- This is a follow-up video to the John Deere B - Gasoline vs. Kerosene video.
In the first video my experiment yielded everything I wanted except for running temperatures.
This video will focus on operating temperatures on Gasoline vs. Kerosene.
1924 Forsdon F Tractor.

From my experience on our farm with all the tractor that started on gas and ran on kerosene there was a significant difference in power when working we use to run them to temperature by working prior to swapping over
When my dad was a kid in the '30s, he drove a Fordson for a local farmer in dry field conditions. The boss would not let the hands carry matches, so Dad would get the revs up till the exhaust pipe glowed so he could light a cigarette.
That's a really interesting experiment. As you rightly say, be more informative to conduct the same experiment under load as well as an experiment showing how power outputs from the different fuels too. Regards 🇬🇧 🇬🇧
I was part of this question back in the 80's.
In this case early Grey Fergusons.
My neighbour was running his on kerosene and the farmer next door had the identical old tractor he used for yard work but on petrol.
They put them to the test on my neighbours field which whilst not huge (his was a smallholding) had a reasonable slope not plowed in 30+ years with the correct era plows etc.
We also loaded a flat trailer with sandstone blocks and got them to pull up the hill.
Results where pretty much the same, the kerosene seemed to have the edge mid range when working hard, when the plow dug deep going uphill and likewise appeared to have a little more low gear mid range pull on the heavy trailer going uphill.
There, my life is complete, a day of messing around on old tractors in 1981/2 to settle a question between to farmers who had nowt better to do on a Sunday has just hopefully answered a question 40 years later 🤪👍

Wonderful! Thank you Charlie. I enjoyed that story.
A W E S O M E !!!! - Fantastic test and analysis ! Thank you for this indepth test and documenting the results.
Thanks! If kerosene was still dirt cheap, you can bet it would still be the fuel of choice (or distillate) because the tractors run great on the stuff.
FYI; the coolant temperature was about 175° F during the kerosene run. I did not think to check the coolant temp on gasoline.
The optimum water temperature is 180 to 195 F for kerosene fueled engine.
The later model Fordson Major powered by the same type of engine had a guage on the radiator
The first Hybrids started the engine on petrol until it got to temperature and then shut the petrol fuel tap and opened the kero, twist the dizzy to get the timing right and go to work for the day
Hola señor me encontré nuevamente su genial experiencia de diferentes combustibles, y lo he visto nuevamente xq de verdad es muy técnico, y me he puesto a pensar q interesante sería si ud hiciera un nuevo experimento (usar diesel y hacer las mediciones y comparaciones con la gasolina) creo q seria genial ver los resultados de estos dos combustibles tan diferentes 🙋♀️👏tal vez un día nos divierta a su mejor manera
Another nice and informative video. I know the Ford N-series and other brands, they had a different manifold on tractors that ran on kerosene. Also some tractors had radiator shutters to run on kerosene. It would be good to test both the Fordson and the JD for hp differences using gas versus kerosene. And thanks for running these experiments. They're cool.
Yes, hp comparisons would be interesting. Thanks!
Hola señor su experimento es muy disfrutable🙏💗, soy tecnica aeronautica y puedo decir que el kerosene es un gran combustible muy versátil 👌, se usa en los turborreactores x su poder calorifico, y también funciona en un motor diésel, en los motores ciclo otto, funcionan muy bien como usted demostro claramente debe estar en un sistema de admisión caliente,, y creo q en los motores modernos se presentaria el problema de la detonacion debido a q son de mas relación de compresión q los antiguos, en fin es una lastima q se aya casi perdido esa tecnologías muy flexibles🙏🤷♀️ y hoy casi nadie los conoce, excelente trabajo 👏👏👏
Gracias mi amigo!
Great comparison! I’d be curious on which burnt cleaner. As far as carbon buildup on the spark plugs. My guess would be the kerosene because of the hotter burn temperature. Thanks for the video!
Good question. That would be a more difficult test to execute, but maybe someday ...
We had the same plugs in ours after 40 Yrs .
My Pop Had one then he gave it to my dad in about 1970 E27N wasnt much diff on Kero just a little less Power , the Australian heat didn,t bother it 40C it ran on both easily , Pa told me he even would mix Petrol Kero 50/50 after the war when fuel was hard to get , and start on that .
I’d love to own an E27N someday. Thanks for the info!
I gave it away to an old engine machinery group and they did a Full Rebuild and now put it on show at Agg and Show events .
Forgive me, but I still am a little confused on how the carb vaporizes the kerosene so effectively as if it were gasoline. I get that it operates typically in a vacuum and as such the boiling point is lower, but seems to me that with the extreme difference in boiling points between gas and kerosene it should affect something...and I don't see how the temperature of the engine therefore has any affect on the fuel air mixture because even on a warm engine, the air intake into the carb is still outside air temperature...it is not affected by the engine temp. So what am I missing?
Hello Andrew, well, the difference in burning gasoline vs. kerosene on these old tractors simply comes down to the physical temperature of the combustion chamber (cylinder head, block, intake manifold, and intake valves). Try to eliminate the carburetor from the equation. Everything is the same with gas and kerosene until it reaches the engine. If the engine is cold, the kerosene passes through a COLD intake manifold, a COLD cylinder head, and a COLD intake valve before it reaches the COLD combustion chamber. It will still be whatever temperature it was in the carburetor and it won't be hot enough to burn. But, if the kerosene is introduced into a HOT engine, it passes through a HOT intake manifold, a HOT cylinder head, and HOT intake valve and ends up in a HOT combustion chamber. This heats the kerosene mixture enough for it to burn. Remember the kerosene is in "mist" form at this point. It is easily influenced by heat and is quickly heated as it passes through hot surrounding metals and into the combustion chambers. That is why, on these old tractors, you had to start them on gasoline and wait for the engine to physically heat up before switching to kerosene. Make sense?
