Have posted about NF on the other thread.
One bottle lasts a long time as you just add a shot per tank full (not a full bottle).
Applications- Adding 2ml per litre of fuel will give a 2-RON increase, which equates to approximately one-third of a bottle per tank of fuel.
- For higher horse-power engines, add 3ml per litre of fuel to give a 3-RON increase, which equates to approximately half-bottle per tank of fuel.
- For maximum benefit, add 5ml per litre of fuel to increase the octane level by up to 6-RON.
