I have just purchased a 2004 Nissan March 12SR. Could you please tell me the best fuel octane to use? Many thanks

The 2004 Nissan March 12SR fitted with the CR12DE engine runs on high octane fuel (95).

Thank you Donavan. The car is currently running on 91 (as supplied by the car dealership). Will that be detrimental to the engine?

One tank shouldn't be a problem.
