Here is my take on things………..

95 RON – not recommended but is ok to use but do not take your car to high revs (above 5.5K) for long periods of time.

97 RON – recommended. Will give a good margin of safety and allow for high revs to be used without pinking. Great every day fuel.

99 RON – the best a safest option of all…. Will give the engine maximum protection against pinking but not needed for every day normal driving however should be used if you are planning on driving very hard ( track days ect).

Remember that there is no real need to go over 6,000 revs……
