old petrol in porsche boxter, not starting?

if you give it a spray of easy start down air intake it will usually start and then run on the old petrol if not and the tank is full you will need to drain it,put some super unleaded into tank with the old makes it fire easier and once its running and warm the old petrol should be fine.if it wont fire on easy start and run as you spray it in then you have another problem
