The octane of the mix is higher than either alone. (Lead has a non linear octane boost on the gas, no-lead has a higher quality stock. The dilution of the lead has low effect, the boost of octane of the no-lead has a high effect). > 3.

I tried some in my car. Seemed to run fine. But my car will eat any gas, so I can't attest to the octane boost part. You could always try them and report to the net ... (20 Moth Balls per tank or so; and don't use the para-dichlorobenzene ones) E.
