Physical Properties

Physical Properties

Physical Properties

(OP)
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

RE: Physical Properties

Values I found searching the web:

n-C8 RON/MON: -18/-16
i-C8 (2-2-4 trimethyl pentane) + 3 mL/gal TEL: ON 115; + 6 mL/gal, ON 120.3.
