- Is non-ethanol gasoline really better for fuel efficiency? What about carbon buildup? In this video I use a generator with electronic fuel injection to measure fuel efficiency, an engine with a see-through cylinder head to observe the combustion process, and an additional small engine to measure carbon buildup. Hope you enjoy the video! I enjoy reading your comments. So, please let me know what you thought of this video, and I look forward to your future video ideas!

I'm a mechanical engineer at Texas A&M. Project farm always makes me smile with his attention to detail, his consistent procedures, honest and unbiased results, and logical/practical methods. What I learn from channels like these is on par with what i get in class. Thank you for your professionalism. Keep it up!
Thank you very much!
Would like to see more trails, but great comment!
This man goes to great lengths in all the tests he performs. Love his videos!!!
He is the definition of a true homemade American scientist how exact in details. Thank you Project Farm.
Couldn't agree more.
As a test engineer I well know that nothing is more instructive than testing something to directly see the outcome. We even learn from our mistakes! I love how thorough you are and how thoughtfully planned your experiments are. This is science for everyone. Thanks!
You are welcome!
Absolutely agree..

Hi. I like your approach very much for the testing. I can share some experience with you, having been an engine test and development engineer for BM from Brasil. Our main task there was adapting the engines for the Brazilian fuel mixture (up to 25% ethanol or even 100% ethanol). Out of all materials, durability, efficiency and wear testing done on my time there, some very nice evidences came out
1 - Up to a certain ammount of ethanol (the 10% you use here) engines are indeed more efficient - ethanol burns very efficiently, unlike the other detonation inhibitors used. But the detergent/cleaning properties ot the ethanol on carbon deposits are not so pronounced.
2 - the more ethanol you add, harder it will be on engine starting at cold weather. That is why North America stuck with the 10% mark. At 15% is hard to start anything below -15C. Since this extreme cold is never found in Brasil, they chose to increase ethanol content, so the cleaning benefits of the alchool are more evident. I tested 25% ethanol engines that, after more than 10k hours of endurance, looked like a 1-3K used pure gasoline engine, when it comes to carbon and slug deposit. The 100% ethanol engines did not built carbon at all.
3 - YES, any rubber that has a particular base material (If memory serves, any fluor-based rubber) WILL degrade VERY rapidly when using ethanol. All manufacturers that habe been to Brail sellin cars KNOW that. We spend pretty much a decade testing and adapting rubbers and metallic parts to resist the corrosion. So... in new engines this will not be an issue. BUT if you use ethanol in a very old engine (like one with a CARBURATOR), you will likely see the rubber degradation, since those engines may not have the enhanced rubber and metallic coating found today.
4 - Ethanol performance as a carbon deposit inhibiter is not as good on 2-stroke engines Since you actually burn a mixture of gasoline and oil, due to the very nature of the cycle.
Hope that helps your quest.
Thanks for the info. Our Govt is making us switch to 20% ethanol on advise of your former President Jair Bolsonaro. So far we are on 10% and this year we will probably go to 15 or 20%. A lot of our old vehicles esp two wheelers are on carburetors. Wonder how this will go.
Excelente explicação
So basically… driving a modern car (built in the last 10-20 years) the local fuel source should be absolutely fine?
It’s almost like the automakers and fuel companies have a picnic on occasion and talk about this…..
@@glutenfreebeerbrian They do! It is not a Picnic, it is a SAE and the AIEE committees regarding automotive fuel and lubricants. They try to push the envelope for these technologies, and align the materials and performance. It has been there for almost 100 years.
There are analogue committees for Aeronautical systems too. The engineering community for Aerospace and Automotive is really active and try to agree on standards and procedures before governments put our unwanted regulations.
Regarding your first observation... Yes, LOCAL manufactured cars will work perfectly with LOCAL fuel and lubricant standards. Problem is when you get import cars, and get new technology fuels and lubricants in older cars. This has to be closely watched.
Ethanol (the subject matter on the original post) reacts to older tech rubber and metallic materials. That is what you need to be aware.
Wow i thought there is only stupid people in Brasil ;
Turns out there are exceptions
Just the work he puts into doing all these experiments is mindblowing!! My friends and I tried 2 and was just glad it was over, same conditions but more people working on the projects! There is so much work as he cuts a LOT out in his presentations! Better Him than us. Just Great work.

Simply one of the best channels on UA-cam. He does what we'd all like to see done, and does it very well. A huge thanks.
Thanks and you are welcome!
Love your videos. Absolutely excellent. The reason the water-ethanol volume was not 30 mL was likely due to partial molal volumes. When two miscible liquids are mixed the total volume does not often equal the sum of the volumes. This is due to packing and molecular attractions ( hydrogen bonding , Vander Waals attractions, etc). I am a research organic chemist but again your work is really great!!
This.
I was hoping someone would point this out!! I’m not an organic chemist but I’ve taken some college courses and know some pharmacology and bio chemistry 😇
I remember we did an experiment where we combine miscible liquids and the teach said something about the molecules getting in btw each other!! 😇
As a Subaru Technician in Australia we find that E10 fuel
Leaves deposits on fuel injectors and eats away at platinum spark plugs a standard plug gap can go from 1.1mm at factory to 3mm in 112,500 km(sometimes within 50,000km) with the electrode being eaten away. The same spark plug type with non ethanol fuel is dirty but not damaged in any way over the same 112,500km . The money saved by using E10 is spent on more costs at you dealership or workshop due to poor quality fuel.
This is a great Channel. Keep up the good work.
Now tell that to the corn growers and their politician/lobby buddies who made sure that there's a market for their product.
Robert Warke that’s about the amount of usage platinum spark plugs wear out anyways. Use iridium if you want longer service life.
Iridium plugs have their own set of issues.
1 being the hight cost, and 2 they have more resistance in them.
How can California sell E0 gasoline again without adding MTBE?
E85 and the ethanol blends are really good for building race cars on the street but other than that I avoid it and try to use regular mid grade. It’s sad half of our gas has Ethanol in it. It calcifies and build up on everything inside the engine, especially if you have a car or truck with a Carburetor. You take apart your Holley Double pumper amd you’ll find blue calcium like deposits all over the secondaries and the bowls

@@ProjectFarm now thats its boating season could you do me and everyone a huge favor and test products used to shock tge fuel system made to decarbon, clean gum and varnish, lines and stabilize. The 3 major brands for boating is yamaha ring free, star tron ring clean, kind of a knock off and techron marine fuel additive. Now it's said these will not only maintain but cause do a deep cleaning with a shock treatment. Pretty much you need to use 2 ounces per gallon, Yamaha recommended 1 gallon for 64 gallons for a longer shock treatment but since your engines are much smaller maybe you can just for 10 ounces to 5 gallons. Please get back to me if you can cause with the shortages in outboard motors this can insanely help if preventing repowering motors cause my damaged motors.
Thank you soo much

@Lucifer Morningstar why are you telling me to shut my mouth
@Lucifer Morningstar I want to do this because it's a super important thing to do to outboards and the products are VERYYT expensive so it's best to know if it works or it's just snake oil
You are a pure genius, the testing methods, your video production are first class.
I worked in a car dealership the ethanol attacks rubber orings and leaves sediment, burns cooler there fire reducing vehicle fuel efficiency by typically by 10 percent.
I also worked as a small engine tech, customers would bring in the outdoor equipment, it loses power, won't start, etc.
I learned ethanol settles and breaks down after 30 days.
I would find white powdery substance or looked like snot, used brakekleen blew it the passages and cleaned the fuel bowl.
Steam the carb then run bread tie in the ports.
Reassemble test and done. Asked the customer if used ethanol? They use ethanol in everything never have a problem.
At the dealership I worked at and my friend another the service advisor ask where do you get your gas or do you use ethanol?
He would tell them try using brand name gas station and switch to regular gas.
Will give you gas card if no difference.
They thanked him.
When gas hut 5 a gallon here I used ethanol I paid the price, my Silverado with tuned 5.3 started losing power going up hills or long inclined felt jerking sensation.
My winter beater Buick and for fun Cadillac the same.
My toy 83 monte with 454 filled up with ethanol as left the station it fell on its face.
My Nova SS with high strung 406 small block pinged horribly.
Live and learn.i know I use it in everything runs fine I bet.
Thank you for the bideo
first, thank you for making these vids. they are very helpful. one place where its easy to see the difference that ethanol makes is in 2 stroke outboards. not only corrosion in the tanks but also the rubber and plastic in the fuel systems are damaged. the real problem happens when the particles make their way thru the crankcase on their way to the cylinders. most shops will have a wall of 2 stroke outboards waiting to be rebuilt. most of the symptoms follow a pattern that you can read loosely based on time and amount of ethanol. I tell anybody who brings me one to work on that if they can afford me working on it then they can afford the better fuel.
Thanks and you are welcome! Thanks for sharing.
Personal experience: Having dealt with various carb issues previously, I've been using strictly non-ethanol 91 in all my small engines, both 2- and 4-cycle, for about four years now - mower, snowblower, power washer, grass trimmer, chain saw, leaf blower, etc. I don't use any fuel stabilizers and have had no carb issues with any piece of equipment since I switched. (mower is 11 years old, snowblower is 27 years old).
Thanks for sharing.
Do you have experience with 2-stroke oil and ethanol? I heard that not all brands of 2-stroke oil likes high % alcohol gas mixtures.
I have noticed powerloss in some small sidevalve engines when using E-mixes. My old redblock volvos are on the other hand loving 50-50% 95octane and E85.
@@secularnevrosis Well, yes. I used to use regular grade fuel with ethanol in everything, 2- and 4-. Used to gum up my old grass trimmer. I contacted Stihl, Honda, etc. manufacturers and asked re using 91 octane non-ethanol, they said no problem. I haven't had any issues using it in 2-stroke, and the leave blower especially gets a lot of use, 12 months, because I use it to blow light snow off walks and cars besides yard work the rest of the year.
This would probably get expensive for car use
That’s such a waste of money but you do you I guess
Thanks for the great video report. I’ve used non-ethanol in my lawn mower & generator for several years now. The gas tanks have no rust or rust developing. Plus carb stays cleaner than before. Your videos are always well planned and unbiased. Your attention to details without using too many words is awesome. Thx again.
You are welcome!
I’m so thankful for the tedious and focused work you do to answer serious questions that make a difference in our lives.👍❤️
I appreciate that!
Your testing is awesome, love how you look at so many angles of testing, unbiased :)
Nice generator, Project Farm has cool toys. 4% better fuel efficiency is exactly as expected: ethanol has ~60% of the heat energy per volume compared to gasoline. So E10 with 10% ethanol has 96% the heat energy of pure gasoline per volume. And ethanol free E0 gas has a much longer shelf life. For all occasional use engines, E0 ethanol free seems a smarter idea.
Great point. Thank you
Would like to add the reason why non ethanol fuel is better for storage in an engine that doesn't see regular use.
Mentioned in the video, ethanol is hydrophilic, it mixes readily with water. Condensation that happens naturally allows some water into a carburetor which can lead to a hard start/no start condition, depending on the ethanol mix, humidity, how long the fuel sits, and other things. Ethanol fuel in a car isn't nearly as harmful to a car than it is to small engines. Modern cars typically use plastic fuel tanks that don't rust and don't have a big float bowl with parts that can rust when exposed to water for long periods of time.
Obviously, if you're consuming all the fuel before it has a chance to sit and be contaminated by water, not an issue, but it's often best to drain the float bowl and block off the fuel into a carb before long term (couple months or so) storage to prevent potential damage and make it easier to start when taken out of storage.
@@Bigggy172 Except Octane is set by grade at the pump E10-E15 at 87 octane is just that 87 octane. They adjust the Gasoline/Ethanol mix to hit the target Octane, so the added Ethanol doesn't ad in detouring detonation. There is also the fact that the Straight gas is 91 Octane, the higher the Octane the less BTU's their are to use. These means that if you can find 87 in straight gasoline, you can see a larger improvement in fuel efficiency. As low octane Gasoline has more BTU's in them.
Here in south Florida, ethanol-free has caught on for boat engines, as most aren’t used daily and it’s always humid. Definitely even better for home lawnmowers (wouldn’t matter as much with a lawn care company’s).
Yes its a nice 420 capable generator...
l like the idea of long term test and to see how the metals hold up on the carbs and tanks, thanks for making these videos, on a side note ive been using cam 2 racing fuel to see if there is a difference with that stuff, so far small engines have been doing well with that sitting in them.
Hi Mustie1, Thank you for checking out the video and thanks for the recommendation on cam 2 racing fuel. I will definitely check it out! You've got an amazing channel that I highly recommend to everyone! Best regards, Todd
You guys are great!

@@scdevon def. agreed
@@ProjectFarm agree I'd like to see some test results on cam 2 as well.cheers
I use ethanol-free gasoline in my lawn mower because there’s less risk of it drawing water from the air. I’ve had problems with carburetor internal corrosion when I’ve left ethanol-containing gasoline in a lawn mower over the winter. But more recently I’ve been completely draining the fuel tank and running the engine until it clears the carburetor, before stowing the lawn mower for winter.
Thanks for the very informative practical test you’ve shared!
You are welcome!
Very informative video, thank you! I learned my lesson last year with my Ariens snow blower up here in Kennebunk, Maine. The carb was drained for the season, refueled with 10% ethanol gas from Sunoco and within one month it gunked up and wouldn't start. Took the carb off, cleaned it out and now only use "ethanol free" gas. Engine has more power and less exhaust fumes. Will neve use regular gas again in small engines. Also, just put my 2016 Mazda Miata away for the Winter, filled the tank with ethanol free gas. Our winters don't end until June around here. Again, great video! Thank you!
Thanks and you are welcome! Thanks for sharing.
Here in Brazil, we oar FLEX cars that can be fueled only with gasoline, ethanol, or a mixture of the two in any proportion.
Ethanol does not create carbon deposits, oil does not darken.
It can create a varnish, all parts must be treated against corrosion.
Ethanol is being used as an additive to replace tetraethyl lead
Where do you find ethanol-free gas for a car? I thought all of Cumberland and York County had to sell the corn gas. I know Bert's in Bath has ethanol free high octane. He's right on Route One drawing in people coming right off the county line from Brunswick and does good business from that.
@@skipads5141 You can get it at the Shell Station on Alfred Rd. In Kennebunk
Good point on the MX5/Miata front. Cheers.
In Alaska ethanol blended fuel at the general pump is banned because it pollutes the waters by corroding seals/lines in marine equipment. To sell any ethanol blend it has to be at a proprietary pump and clearly labeled.
Thank you for the feedback
And AV gas (like 100LL) is pretty easy to get owing to so many private pilots.
Should be that way everywhere. We are having that crap forced on us.
Brazil has 100% ethanol fuel at every pump. A permanent competition with the oil companies. Why aren't their engines falling apart?
Even Henry Ford knew it was the way, it was his fuel of choice. Rockefeller quashed that by pushing prohibition.
Watch Pump (2014): vimeo.com/237643999
They killed an industry with Cash for Clunkers, never forget everyone involved
Excellent! That said my main concern with ethanol use in small engines is the corrosive effect it has on carb parts, etc, as well as causing rubber gaskets etc to fail.
Thanks for watching!
In real world use in South Florida, use of E0 is a good idea if it is used in a boat motor or lawn equipment. The reason is as shown in tests. It will pull water in from the air. And that is where those engines get their corrosion. In an auto, you have a pretty well sealed tank so that unless it sits a lot, you won't get as much moisture in the system.
Now in my truck, the difference in fuels is a little more drastic. A 25% drop in MPG with E-15 vs E0. As mid-grade is 89 octane and E0 is 90 they are close. Price difference is $2.95 for E15 89 vs $3.48 for E0 90/91. 15% difference in fuel cost so it would lose there too to use E15. But if you go to Premium E15 the cost are about the same per gallon and still less MPG. Another advantage I have found is that the use of E15 leads to a sticking fuel pressure regulator while use of E0 does not.
I was using reg unleaded several years ago and I found that ever 2-3 years I was having carb issues and then at Q-Trip came out with e91 which is non ethanol premium and to this day I've had no carb issues and that's been 15 years not only I use it in my mowers but I also use it in the vehicles. Thanks for all your testing and as always be safe 👍
You are welcome! Thanks for the feedback.
QT is great. Here (in Texas) we have them and Buccee's for real gas.
Thanks for all your work putting some great, informative videos together. They have been a lot of help in decision making for me. In regard to ethanol gas issue, I've been driving the same car since before ethanol and can tell you that my milage dropped from 18-19 mpg to 15 when ethanol was added the gas.
You are welcome!
my biggest issue with ethanol is, they use lower oct gas, put 10% corn fuel in it, and charge ya the same price. so your getting cheaper gas but paying the same for it.
Thank you!
You're exactly right. You're paying top dollar for watered down fuel that gives less BTU'S per combustion cycle than real gas. Plus it attracts moisture, corrosion and attacks all the rubber and plastic parts of your fuel system. The only one's who benefit from corn fuel is the government, the farmers and the oil companies. The consumer is getting shafted at the gas pump.
But you are saving the planet!
thats the idea... just another rip off.
The price is not the same, pure gasoline is much more expensive, if gasoline were 50 % alcohol, the price of gas would be $1.00 cheaper per gallon, alcohol does not always have to be made from corn either

Thanks!
Love it... I was waiting for a video like this. Since I make my own non-ethanol, There is an absolute difference when it comes to ethanol-based gas sitting stagnant in a carburetor. My king quad is proof. If I use regular gas, I have to rip the carburetor part after it sits for a minimum of one month because the needle valve, that's made from cheap ass aluminum, is so corroded that it grows and gets stuck in the valleyway. Never once had I experienced a problem since I've been making non-ethanol. I make sure to add a nice splash of amsoil octane boost to bring my octane back up to 87 plus. One note is to make sure that you let the water and gas mixture sit for at least 2 weeks. The cloudiness will subside but it shows small water molecules still suspended in the solution. It's still runs well in engines if it is still cloudy, but something to consider. Thank you, project farm!
Are you still doing this? I would like to try making my own non ethanol since the closest places around me are kind of far.
@@mellifont96 yep... Super simple and works like a charm
I deliver fuel in New York to gas station and when I deliver that 85 It’s always about 2000 gallons to the station so I put it in the same compartment and the seals wear out on my discharge valve because of that I have five of them on my Tanker And it’s always comparment number three that the seals we’ar out on
Great information! Thank you
because the seals are the incorrect compound ......its not rocket science
@@Jordanklawler obviously you don't know shit about tanker trucks. You don't just go to home depot and buy different seals. Everything to do with petroleum distribution is highly standardised. You use the seals that are designed for the valve. They are prob buna n or ptfe which are supposed to be acceptable for use with ethyl alcohol.
That sucks. I hauled fuel for 1.5 years. We primarily top loaded in company bulk plants, but I did some bottom loading in imperial oil terminal. I know they would have kicked me out for 3 days if I spilled a drop, so leaky valve would be a bad deal. We don't really have e85 in Canada thankfully.
Use Viton/PTFE seals. The NBR seals DO NOT like Alcohol. It also destroys some of the older type fuel lines.
I maybe repeat myself but here it comes again: I love what you are doing and making us other better consumer and buyer when it comes to almost everything we have an issue with! We who isnt working in the business and/or are educated in "engineer" stuff! I am a computer guy and me and my friends appreciate this so much! :D

* My 25y/o Tecumseh 8hp Sno-king snowblower runs great. Carb is clean as a whistle inside.
* I did have to replace the Carb however in year 20. Engine was surging noticeably. Why? After 20 years of vibration, the throttle-shaft had worn a slightly oblong shape into the carb body!!
* That enabled extra air to be sucked in, causing the surging.
* The carbs' internals were SPOTLESS however.
* WHY?? Because I NEVER used E-blended gas.
* The ONLY fuel my small-engines see is Top-Tier NO-Ethanol Premium from Shell or Holiday stations.
* I also add a little Seafoam EVERY time, both to the gas, AND engine oil.

Thank you! Expensive generator but worth it to get more precise results.
Excellent video! Meticulous and well thought out and executed testing techniques! Thanks so much!
Good comparison here but one thing i think worth mentioning that takes place in your car and not in these engines is that ethanol blends have a different stoichmetric ratio. Modern cars will use the feed back from the closed loop system to account for the different stoich ratio or in the case of a flex fuel vehicle measure the amount of ethanol in the fuel and then adjust the fuel compensation to account for the correct afr. If you adjust the jet size on your mowers you could run a E85 setup. You will just have to increase the jet size by 30 percent. Awesome channel! Big fan
Thanks!
I always appreciate Project Farm's objectivity. Thanks for taking the time to do the testing.
Thank you
Good job on having quite a controlled test with home garage setup!
With something I learn from a engine research lab, there are some point we can improve test accuracy. First is to use a known-volume container for fuel e.g. 50 cc pipet with a stopwatch to precisely measure volumetric fuel consumption, then you can convert to mass flow rate later. As your setup already have watt meters, that's a good setup to have. Then you can calculate specific energy consumption (SEC)(in g/kWh) for each test which gives you more comparable result. Although, this won't be 'brake specific energy consumption' (BSEC) because there is no engine dynamometer. But this method should significantly improve the fairness result with minor modification to existing test setup.
Will wait for the follow up test video!
Thanks for the feedback.
As always great reviews! And Merry Christmas to you!!!
Thanks! Merry Christmas!
I had always heard that ethanol burned too hot for small engines. I see that isn't necessarily the case now. Thanks for all the work you put into these experiments, I've learned a lot!
You are welcome! Glad to hear!
ethanol does sometimes burn hot but thats only if your running high compression. or nitrous
Small air-cooled engines run hot at idle because of low air flow. Don't let them sit at idle. And NEVER run them at low rpm under load. Don't puts around the yard on your lawn tractor at low rpm in high gear cutting the grass. If the blades are on, run it at max throttle.

I have an old farm truck and my four wheeler, and that is all I use in them since I go a long time without using them. I see that Murphy's at Walmart now carries Non -Ethanol gas so it is a lot easier to find than is used to be. Enjoy your channel!
I put airplane fuel in my snowblower, chainsaw, weed trimmer, and when I put the motorcycle plus lawnmower away for the winter. I don’t like to run my equipment empty because I don’t want the rubber parts and gaskets to dry out. Airplane fuel is good for a year I was told.

@@patrickancona1193 I’ve had the Harley Davidson since new in 1987, and was putting stabil in it like you said with non-ethanol fuel until 5 years ago when a friend of mine told me about airplane fuel. The bike starts up really quick. Cleaner fuel too. Just giving my 2 cents worth.
Started putting non ethanol gas in 1970 C10. Just Started because there's a Murphy hear in my town in Florida with 92 Octane. Have you noticed any extra " fouling " on your plugs?
You have one of the best UA-cam channels out there and I hope you make a bazillion dollars as a result of your efforts. I’ve bought several products and am now using non-ethanol fuel in my small engines because of your testing suggestions. Kudos.
Thanks! Thanks for sharing.
When I’m at the pump, I usually get the cheapest fuel, which ends up being ethanol10. What most people don’t know is that, although you spend less money on the fuel today, you’ll be back at the pump quicker due to a loss of efficiency. The price and efficiency determine if its worth getting the cheaper fuel. Great video!
Thanks! Thanks for the feedback.
Where I am, the cost of non-ethanol gas far exceeds that of blended. If it only cost 4% more, I would use it every time.
E85- $3.80 25-27 gas mileage
E15- $4.60 28-30 gas mileage
E10- $4.80 29-31 gas mileage
E0- $6.09 32-34 gas mileage...
E85 most efficient for my use
Not efficiency the efficiency adds up to be the same less potential energy is in the fuel
Maybe with flex fuel, but with e87 or even e88 the difference should be pretty negligible since it’s only 10 - 15% ethanol. I reckon you usually don’t wait until the engine is literally running on fumes to fill up so you wouldn’t even notice the difference in milage.
Did you ever get around to doing the long term test of ethanol fuel vs non ethanol on plastic and rubber components? It's been about 3 years now.
I was looking for that as well
Ethanol will eat rubber over time.
@@darkdestroyer2837only on old engines not designed to run on E10
I've been told ethanol fuel degrades seals/gaskets quicker. Maybe hoses too.
*edit* I made this comment 1 minute before the end when he said he'd check the effects on plastic and rubber parts. This guy is great!
Thanks for watching!
yes. That is why car companies will say whether their fuel systems are ethanol compatible or not. Here in Australia that can either be E10 or less common E85.
@@ianmontgomery7534 Here in the States I first started seeing E85 about a year ago, it is 88 octane instead of our usual regular which is 87. So sometimes you will see it on a price sign as 88, sometimes as 85, and it confuses people. There are warning signs on the pump telling you not to use it in small engines like mowers and boats.
Because of those warning signs, and a distrust of anything new, a lot of older guys I know from work say they will NEVER put in their vehicle. I sometimes buy it though, because it averages about 30 cents a gallon cheaper than the 87 regular. Especially a few months back when gas was nearing $5 a gallon. I'm a little distrustful of it too though, and I never put it in my truck when I'm close to empty, only when I have a quarter tank or more.
Curious to see that other video now, and whether he will use any of the E85 despite the government warning signs.
@@johns9652 Ummm.... E85 is 105 Octane John. The high-octane rating is why high boost turbo and supercharge builds use E30, to full E85.
@@mountedpatrolman My apologies if I mislabeled something, I was referring to gas that is 88 octane containing 85% gas and 15% ethanol. It has a blue hose instead of normal black, to make sure you see the difference.
I have seen signs where stations have it that label it 85 or 88 almost interchangeably. Perhaps I added the 'E' myself because it was on the pump somewhere. I guess now that I looked it up, I should have properly said E15.
The pool pump motor repair guy approved ! I use N-E gas in my 90hp boat and lawn motors!
! that was good info thanks farm man.
A lot of work goes into these videos! Great info!
Thanks!
Thanks again. As an Amsoil Dealer this video is very educational and I'll be sharing it. I and my Brothers personally have a motor on our boat and many years ago before we started using Amsoil to deal with this issue, we had to have the carburetor rebuilt and cleaned out twice due to ethanol. Not a problem anymore of course.
Thanks and you are welcome! Thanks for sharing!
Outstanding information as always. I always look forward to what ypu are doing next. Many have come to appreciate your work!! Thank you
Much appreciated!
Love this stuff. This is, actually, science in that everything here is testable.
Thanks!
@uncle reeler It's too bad, you don't have a brain to donate.
What an excellent and very thorough video thinking of every detail, keep up the Great work!
Thanks and you are welcome!
Most of my lawn care equipment have two stroke engines. I was constantly tweaking the carburetor to get the engine to run best using 100% gas. I tried a 10% ethanol blended gasoline and my two stroke engines ran perfectly without having to tweak the fuel/air mixture screws all the time. I run my pre-mixed gasoline at 32:1 in everything. I now mix 10% blended ethanol gas at 32:1. My Lawn Boy is 25 years old, so is my Homelite weed trimmer. My Poulan yard blower is over 15 years old. Everything still runs like new.
Thanks for the feedback.
Just found your page and want to say THANK YOU.You have some amazing videos. You are obviously a very smart man.Thank you for sharing your knowledge.
Thank you very much!
Loved how you conducted this test and the transparency of your methods - very well done!
Thank you very much!
If I may, @@ProjectFarm, I do have one criticism for you. Please do time lapses even with any timers active. That is my only complaint. Otherwise great video.
Another good one! Thanks for the information!
You're welcome
WOW - thanks for the great idea of using a drill / socket to start the lawn mower. I was just about to scrap a 90's model Snapper 2-cycle 4hp mower because the recoil starter mechanism bit the dust. Replacements are non available, and I was trying to figure out if I could retrofit a newer pull-start / cup combo. Ran into lack of measurements in most ebay auctions, etc., etc.
You are welcome!
I like the way you did these tests. Very thorough and informative. Well done. I'll watch more of your UA-cams.
Thank you
Great video Todd, I look forward to watching the long term fuel effects on plastic parts experiment video in 6 - 9 months...
Using a drill is great for starting mowers eh!
I use my cordless 18V Makita drill to start my lawnmower. Its SO much easier than that old hurt your shoulder (cuz it takes forever) pull start! lol
Thumbs up! 👍🏼
Awesome! Thank you
If you want to see videos of experiments with small engine parts with ethanol see this channel:

Thanks for the video. In France sp98 is almost 2€/l and E85 is 0,8€/l that's why people use ethanol instead of pure gazoline.
All of my Toyota hybrid owner friends are on 100% e85 without any pb.

Thanks and you are welcome!
I'm astonished how well put together and detailed this is. Keep up the good work and I would like to see a longer term review with identical machines running the different fuels. Well done.
Thank you
I've been watching your videos for about 2 weeks now, time for me to subscribe. Keep up the good work. I like the fact that you're not sponsored by big brands, companies.
Thanks for watching an subscribing! Thanks, will do!
i subscribed after watching the first video what took you so long
Many thanks for this. I can still buy non ethanol fuel and so always do for my 60s air cooled VWs. I really appreciate your uploads. Thanks.
Thanks and you are welcome!
Boy do I love these videos, I’ve been slacking not watching, but started back up
Thanks!
I hope you include aluminum and zinc coated aluminum in the test as that is the source of that white solid crusty aluminum oxide that forms when ethanol sits in the bowl. Also would be a great time to do a fuel storage stabilizer comparison!
Great recommendation!
I was just making a comment on that myself, had a carb with a solid white deposit in the bowl. Good to know it isn't just me!
Love the videos, so thank you. I think overall your work is well done and very interesting.
Thanks much for your honest appraisal of this discussion.

Thank you for the upload. Like the demos that you do. Keep them coming. Ethanol gums up when it sits in the carb.
Thanks, will do!
I liked the water tests!
Ethanol fuel doesn't have as long of a shelf life as it comes from the pump. Some older or cheaply made equipment will not have fuel lines or other components that can hold up to ethanol.
You really know your stuff, buddy. This should be a must for any first semester mechanical engineers. Keep them coming!
Thanks, will do.
Hi, interesting podcast. I would like to see the difference in fuel efficiency for an engine that can advance spark until a knock sensor input to stop detention? Also maybe the effect of an oil cooler allowing the spark to be advanced more without detention?
A couple years back, all my generators, mowers and anything with a carb was running like crap after the winter storage. Someone recommended I run eth free gas, never had issues since. I swear by it, has resolved SO MANY small engine carb issues.
Thanks for the feedback.
Love the fact that you do these videos that we can watch and learn. Some of the videos answers a lot of questions I have always asked my self. Thanks keep it up.
Thank you!!
The level of attention to details in your videos is excellent. I really enjoy these.
Thank you very much!

Hi I live in Australia and I own A BMW 320i its ten years old. I used to use 95 unleaded fuel but as the price of fuel kept rising I thought I would try the ethanol blend, after a year my engine light come on but I couldn't get to a service agent, the car was still working ok. So I changed back to the 95 unleaded fuel and after only two tanks of fuel the engine light was off and the car was running perfectly. I will never use ethanol again, and thanks for your in depth reviews it has confirmed what I suspected.
You are welcome!
Terrific work. We appreciate your payowla free conclusions and testing.
Thanks!
As a small engine mechanic, i can definitely say that yes ethanol is damaging to materials like rubber o-rings and hoses. Besides that it corrodes aluminium, rusts steel, and creates a chalky buildup that ruins carburetors.
Aaaaand..... It has a lower energy so e-10 fuel is roughly 10% less fuel efficient than straight gas and takes roughly 30% more fossil fuels to create.
We would not have ethanol mandates if Iowa was not one of the early presidential primary states
In Europe it is impossible to get gasoline with not at least 5 % ethanol. I was wondering why they made such a law, as the know well, that the production of Ethanol is ruining the rain forests. But i found the answer. :-) It is damaging the materials of the engine. That means shorter car life and more business for the car companies. So Ethanol is bad for the environment, as it shortens the car life, but its good for the companies that produce cars.
@@friedensmal Not sure if this is true or not but I have heard that the ONLY reason why we use ethanol is because of american farmers not having buyers for their corn.
@Rob Elston Ethanol doesn't take any fossil fuels to create IIRC. How does it take 30% more fossil fuels to mix gas 10:1 with ethanol? Does it take more proccessing to make it? I feel like I'm either missing something or you are just making shit up.
@@codemang87 how is the corn planted, crop maintained and harvested?? Magic?
Thank you VERY much Sir for your thorough & objective fuel testing as well as all of your other work. I learn a lot from you! Keep it up please! I'll be sure to leave a note when I have a suggestive test or idea to pass on to you.
Thank you!
Great test thank you for showing us.
Thanks and you are welcome!
Strong work! Thanks!
Since going to ethanol in gasoline, there has been a remarkable increase in the amount of times required to pull off the carburetors of small engines and clean them (compared to non-ethanol). A few years ago, I added 50 mL of each type of gas to a conical-bottom 50 mL Falcon tube and let them evaporate--the non-ethanol gas had no visible residue, but the ethanol gas had a significant amount of brown gummy residue in the bottom of the tube.
You are welcome! Thanks for sharing.
Yup causes a LOT of varnish to plug up the carbs.
@@mrpoquah varnish? Varnish is more or less associated with bad gasoline. Alcohol is associated with more corrosion and fuel line destruction. Most of this is basically due to inferior parts.
Gasoline leaves hard carbon deposits, while ethanol leaves a gooey slime. I prefer to clean the goo from ethanol over hard carbon deposits.
I like your videos. They actually have some real world application unlike most of UA-cam content
Thank you very much!
Loved this video, very interesting and informative. Thank you.
Thanks so much!
I'm a little late watching this video, but thank you for comparing gasolines. It is surprising how much carbon buildup occurs in that amount of time.
You are welcome!
An old one but relevant today.
Thanks Mr Project Farm.

Pros and Cons of E0 vs E10
E0:
+More energy = higher MPG
+No phase separation = long shelf life
-- Costs more
-- Not sold in my state *** (Not once seen it being sold at any pumps in the state, but it is sold at some places)
E10
+Cheaper
+Better "tailpipe" emissions (I'd rather breathe E10 exhaust then E0 exhaust)
+Works as a very good long term engine cleaner
--Corrosive and attracts water
--Not sustainable, also funds monocrop agriculture
--Worse mileage
--Higher volatility can cause vaporlock
Great point!

@@OfficialNakatsuMegami In your dreams. Since ethanol takes almost as much energy to make as it delivers, it has no significant impact on oil imports.
It's only cheaper because you're penalized for using ethanol free fuel. It actually costs more to process ethanol and add it to fuel than it does to process regular gasoline. It's a con all the way around, and not a good one. You could cover every square inch of arable land in this country with corn to produce ethanol, it wouldn't come close to meeting the demand of switching to 100% ethanol fuels. It would barely meet the demand to supply the machinery to harvest and process it. Go ethanol free if given the option, you'll pay a bit more at the pump but less in the long run by filling up less often.
Biggest issue with gasoline storage is probably the butane in gasoline which helps gasoline ignite. over time the Butane outgasses leaving the gasoline depleted of butane. Thus making it harder to start you engine.
WITHOUT A DOUBT! The BEST Compare and Contrast channel on YT! Your time investment in eliminating variables to assure the test run is a legitimate C & C test is fantastic.
Appreciate that!
Nice test. I watch ou videos often. I’ve made many adjustment to things I do based on your tests. I did a similar on gas sets own at te nMarina. The marinas in my area only supply non oxy premium. Do to the moisture condensation condensation. Certain amount of moisture gets into boat gas due to the vents on gas tanks. I had to have the ants pumped to remove this. It pretty common on larger boats. Even if you use the bas a lot I found thr not gas began separation iabout 30 days where non oxy premium lasted er a year with only a very mall amount of accumulated water. No stabilizers worked at all. He marinas do not allow you to bring your own gas
For this reason. Almost every owner had issues over time. I had both carbs rebuilt. Thre was no real corrosion
In them. Even fuel pumps were clean. Changed water separating gas filters nearly every time I went out . TryingI tried several stabilizers. None prevented separation. He non oxy gas seemed un effected. Regular car gas degraded.. I drain my mower every year. N issues. I generally starts with one pull in the spring with fresh gas.
It’s not been rebuilt 120 times but is very old. Uss little but not smoky.. thanks for the interesting videos.
Thanks so much!
Ethanol needs more fuel flow to run stoichiometric (complete combustion with no excess oxygen) compared to gasoline, so E10 needs a slight increase in fuel flow. Of course the EFI engine adjusts for this with the oxygen sensor, but the carburetor on your mower engine doesn't, so technically it was running a LITTLE leaner on E10 than pure gas. That might make a difference in carbon deposits if you ran them for longer, although probably not noticeable for this short test.
"Ethanol gas makes it run hotter" can be fixed if the carburetor jetting is made richer enough to negate the leaning effect of the ethanol gas as compared against straight gasoline. Also the power loss that occurs when using gasohol with some engines,particularly if they were already calibrated on the edge of too lean even with straight gas.
