I have a 1980 ZX... and i ran it on Regular unleaded for as long as i've owned it... . and it started pinging...
so... i've started using premium... and have gone through a couple bottles of fuel injection cleaner and the pinging has since gone away.
so.. in short.,.. if you can afford it... use premium!
