You would absolutely use 93-octane! All high-end performance cars, such as the Cobra, require the use of 93-octane.
VERY TRUE !!!!!!!!!!!!!!REPCobra10 said:
it's been stated that you can run 87, but a noted 93 is the best way to go for that year Cobra
run the lowest octane that you can, that will not ping. Lower the octane, more power your going to be able to get from your engine, since it will ignite easier. All octane is, is a resistance to ignition, enabling you to run higher compression..
Don't the older Cobras have knock sensors? If so, you could run 87 and when the knock is detected the ECU will cut timing to an safe level. You will lose HP in this scenario.
Go to 93 and the ECU will advance timing until knock is detected and pull it back into a safe zone. You should pick up HP here.

most cars that take "premium" state as such, as 91 is much more available in all parts of the country, compared to 93.
