  • Thoughts on Gasoline?
  • What I do know is that in April of 1940 Nebraska University tested the 9N tractor and rated it at 20.29 draw bar horse power. I have documentation that shows the testing being performed with Mobile 68 octane gasoline. My question is with all the improvements in gasoline since 1940 how does that reflect in draw bar horse power with our old 9N's today?

    Octane rating is basically to control spark knock or pre-ignition so has no bearing on energy produced. I mention it because it is available knowledge.

    I think we need to take a good running 9N and put it on a modern "Dyno" and see what the results are. My guess is that with the improvements in the refining process we may see a performance increase of about 20%.

    I still think the old flat head V-8 would have produced more horse power if it had better pump gas. What do you guys think?

  • I don't know if todays gas is any better. I found the Sunoco dealer in Brighton sells gas with no ethanol. They charge 40 to 50 cents a gallon more per gallon. I do know that with the no ethanol gas my float valve does not get eaten up. If I use ethanol gas I have to put new float valves in the carbs every two years. When I talked to Grand Valley tractor about this I was told that the ethanol is known to eat the material on the valve tip. I now look for all stainless steel float valves and also use the no ethanol gas. My tractors seem to run smoother and have a little more pep. Steve

  • Any pump gas that runs decent in these low compression engines is going to produce about the same horsepower. A few percentage points one way or the other really isn't going to be noticeable when we are talking about a range of 20-25 horsepower.

  • my thoughts are if you can find ethanol free fuel your old tractor will run smoother as in less idle pop or miss fire. trying to run alcohol threw it every thing being equal you need a richer mixture to run smooth

  • I found this as today's rating for gasoline :
    1 gallon of gasoline = 120,476 Btu

    So I think the question is what was the BTU rating in 1939

  • I rather doubt you will find that rating. The BTU was in its infancy then and likely not at that time intended to be connected to the. energy in gasoline.

  • Really?

    The British Thermal Unit of measuring heat energy was in its infancy in the mid 1800s. By the 1890s the data and charts were refined to and represent the figures we have today.

  • Todays gas is laden with ethanol, mtpb, butane, miscellaneous refinery waste products, additives and in some cases even water. Refining progress and gubment slack allowed all of these detrimental actions to occur. Pure gasoline of days gone by was way superior.

  • Typo!
  • The correction is MTBE.

  • A change in compression will increase hp, ie the sherman head. Then higher octane gas is needed to control pre-ignition and engine knock.
    You could add a blower or turbo to increase hp.
    You could also polish ports, add more carburation, but higher octane alone will not do much. Un-Like the chicken and the egg, higher compression came first, then higher octane gas...

  • To change the subject slightly. The chicken came before the egg. I believe the Bible is clear on that. Another question did milk come before the cow, etc? The egg had to be fertilized by a rooster to produce a chick. Just thinking out loud.

  • not so on octane.We took 1 second off the 1/4 mile with Amoco hi test.I could advance the spark 1 notch.I was there 1956 The 36 had dual carbs and hi compression heads.

  • Re: Thoughts on Gasoline?
  • Bingo.

    Changing the gasoline alone produces little or no HP increase but it does allow other modifications that would not be possible otherwise.

  • Re: Thoughts on Gasoline?
  • Wish I had not mentioned octane now, its ruining the conversation. The point Iam trying to get at is the cracking, refining and additives used in gasoline now. In my funny little mind the fact that gasoline is better refined and cleaner would translate into better runner higher performance from our engines.

  • Re: Thoughts on Gasoline?
  • It depends upon how you define performance.

    Modern gasoline will produce no HP increase when used in vintage Ford tractor (or similar) engines, all else remaining constant.

  • Re: Thoughts on Gasoline?
  • My granddad claimed that old lower octane gas was more explosive then the newer higher octane with all the additives. The cleaner running newer versions have additives to keep things cleaner more then anything, not to produce more power.
    The newer cleaner gas may actually have less raw power. It would be a good experiment either way. Man has tried to find a gas additive that increases milage and power for the last 70 years, and many claim they have. AND, you can buy some for $19.95 at most any auto parts store. I do know tha alcohol in gasoline produces less power and gets lower gas milage then ethonol free gas.

  • Increased octane rating will have little to no effect upon HP, all else remaining constant.
