Unleaded Gasoline — General Description (Nissan Bluebird T12)

1. Contact first Chapter 15.

2. Do not use Premium Unleaded Gasoline (or reduce the ignition timing) on Turbo or Turbo Executive models; these engines require petrol with a minimum octane rating of 97 RON.

3. Owners should notice (if you believe the manufacturer's complaint), that Super/Super Plus grade unleaded petrol has the appropriate octane ratings. Consult your Nissan dealer directly to determine whether this petrol can be used in Turbo models.

4. Note that turbocharged engines are equipped with reinforced valve seats and can therefore continuously use unleaded gasoline with a sufficiently high octane rating.
