NF (Nitrous Fuel) The proprietary formulation of NF 1. NF boosts the octane without lead (not like TEL) AND 2. NF has additional formulation which stabilizes the fuel to prevent detonation (pre-ignition) which is associated with higher octane. Efficiency of the engine is delivered because NF promotes anti-misting and slower burning of fuel vapor (inside the combustion chamber) which makes the engine more resistive to detonation (or early combustion). This allows the piston to travel to the proper Top Dead Center (TDC) and fire at the precise timing set for the engine. It prevents damage of the engine. The running is smoother. The engine is cooler and easier to tune. Again, with a more efficient engine, the emission is further reduced. 3. NF is more concentrated so that you use much lower volume is required to treat the same amount of fuel. 4. NF has formulation to treat diesel and gasoline. This will ensure comparatively lower shipping cost. 5. Appearance and odor - Liquid amber liquid with slight sweet odour. 6. BP (deg C): 150 C., Flash Point (deg C): 48 C., Volatiles: >90 %, Specific Gravity: 0.92 g/cm3 @ 15 C.
