Physical Properties

[Earl100]

I need 4 octane numbers:

for n-octane, motor octane unleaded
for n-octane, research octane unleaded
for i-octane, motor octane with 3 ml tetraethyl lead per gal
for i-octane, research octane with 3 ml ditto

Yes, I realize we don't use lead in the US anymore.

Thanks,
Ken
