If all is stock then regular will work fine. However, if the head has been
shaved you might need mid grade or even premium. Set the timing to spec,
yours should be TDC unless you have a recurved dizzy. While driving in 3rd
gear at about 2000 rpm floor the gas petal. This is lower RPM and higher gear
that you would normally use. If you get no pinging then advance the timing
a little and try again. You should get a small amount of pinging under a
lugging condition. If it pings like crazy at stock timing then you need to
go to a higher octane.
