Is Non-Ethanol Gasoline Really Better? Let's find out!



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!

  1. Do you have Alkylatbensin or alkylate gasoline were you live. They say its the most cleanburning fuel for small engines but it cost more and dosent wear out engines as fast as pumpgas. My dad worked in the forrest here in sweden for over 40 years, and when the aspen alkylate gasoline came out, they had to use it, no more pumpgas. He said that chainsaw, and that was all he used, wore out every two years before they changed, and they lasted over 10 years after. Maybe something to make a video about if you havent already.

  2. I didnt see much difference in the carbon build up, but it did look like over a longer term the ethanol guel would cause more build up. Like you said its hard to say on a short term test but there were a few areas, especially on the piston where the ethanol indicated more buildup. Interesting.

  3. There is a very old saying – You never get something for nothing !
    The fact the non-ethanol lasted longer is no surprise – The petrol companies know down to the last drop how much energy they are providing you and how are you can travel per gallon !!

  4. Thanks for the video. I have never had any problems with ethanol fuels in my small engines. I do not drain for winter in my mower (usually use it a few times to mulch leaves down that blow into the yard late in the fall) and my blower gets used frequently just to blow off patio for 30 sec every time I mow in the summer/spring time. weed eater is only thing that goes for 6 months or so without being used, and is an old echo, and usually starts on 2nd or 3rd pull. I use the standard ethanol fuel in my 2019 Dodge Ram as well.

  5. What I notice when I use gas with 10pc ethanol is that my car’s tail pipe is blacker. And when run my finger into the tail piipe there is carbon.

  6. I get better gas mileage with non-oxy gas in my cars ,when I fill them up with it .my small gas motors will start up and run great after a long winter of not running them ,if I leave non-oxy in the tank .the non-oxy has less chemicals in to plug up carbs

  7. Ethanol has been used in cars since the early 80s. Cars are designed with ethanol blended gas in mind. I know that older cars not designed for ethanol blended fuel had problems with metal corrosion and gaskets snd seals being dissolved when it was first introduced.

  8. For people worried about corrosion and damage, the biggest thing is to just use a fuel stabilizer. I bought my house over ten years ago and most of my lawn equipment at the same time. In all that time I have never had any fuel problems, even my snowblower which sits for months and months with the carb full of fuel hasn't had any problems.

  9. This was great to see. In a carburetor, those little orifices get corrosion in them because ethanol is hydroscopic. That’s why so many homeowners can’t figure out why after a month or two their machines won’t start. Ethanol loves to degrade primer bulbs too, it cracks those things in no time. I work on many ethanol related small engine fuel problems. In a vehicle that is driven daily, it’s not an issue, but yard equipment or recreational vehicles it’s problematic.

  10. the main reason there is fear about ethanol in fuel is because the oil companies only sell 90% as much of fuel because the other 10% is ethanol. so they got the marketing companies onto it to sell fear. very few cars are old enough to have seals and gaskets that are effected more by alcohol that gasoline/petrol. in short, the ethanol fear campaign is bullshit. and where i live i can't buy it anymore.

  11. Your carbon buildup could be because of incorrect fueling due to stoich differences. I am sure that on your fuel injected lawnmower you would see the difference since it has an o2 sensor and can correct for it.
    on E85 fuel piston's will come out with very little carbon buildup and will generally clean with wd40 and a quick wipe.

  12. I had a pit bike that u was going to run on E85. Had to change carb jets to get proper air fuel ratio, it was a pain

  13. I have zero issues with the ethanol fuel in my gen sets but I also turn off the gas and let it run dry so it should be out of the carb and fuel lines.

    My only issue is usually my chainsaws. Hard to start on old gas. The cutoff switch cuts the engine doesn't allow to dry. So I think there's a little something to it if it's sitting in the carb long term or the lines long term. I don't notice any extra fouling or carbon.
