1. Product Introduction & Main Application
Arnico’s P.A.M Gasoline Grade KS4 is a very high-octane fuel with a proprietary formulation based on alkylate and isomerate cuts, designed for use in high-performance racing cars and engines with extremely high compression ratios. By providing a controlled and powerful combustion, KS4 supplies maximum engine power output without the risk of knock or pre-ignition.

3. Features & Benefits
-
Extremely High MON (MON ≥ 90): Tolerates compression ratios of 14:1 and higher without knock, dramatically increasing specific engine power.
-
Optimized Burn Speed: A fast, complete combustion curve that releases all fuel energy in the short power stroke.
-
Engine Protection: Free from any metal impurities and deposit-forming compounds, extending the life of spark plugs, pistons, and valves.
-
Light & Volatile Formulation: Excellent atomization and evaporation for an easy formation of a homogeneous cylinder mixture.
4. Industrial Applications
-
Professional Motorsports: The primary fuel in rally, drag racing, and circuit racing classes.
-
High-Performance Marine Engines: Fuel for high-speed boats and racing jet-skis.
-
Advanced Engine Testing: Use in dyno testing to extract maximum power from prototype engines.
-
Superbike Racing: Fuel supply for 1000cc and MotoGP classes.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This substance is extremely flammable and volatile. Its vapors are explosive, and inhalation is dangerous. The Arnico MSDS must be obtained without fail.
-
Storage Conditions: Store in special metal racing fuel containers under an inert gas blanket, in a completely cool environment, away from any source of ignition, static electricity, and light.
-
Personal Protective Equipment (PPE): The use of fire-retardant (Nomex) gloves and clothing, safety goggles, and anti-spark shoes is mandatory during refueling.
6. Quality Assurance & COA
Arnico KS4 shipments are accompanied by a Certificate of Analysis (COA) and a complete distillation curve.
