Data plate restoration

Im not certian but I dont think the resonsible agency plate had been adopted yet in 67-69, however the spot fits the plate as if it was intended to.

That sucks, I looked at my new data plaques and mine also says 68 octane. I wonder how well it will run even if I can find some. I guess I'll have a typo on my truck. Only you guys will know.

Guys, I think 68 octane is about what MOGAS was. However, the data plate on Pistolnut's 10/67 M715 says 85 octane.

So it's not a typo?

My stock plates say 85.....they are definitely original to the truck.

Mine may well have been as well. I'll have to check when I get home.

I just know the manual for my 1952 Gasser M35 says the minimum octane of MOGAS is 68. MOGAS is what the military called gasoline and that is what the M715 was meant to run on. However, nothing that I can remember in the M715 manuals mentions the lower octane number.

Maybe Beast or somebody else with a M37, M151 or other MOGAS eating vehicle will chime in.

The term Mogas, short for motor gasoline, distinguishes automobile fuel from aviation gasoline, or Avgas.

Any gasoline for use in a passenger car, from the lowest to the highest octane is called Mogas...it isnt octane specific.

I suspect that you'd have to have a very, very low compression engine to run on 68 octane. Ford made a version of the 2N, and 9N tractors to run on Kerosene during WWII when fuel rationing was in effect and they were something like a 6:1 compression ratio.

The Germans, also had very poor fuel during WWII for their aircraft and that is where turbocharging came into general use, as a solution to the poor fuel. You could still develop good power from relatively poor fuel and a lower compression engine with the forced induction.

I saw a GPW and they had a low octaine number also I think it was lie 68 octaine.
