper to produce corn than other crop. Corn can also turned into livestock concentrate feed.
naufal muhammad Grasses would boost output and reduce emissions. phys.org/news/2011-07-corn-grass-ethanol-output-emissions.html
Lord Garth thank you for the information but there is still an issue with the ethanol production we still unable to convert the plant cellulose effectively it's still easier and cheaper to turn corn sugar into ethanol
Lord Garth , how do you tune your own engine like that?
I let the experts do that. :) www.burgertuning.com/jb4_pnp_BMW_performance_tuner.html
If you were a teacher I would never ditch class. Keep these coming Scotty!
I have been running e85 here in michigan for 7 years. Absolutely no problems. HIGHER OCTANE,ENGINE RUNS COOLER DUE TO MORE HEAT GOING OUT EXHAUST, AND IT BURNS CLEANER. BEST OF ALL ITS 1.50$ A GALLON 😍
Love the way you dumb it down for anyone thats watching can understand
because not everyone knows a lot about cars and engines
great videos
thanks a lot
If you do your research and your car was made in the early 2000s or later, it is possible to run E85 even if it is not a flex fuel vehicle. All cars have been equipped with fuel systems that can use E85 at least for the last 20 years. This is because 10% Ethanol has been put in gas for the last 20years, so cars have had to be able to withstand it. The main problem is that E85 requires 25% more volume or your engine will run lean which can damage it. All you need to do is swap the injectors to ones with a 25% higher flow rate. I did this in my 2005 Dodge Neon and it has run perfect now for the last four tanks. And here in California, E85 is $2 per gallon cheaper than gasoline right now!
Am I missing something or does Ethanol make more sense for the environment than mining lithium?
It does...but only if we dont drink it all...xD
David blume would agree
I hated using E85 on my grandmother's HHR Flex Fuel. I was curious about it, plus it was $1.99 a gallons. We took it to Corpus Christi from San Antonio, and I got the worst gas mileage out of it and the performance sucked. Ended up using the whole tank, so on the return trip back to San Antonio, I used regular unleaded gas and HUGE difference. Performance was better and we only used less than half of a tank of gas. Both times were at Valero gas stations. Love the videos Scotty. Keep up the great work.
What? Ethanol almost always makes more or the same HP and gets, at most, a couple less miles to the gallon. You seem to be exaggerating.
Nope. Could of been a bad batch of ethanol, but it was a bad idea to use in the end.
I laughed so damn hard at the ethanol manufacturing segment. I love these videos lol
I worked for the Department of Energy (DOE), any gov. critical vehicles, generators, small engines, etc. always 'only' used Non-Ethanol gasoline (no 10 percent, no 85 percent). A lot of military operations have the same requirement. We had specific fuel pumps for that equipment too. And some cold areas of the world, you won't find Ethanol containing fuel anywhere!
Many stations here sell both E-85 and ethanol free, right along with the 10% ethanol regular gas. Talk about choices!
Scotty here in Brazil i have Nissan March 1.6 16v flexfuel. Same engine used in Nissan Versa note or sedan. You can use 100% ethanol, 100% regular gasoline (added 20% of ethanol) or you can mix. We have here a cold start small tank that you need to fill it up with premium gasoline. Here in the south we choose fill it up with gasoline on cold days on the winter. For the tempareture of 32F its much better use gasoline. The car runs a lot better. But for the summer like today for trips the ethanol provides 4 hp on the engine ( 109 hp with gas and 113 hp with ethanol).

Alcohol? SO I CAN RUN MA 14 INCH LIFTED TRUCK ON MOONSHIENE!?!? YEEE YE SIGN ME UP FELLER!
🤣🤣🍻🍻🍻
I owned a 2005 Taurus about 10 years ago that could run on E85 and every time I put it in the tank I would lose 3MPG. I didn't notice any difference in power but it did use more Fuel. Ethanol is corrosive so the fuel lines have to made out of different materials in a flex fuel car. Back in the 80s I had a 1981 Honda Accord and it would vapor lock on Gasahol ( what they called it then). I spent a ton of money on that car before I discovered changing the gas fixed the problem. Ethanol isn't for older cars.
Greetings from Brazil: we have two pump choices here, the E100 (almost 100% ethanol) and gas (wich actually is E27).
There's no pure gasoline here, no way to buy "E0". Very expensive fuels and pretty easy to get gasoline with solvents and ethanol diluted with water.
One of the issues I have with the Ethanol in the US is that we use food to make it, while Brasil uses what is left from the sugar cane after getting the sugar products out...
Ethanol would be a lot more expensive if we used sugar because we don't produce sugar cane. We are one of the world's biggest producers of corn so it only makes sense to use what we already have too much of
@@trevorwilliams1089 That is correct. My point is that we are using food instead of what has been discarted.
Scotty you look like your getting younger....keep up the good videos....
I changed my fuel lines, and fuel pump to run only E85. But that's just one of the many modifications on my car. Love the videos
you didn't need to change those to run e85, unless you are making big hp
juck huo yea I had to upgrade. I am making big horsepower. Everything has been upgraded except the the actual shell
what kind of car is it?
Thanks for the insight👍🏾. Also, the price per gallon in Houston is about $.50 cheaper for E-85. I'm not sure, but that could offset the advantage of better gas mileage a bit.
yeah I've gotten e85 as cheap as $1.33 here in Michigan. on average its about $1.80 though. all though I actually get about %30-%40 worse gas mileage. like you said the price makes up the difference, when it is cheap I actually save money on fuel by using e85 especially since my car normally takes premium gas.
The unsubsidized price of E85 is about $3.60 /gallon (after the typical costs incurred by any fuel to reach its retail point). Are you getting a better deal? Absolutely. Taxpayers are paying for that deal, however.
In Brazil we started making ethanol cars since 1979. But it was in 1983 when Ford introduced the Renault based CHT 1.6 engine which was known for running better on ethanol than gas, this engine is known to be the best functioning ethanol engine from the early times. These older ethanol powered engines will only run on ethanol, they use a little gas reservoir in the engine bay for the cold starts and that’s it. The first flex fuel engines appeared on the early 2000’s with the Volkswagen Gol Total Flex.
Just a small correction; i belive the first one was the 1978 Fiat 147 “Cachacinha”, not 79.
Lorenzo Bolla de Oliveira The information I have is that they started to be commercialized in July 1979.
Augusto Augustoaal that’s possible as well. Maybe i’m just confusing it with the year they launched the pickup version of the 147. Either that, or it is when they announced it.
Nice presentation Scotty,
The local pump price for regular 87 octane is currently $2.50. E85 is $1.59. I have a flex fuel Yukon. Tank average is about 3 mpg less in town per tank. Performance difference is not noticeable. It also starts just fine in Minnesota year round. Btw: it is an old 2002 with 250,xxx miles now on primarily E85. Oil is still clean upon scheduled changes. However, I do run non ethanol in my seasonal small engines as most fuels nowdays do not keep long.
Better yet is the availability of hybrid vehicles and the release by Toyota and Hyundai of the Fuel cell(hydrogen) production vehicles. Check them out!
Please review them for us Scotty!
Wish this was now haha
My 2015 Sentra would get about 32 mpg combined on regular 10% ethanol fuel. I switched to ethanol free and I now get 35 mpg combined along w. A smoother idle and better acceleration.
I have a lot of his videos in my favorite, it's like maintenance archives.
In Australia we have 91 octane (Standard unleaded) 95 octane (Premium unleaded) and 98 octane as well as the ethanol mix fuel E10 since ethanol makes up 9-10% of the 91 octane fuel and the other 90-91% is 91 octane gas.
My mechanic tells me that the ethanol will fry out engine seals so I use a 50-50 mix of E10 and 95, which saves $.
You really need an engine with a higher compression ratio (15:1) to take advantage of ethanol's higher effective octane rating and the better thermodynamic efficiency that comes along with a higher compression ratio. Lower combustion temperatures of ethanol (vs gasoline) might really reduce the benefit of adding a turbocharger to increase the effective compression ratio.
If I were to buy an E85 vehicle, I would rather go all-in, and have it run only on E85 with higher compression and better efficiency. I can carry around a few bottles of octane booster for those times when E85 isn't available.
what do you mean that lower combustion temp might reduce the benefit of a turbocharger? I agree with everything else you said though.
The higher the exhaust temps, the more efficiently the turbocharger can convert heat energy into mechanical work to spin the compressor side of the turbo. If you are burning a fuel with a lower heat of combustion (ethanol in this case), lower exhaust temperatures means the turbocharger not only has less heat to convert into work, it will also be less efficient at the conversion (Thermodynamic Heat engine efficiency). Adding a turbo just to gain a few percentage points in efficiency may not be worthwhile.
@@jessstuart7495 what is intercooler doing with turbos then?
Your still a big help to this day I wish we could see you more this generation will need you ❤
I love ya Scotty but here's a news flash; I ran 50% e-85 in a 2001 Saturn for 7 years and it worked perfectly! The highest octane you can achieve in regular gasoline is 93 octane I believe: E 85 is 103 to 105 octane. I lose about 10% gas mileage, but I pay between $.50 and $.85 less per gallon here in Michigan. Do the math! It's a no-brainer for me. Not only does it burn cleaner, it burns about 300° cooler, and we know the two things that break down an engine faster than anything is heat and grit from the oil deposits. The book "Alcohol can be a gas" educated me on e-85 years before most people knew what it was. In Brazil they run e-100 and the motor oil never turns black. They have options to burn other things other than ethanol. They export most of their oil now, and since they nationalized their Oil, most of the money goes to help the people of that country and not the greedy oil companies!
Brazilian here, and (almost) everything you said was right!
The only correction i’d like to make is that Petrobras actually helps the greedy currupt politicians just has much has the people...
Hopefully that’ll change soon.
I LOVE ethanol! It, and not EVs, are the FUTURE!
Why do people equate octane level to power? Octane only relates to how fast the fuel burns and the higher compression engines need a higher octane to prevent knocking and pre detonation. Putting higher priced higher octane fuel in an engine built for 87 is like pissing money on the ground.
Hammer0f Thor almost all engines running on Ethanol make higher horsepower ratings. About 2-5 HP more.
Hammer0f Thor
You just educated me on Octane. Thanks
this makes me wanna move to brasil
My experience with my small gasoline powered tools is that if they are going to sit for a long period of time, the ethanol in even a mixture of only 10% ethanol will tend to mess up the carburetor, so when storing a small gasoline powered tool, it's best tun the E10 fuel out of it first. Modern automobiles don't have the same problems for two reason. One is they don't tend to sit for long times without being used. The other is that modern automobiles have fuel injection instead of carburetors
In general, Scotty's information in the video is correct, and the best part is that he has a very good understanding of ethanol fuels. I say this because there are far too many so-called auto experts and science people who don't have a clue. All they do is repeat all of the nonsense lies created by the oil industry to bad mouth ethanol.
Here's the information I would add to the video: The "energy content" of ethanol has nothing to do with why a gasoline-powered vehicle will get less mileage when you use ethanol or an ethanol-gasoline blend. The reason for the mileage loss is because the engine is not optimized to run on ethanol. Even flex-fuel cars are not optimized to run on ethanol, they (the on-board computers) merely have the ability to recognize the difference in the fuel and make an adjustment in the air mixture. However, engines that are optimized to run on ethanol will produce equal or better MPG than the gasoline-optimized engines.
In the video, Scotty says that ethanol contains about 20% less energy. Although energy content is irrelevant (as explained above), the difference in so-called energy content is about 33%, not 20%. Gasoline has 116,000 BTUs, ethanol has 78,000 BTUs (the difference is 38,000 BTUs - 38,000 divided by 116,000 equals 32.7%). But, you also have to take into account thermal efficiency. Gasoline does not burn as efficiently as ethanol, which is why there is so much debris from gasoline (the black soot/pollutants). Gasoline burn efficiency is about 75%, compared to ethanol's near 100%. Therefore the true energy content comparison should be that gasoline has the equivalent of 87,000 BTUs, and ethanol has 78,000 BTUs. The difference is then only about 10%, not 32.7%. William J. Hale, one of the world's top "chemurgists" wrote about this in his various papers, including his book "Prosperity Beckons," which was published in 1936. There were many other studies and experiments done to illustrate this, including the two thousand tests conducted by the U.S. Navy in 1907-08.
And finally, all gasoline-powered vehicles (not just flex fuel vehicles) can use E85. But, if your vehicle is not a flex fuel vehicle and you use too much E85, your vehicle's on-board computer may not recognize the fuel and cause the vehicle to run rough - and the "check engine" light will illuminate. Almost all gasoline-powered vehicles can run fine with blends up to E40 or E50 with no check engine light. In fact, studies have shown that all gasoline-powered vehicles (flex fuel and non-flex fuel) will get their best MPG when using a blend of E30 to E40. This alone proves that BTU rating is irrelevant in internal combustion engines. And, this is why vehicles in Brazil can use E27 with no problems.
Since there are virtually no blender pumps (very few) where you can get E30 to E40, you have to "splash blend" your own mix by pumping in some E85 and then pumping in regular gasoline (E10) to approximate the desired proportions.
I'm happy to provide references for any of the above points, if you're interested.

THE AUTO CHANNEL
The Auto Channel Thank you for the additional information. I am not able to use it (the fuel), but have been interested in hearing about (in proper focuses). Since it would be such a major changeover, could you comment (just briefly) on the environment scenario and possibly the corn-fuel-food land and economic aspects? Also, if it really doesn't matter because if electric changes the program to non-ICU, just say that. BTW, I have suspected that if thorium nuclear reactors are employed (which I believe can and has safely been run and is the current all-around strategy) , that would complete an electric generation and use system. I would believe (ignorant) protesters could impede sensible scenarios.
The Auto Channel you missed the point to the ethanol, it produces more water after the burning the gasoline.
So, it degrades faster the car.
I see it every day here in Brazil, some people only want to use the Ethanol and some just gasoline and is visible the agression the the same car suffer from ethanol.
The use of alcohol is bulhshit propaganda.
Only silly idiots think steam degrades the engine. All hydrocarbon produce hot steam . If engine can withstand smaller amount , it can handle larger amount as long as its hot enough to pump the cylinders out.
Degrading can happen in the fuel lines or aluminium exposed to ethanol.
Wow, thanks for your info.. It made sense to me since I had never been able to see any meaningful MPG differences when running unleaded and 85(compared), in my '07 F-150 5.4 Vortex.
well written. people who hate on e85 are fucking idiots
A good overview! Being a fellow Texan, E85 usually doesn't end up making much sense. I did some experiments with E85 and also the very rare ethanol free gasoline and found that "regular" gas (aka "E10") made the most economic sense (price per mile). But if we lived in a heavily subsidized state where the price of E85 was 20% or more cheaper than gas, E85 would be the way to go. Here in Waco E85 is usually no more than 10 cents cheaper per gallon. Of course I still make the long drive to pick up ethanol free gas for my carbureted lawn stuff.
RIght... ethanol fuel is good if you use it quickly, I drive few miles, so I use Ethanol free as it does not turn to water in the tank. In my F150 V8 I get better mileage, and power.
when I had my Toyota Yaris I was using E85 without any problems. I started running it with low amounts of e85 mixed with regular gas progressively until I was only using e85. the little Yaris had only 65hp and I didn't feel any power reduction. I changed my sparkplugs for 4 electrode under the internet believe that the poor mixtures using e85 gives white deposits on the sparkplugs. I also had my check engine light (code p0171) appear because of the lean mixture of the gasoline/air. it was never a problem. my lambda probe was working good according to my obd2 scanner and the ECU was accommodating to the mixture just nice. It was totally worth it using e85 because here in France it costs half the price as the regular gasoline. I wish my new car was gasoline/flexfuel again
awesome, most people don't know the the o2 sensor can adjust the a/f mixture to a certain extent, so you can mix in a decent amount of e85 without a problem.. just if you put too much the a/f ratio will be lean and throw a code.
The code is only there to alert the performance is out of range. Which means less throttle can be applied with more ethanol such as E85. Half throttle works great but full throttle is out of operation range.
Thumbs up. How can ethanol give the engine more power when it has 20% less power than gasoline?
because it is high octane so you can advance the spark timing and run more boost pressure if your engine has forced induction. ethanol is less energy dense but the air fuel ratio needs to be 30% richer which mean there is about the same or more energy in that air fuel mixture..
Thumbs up.
Here in Cali the highest octane available is 91 so a few of us driving high performance cars will use a 30% E85/70% 91 to boost octane and help Knock Learn Value in our ISF's.
I think after seeing this video I'm meant to run e85. I live in Brazil, Indiana lol.
Here I’m Minnesota it’s weird to see a gas station WITHOUT ethanol. Heck, even crown Vic’s of later years used it!
You forgot to mention the shorter shelf life for E85.
I wouldn't suggest letting any fuel get old
I mean let any fuel stay for some time and you better have either some big balls or small brains to attempt start it with old fuel. Fuel in general is not supposed to be kept for long periods of time.
E85 is about 40 cents cheaper than 87 octane, here in Pennsylvania. My flex fuel vehicle might get about 2 - 3mpg less than when I use regular gas, but I have more power when I use e85.
One thing you forgot to mention.
Maintenance on an E85 vehicle is different from a regular gasoline engine.
My brother had a 2013 Impalla that was a Flexfuel vehicle and when it came down to the oil changes, he could only use synthetic motor oil and the local shop wanted to charge him $95 just for an oil change.
I told him I watch Scotty Kilmer videos and could save him some money and do the oil change myself. 😁
A 2013 Impala shouldn't use anything but full synthetic oil. It's a modern car!
My last Volvo S80 service incl break fluid change added up to $762.
The specific engine oil for that car is around $100 a gallon (on the expensive side) but can be found for half that online. A simple small annual service is still a minimum $200
Addictive_LiquoriCe I believe I had a coworker that had that make and model.
She told me it requires premium fuel and being here in California that can be pretty pricy.
I had a 2004 Toyota Celica GTS 1.8L that requires premium but I didn't sell ot because of that but because I'm almost 6' - 3" and found it to be a pain to get in/out of.
95 for an oil change? mean while in my C6 corvette i only pay about 55-65 dollars in oil. i do the change myself.
GrimReaper1675
Yeah, I think that shop was trying to rip my brother off.
He got rid of the boring Impalla and got a '14 Ram 1500
Joseph Murray NICE MAN! i tried paying a guy to do the oil change on my C6 once and he charged me about 96 dollars too. which is why i was confused. how can an impala just as pricy as a corvette? lol. maintenance in a corvette is simple and cheap until you pay someone else that isn't close to you to do it. luckily for the stuff i can't do i have a family friend that plugs me on labor costs.
Accidently filled up a rental hyundai elantra with e85 while i was in west virginia seemed to run just fine though
I wouldn't recommend it putting e85 on a car is not designed for
Us landscapers just hate ethanol in our outboard power equipment 😥
yeah, it eats up our damn fuel lines.
wolfpackflt670 if not prepped correctly
This looks like a fake account, who makes a youtube channel named Mow Better Lawn Service . Are you a russian bot?? lol
Dave Herrera it was supposed to be my channel to upload lawn care stuff to get some following. Some manufacturers send out equipment to test and review to landscapers here, there is a lawn care community you can look up videos on. I just stopped uploading when summer came since it gets really busy during the season.
Buy a 100% gas.
The percentage of ethanol in E85 varies depending on what part of the country you live in. Here in KS our E85 is actually 70% ethanol.
I accidentally put e85 in my truck I filled it up it ran perfect and it's not a flex fuel
That Guy Have you heard of this thing called diesel you should try it and see what happens😂😂
Fuel lines and gaskets in conventional vehicles aren't tough enough to stand up to the ethanol, which is corrosive to rubber. I wouldn't run E85 in a vehicle not designed for it for that reason.
some cars dont have the yellow caps or stickers letting you know its flex fuel - i didnt know my 2005 Tahoe was flex fuel until i was under it changing my oil i happen to look over at the fuel lines an i noticed it had a flex fuel sensor i ran my Vin an sure enough it was a Flex fuel vehicle
Yeah I accidentally do that all the time too then my non flex fuel car I love it
That Guy >>> I think the word of caution in this example you gave us is- Just because everything seemed fine in the short term, doesn’t mean the same will be said if you keep doing it over the long term. A one time test? Okay, then you got lucky.
I’d sum it up two other ways:
1) “If you think everything is going well, you obviously have no idea what the hell is going on.”
&
2) “Everything was fine... until... it wasn’t.”
In Brazil the "common" gasoline in gas stations has at least 25% ethanol, so if you live here or decide to pay a visit and get a car that runs only on gas, the dealer or the owners manual will recommend that you always use premium gas (which is obviously more expensive). But most of these cars here that run only on gas are imported, most cars manufactured/assembled here to be sold here are mandated by law to be flex.
Personally, if I ever get a car that runs only on gas, I'll get a new ECU and a flex sensor and install a supercharger or turbo if it doesn't have one already, with ethanol you can get power more easily with boost, since it has a lower chance of detonation/knock. Fuel consumption will also be way higher, too, of course.
Wow, now I can share my corn tacos with my car! :D
scotty ,and that's what you said. that here in Brazil we still have for those who use gasoline a percentage of 25% of alcohol per liter of gasoline, stirring a lot in the mix of our cars. hugs.
I recently tried e85 for the first time recently and i was surprised by the significant Cheaper price, and i got just about the same gas mileage on the highway. I have a 2014 Impala Limited with the Lfx 3.6l engine and it loved that 105 octane rating. I think running E85 made really no difference in loss of gas mileage bc i have a performance engine, and i think others who try it end up getting horrible gas mileage bc they have just some tiny 4 banger and adding e85 with its 105 octane does them no good.
I'm not sure this is worth mentioning because it might only be a regional thing but I live in Illinois where you know is a bunch of corn so we have a surplus here I guess you can say. Anyway as far as value goes gasoline and E85 here in Illinois is equal. Just as you said Scotty it burns faster but it is also cheaper so in terms of value it's about the same in terms of efficiency I would say it's not equal. But you finally answered the question I've been striving to find the answer to. I always wonder what was better for my engine actual gasoline or E85 now that I know that 85 is better for my engine and cheaper that's what I'll use thank you Scotty
I've seen some gas stations offer "ethanol-free" gasoline as well as the regular gas that does contain some ethanol. Is there any benefit to this other than maybe better gas milage? Is it better for a car's engine? It costs as much premium but doesn't have quite as high of an octane rating.
Yeah.. Ethanol picks up water. And water inside your engine ain't a very good idea (unless its used for a mixture of coolant but NOT in the tank or injector trip or cylinders or for that matter in the exhaust system). Scotty neglected to mention a huge downside of that stuff. Sunoco and 7/11 does not sell flex in FL.
I have a non flex fuel car that I run e85 on. Stock fuel system and lines, but it's tuned for E85. Performs well, lines and everything are fine.
No way really?
love that detailed explanation of how ethanol is made
Miguel Medina lol yeah I died laughing when he started explaining the process 🤣🤣🤣🤣
Hey Scotty! I live in Brazil, and the price of gasoline has sky rocketed in the past few months! In Southern Brazil it might be really hard to find Ethanol, and most people only use Gasoline. I currently live in São Paulo and I prefere running my flex fuel cars on Ethanol. Btw Gasoline in Brazil is 25% Ethanol out of the pump! Love your videos!
loupipeline Every gas station i know here in POA has at the very least ONE ethanol pump. But you are right most (*IDIOTS!) don’t use it.
*that’s a joke
Not many gas stations had Ethanol pumps in Santa Catarina. I know that for a fact, as I've lived there.
Hey Scotty! Is there any point in alternating between the two constantly? Someone told me that gas lubricates more and ethanol cleans that lubrication, so alternating would have some benefit. What do you think? Keep up the great content!!
Just put a DSX flex fuel kit on my 2014 C7 Vette and it runs great!!
Hey Scotty
I like your vids so much
Keep up 🖒🖒
I've been running E85 in a 2006 F150 for 10 years! No problems!
Hey, just out of curiosity, what motor does it have in it?
so, an E85 car could run pure Ethanol (I believe E98 it's technically called, as a small bit of water gets stuck in the mixture) it would just struggle to start in the cold?
I never noticed it harder to start , even in 20 below
Justin Noker I think the 15% gasoline is really to keep people from drinking it like moonshine.
5Rounds Rapid they put methanol in it so you have problems if you drink it
Yes, any temperature under 17 degrees Celcius a car running on 100% ethanol will have a harder time starting, but here in Brazil, they are equipped with small gasoline reservoirs in the engine bay, and it is used to ease the starting procedure.
It is NOT that bad. Also, i belive it IS called E-100 because that only measures the gasoline to ethanol mix.
5Rounds Rapid no, it is actually to make it easier for starting in the winter without the gasoline reservoirs.
In Brazil, they are using a mix of 20-25% of Ethanol in the gasoline(E25) and the Ethanol sold there is E100, so no gasoline added.
Can you use kerosene in a diesel? Just curious. This is a great video very informative.
Yes it is same as ethanol in a gasoline.
@@EB-dr4dd no it's not the same
What about E15. I use it in my 1992 Merc Grand Marquis and 2006 Lincoln Town car. Works great. Costs less than 87 fuel plus rated 88.
So It wouldn’t hurt to try E85 in my truck with 160k on it? Even if I go back to regular gas afterwords? It’s a 07 Silverado with a yellow gas cap and a flex vehicle.
it won't hurt , you will end up with worse gas mileage though
I switch between the two all the time ('04 Taurus), no problems. E85 is about $.60 cheaper/ gallon in Houston, but pumps are hard to find.
Raymond McGee That's one of the reasons I won't use it. It's marginally cheaper, and gives terrible mileage. Not to mention you have to change your oil due to contamination much sooner. It just costs too much to use.
just experiment with different mixes see what you think. some states have the 10% 20% 30% and the E85 so play around gradually increase see what you think.
Flexfuel not worth it is a government experiment.
Only use E85 in gasoline cars to save money.
Ive been running e85 with 87 in my car thats not meant to run it for 2 years now. I put $15 on regular gas and $5 on e85 and the car runs great
Not in depth at all. How about that fact that it’s only affordable because it’s subsidized by the government, and even then you’ll still end up paying $3k more a year to fill up with the stuff. Also, even though it’s not very popular it still uses a major portion of our corn crops to produce so we could never get to 100% use because there’s not enough corn to do so. The main thing is that the government shouldn’t be picking winners and losers in business, so for that reason it’s unethical.
It’s also not really “cleaner.” It may pollute less from your car, but it takes a lot of energy to convert the corn into E85 so you’re actually polluting a lot at the plant that’s making it. It’s like saying the Tesla is “Zero” emissions while negating the fact that it takes huge amounts of energy to make the batteries and the rest of the car which means lots of emissions.
In Brazil, we have 100E, which is 100% pure ethanol. It is cheaper and cleaner then gasoline, and polutes a lot less too thanks to it being made by sugar cane, which absorbs a lot of the carbon right back.
unlike gas atleast growing the corn take co2 out of the air, and it is a renewable energy source. it also helps to be energy independent.
I wonder if there is even a net energy gain by using ethanol?
It takes 2 gallons of diesel to make 1 gallon of ethanol-makes no sense, except to corn farmers.
You have to run tractors and combines to harvest the corn. then you have to make the corn into mash-and ferment the mash. then you have to distill the mash into alcohol. All of this costs a lot of energy. It makes sense in Brazil, because you can fire the stills with the sugar cane (bagasse). The USA ethanol program actually increases the carbon footprint..a total joke.
In Brazil people can also chose between E92 or gasoline (which is E25, to be honest), but otherwise it works the same as in US, if the car is flex, you can chose either.
I'm glad I found your video. I'm looking into a conversion kit that would presumably allow the car to run on E10 or E85. Its called APE X85. Whats your opinion on that? can a module really retune the car to take ethanol? thanks
Here in Peru there is a big car market for GNV (Natural Gas) and GLP (Petrol Gas), I'm thinking of having one of those systems installed in my gasoline car... a few years ago Gasohol (Gasoline + Alcohol) was introduced to leave pure gasoline behind... According to some sources the mixture now is 7.8% alcohol and 92.2% gasoline.
Welfare-farmers like to be able to buy new $60k pickups every year, and most of them are diesel like their tractors. It's hilarious.
well i bet you're fun at parties.
FISH ON......evidently you have never farmed, but are an expert on the subject. Figures!
Wow. Youre really stupid
Well at least they WORK for their money dip smack
I live in central Ohio and E85 pumps are everywhere. Seeing that map of all the E85 stations across America was shocking to me. I always thought they were just as everywhere as it is whereI live. I still remember when the local price of corn sky rocketed a few years ago.
I love the new style of videos with the effects. Keep it up !
The fuel that is best is the fuel your car was designed to run on... now I don't have to watch this video... but hey, let's see what Scotty has to say...... Great Video Scotty... actually very informative for those who don't know.
Ooooo
e85 = 100 more HP on my protuned sti compared to CA91 octane.
Yes realize some dragsters run on alcohol and they go super fast
got protuned by a shop but you cant just go e85 and expect huge gains. i had to upgrade the entire fuel system to support higher fuel flow. injectors/pump/rails/regulator. the difference from my e85 tune and 91 octane tune is around 100hp.
Ethanol is about 120 octane, so if you can adjust timing for higher compression you get a boost. It also is oxygenated but to get the oxygenated boost you need more fuel flow and you get like 50% lowered mpg.
Thats Boss AF
Half the energy per gallon, but can burn 4 times the fuel per compression stroke., so yes, you can get a huge HP increase. The alcohol needs far less oxygen per gallon to burn.
Ethonal is also hydrophilic. It basically attracts water into the fuel system. If they could make ethonal more powerful, and to use less resources and energy to produce, it would be a better fuel option. Unfortunately, corn ethonal take more energy to produce than what the end product produces. I live in a very wet climate. People have reported having rust inside their engines because ethonal attracts water. So there needs to be a way to take care of that problem. I really do enjoy the videos though. Keep them coming
Scotty, why didn't you mention what alcohol blended fuel does that hurts your engine? For those who are wondering, alcohol blended fuel even 10% blended will ruin your fuel lines and corrode anything aluminum it touches potentially leading to thousands in repair costs. Most newer cars can handle 10% blended without any difference in fuel/air tune but lawn mowers, chainsaws, or anything with a carburetor will need to be tuned richer for 10% blended or you will burn them up. That's if the alcohol doesn't corrode the inside of your carburetor into white powder first.
All that i can say is that we (practically) do not have E-0 gasoline in Brazil, and i’ve never seen that that you mentioned happen.
Maybe it’s a difference betwen Sugar Cane and Corn based Ethanol? I don’t know.
In Brazil every gasoline is 30% ethanol, and we use flex cars that can run on ethanol. But since ethanol is more expensive (per mile), off course people prefer to buy the mixed gasoline.
Very informative video Scotty!
You are not kidding about ethanol burning faster. I had switched because of this fuel price gauging, but now I have to work the numbers to see if I’m actually coming out ahead. Thanks.
I run a e85 Mustang. I make 500HP and I love it

Many mechanics have told me that Ethanol in gasoline is the culprit for varnishing-up carburetors in lawn mowers, generators, weed whackers, e.g. Trying to buy Ethanol-free gas in Texas, when I could find it, was always significantly MORE expensive than the 10%-Ethanol Gasoline.
Just being curious... Does americans use LPG instead of petrol? Here in Europe LPG systems are pretty common and is twice as cheaper than traditional gasoline...
OelOel if by LPG you mean propane gas, we use it mostly for recreational stuff like grilling and cooking in general. Some industries use it to operate forklifts too. It’s very very uncommon to see a car running on LPG here in America. Most of our vehicles are gasoline (petrol)
Thank you, guys
OelOel for last 10 years commercial petrol vehicles has to run on LPG or CNG in India , this reduced a shit ton of nitrogen oxide pollution as most people put a mixture of petroleum and other chemicals that is cheaper but pollute like hell ...... when you get on to road few years ago your eyes will burn but now that's all gone! ;-) , plus some people also switch to LPG gas car as it cheaper than petrol.........
We don't really use it for cars, mostly for cooking. Natural gas is used by public buses. For example here in Texas, gasoline is US$2.20/gal (US$0.58/L; €0.47/L; £0.41/L)
Wow that's dirt cheap. Here in Germany you pay about 1.32€/L (E5) or 1.30€/L (E10).... most of that is tax.
Here in Australia we can use E10 which is 10% ethanol and most new cars can run on it. Price is only several cents cheaper than regular fuel.
Big problem at the moment is that unleaded petrol is close to $2 per litre with some places selling for $2.20 and that's with the government temporarily removing the fuel tax until September. The Russian invasion of Ukraine has put the barrel price up which is the main reason behind this increase.
We are looking at prices of $2.50 per litre for regular petrol(gasoline) in September 2022 if things continue the way they are.
Ethanol is stupid because it costs so much energy to produce from corn than gas and returns less energy. It's a net energy loss according to my Prof of Chemical Engineering back in the day. Coal power is used to produce it resulting in a net higher pollution than gas as well! The sugar cane ethanol may make more sense, but imports of that are banned to the US. That's the tell right there on what it's really about. Ethanol is just a subsidy for farmers. It's a government hand out combined with false propaganda about it being clean and renewable. Fake.
Joe M. Far from the truth today
Well, as of 2015, apparently you have to put in 1 BTU for every 2 BTU returned. I don't know what gas is but it's much less. Mind you, you get way worse gas mileage with Ethanol on top of that. Hence, it uses more energy than gas per mile. Net loss vs. gas. Most US ethanol is sold because of government mandate and ban on imports.
Joe M. I agree. Besides, corn is food and does not belong in your engine. On top it uses huge amounts of water. And as we all know, there are many substitutes for oil, but there are no substitute for water.
Yep. I remember one of the idiot politicians (I think he was from Iowa) was proclaiming cars would get better performance and fuel economy with E85, which is complete bullshit. Unless you have a high performance engine the octane boost will not benefit the engine over reg. gas, and E85 gets around 20% worse fuel economy than reg. gas.
Not to mention that corn is food
My 2021 f150 is flex fuel, it will also have hands free assisted driving enabled in about 3 months from now.
