• 2-stroke motorcycles

• ATV racing

• MX and dirt track

• Kart and shifter kart racing

• Micro Sprint racing

• Personal watercraft racing

Fuel Compatibility

BeNOL mixes with a variety of racing fuels, including:

• Gasoline

• E-85

• Methanol

• Ethanol/alcohol

• Nitromethane

The formulation stays in suspension above approximately 35°F. Castor oil can separate from fuel at lower temperatures, so BeNOL is not recommended for extremely cold conditions.

Recommended Mixing Ratios

Typical Klotz recommendations include:

• MX/Dirt Track: 20:1–32:1 for air-cooled engines; 32:1–40:1 for larger water-cooled engines

• ATV: 20:1–32:1 air-cooled; 32:1–50:1 water-cooled

• Kart: 16:1–20:1

• Shifter Kart: 32:1

• PWC: 40:1

• R/C Glow Engines: 15–18%

Always follow the engine manufacturer's or engine builder's recommended oil-to-fuel ratio.

Important Application Information

Klotz BeNOL is a premix racing oil and is NOT intended for oil-injection systems. It is formulated for applications where the oil is mixed directly with the fuel.

BeNOL is also not recommended for use in ambient temperatures below approximately 35°F because castor oil can separate from fuel in cold conditions. It will blend with gasoline, E-85 and alcohol-based fuels at appropriate ratios.
