I have always run unleaded regurlar 87 octane in my 1978 280Z and in my 1979 810. They don't ping, they always pass the emissions test on the first attempt and I've had no octane related problems. The HP rating for my 78 is 170HP/5600RPM (sae). The tag should be located on your left shock tower unless someone removed it.
