Klotz BeNOL 2-Stroke Pre-Mix Castor Oil 1 Quart BC-172 — Race-Grade, Low-Smoke Anti-Wear Formula

Klotz BeNOL Pre-Mix Castor Oil is a race-grade 2-stroke pre-mix lubricant engineered to deliver a strong protective film, reduced smoke, and reliable wear protection for high-output engines.

Built from highly refined castor base stocks and fortified with anti-wear chemistry, Klotz BeNOL (BC-172) is formulated for performance motorcycles, ATVs, karts, and other 2-stroke racing applications. This one-quart premix oil is intended for blending with methanol, ethanol, nitromethane, or gasoline per manufacturer or racing specifications, giving you controlled lubrication that resists scuffing and minimizes deposit buildup under extreme temperatures and RPMs.

How does Klotz BeNOL protect high-revving 2-stroke engines?

BeNOL creates a tenacious lubricating film that reduces metal-to-metal contact even during prolonged high-load operation. The oil is extra fortified and de-gummed to increase film strength and load-carrying capacity over conventional castor oils.

• Double the film strength compared with standard castor oils
• Anti-wear additives that help prevent scuffing and ring wear
• De-gummed formula for consistent lubrication at high temperatures

Will this oil reduce smoke and combustion deposits?

Klotz BeNOL is engineered for a cleaner burn than typical castor blends, reducing visible smoke and helping to limit carbon buildup in the combustion chamber and exhaust. That cleaner combustion supports steadier throttle response and smoother operation under race conditions.

• Clean-burn technology to limit smoke generation
• Formulation aimed at reducing carbon deposits on pistons and rings
• Improved throttle response from reduced combustion residue

What fuels and engines is BeNOL compatible with?

BeNOL mixes readily with methanol, ethanol, nitromethane, and gasoline and is recommended as a premix lubricant for a wide range of off-road and racing 2-stroke machines. It is not formulated for oil-injection systems—use it only as a pre-mix according to engine maker guidelines.

• Compatible with methanol, ethanol, nitromethane, and gasoline blends
• Recommended for Beta, Gas Gas, Honda, Husaberg, Husqvarna, Kawasaki, KTM, Suzuki, Yamaha
• Not suitable for oil injection—use for premix applications only

What premix ratios should I use for different applications?

Klotz provides specific mixing ranges to match cooling types and engine uses, from air-cooled dirt bikes to water-cooled race engines and glow fuel applications. Follow the manufacturer’s recommendation first; use these ranges when no specific guidance exists.

• Air-cooled 2-stroke engines: 20:1 to 32:1
• Water-cooled 2-stroke engines: 32:1 to 50:1
• Racing kart engines: 16:1 to 20:1; 2-stroke glow engines: 15–18%
• 4-stroke glow engine mixing: 5–10%

Who this product is for: Klotz BeNOL Pre-Mix Castor Oil suits racers, performance hobbyists, and mechanics who demand high film strength, controlled combustion, and reliable protection in high-output 2-stroke engines. If you run premix 2-stroke motorcycles, ATVs, karts, micro sprints, or personal watercraft and need a proven castor-based lubricant that balances wear protection with reduced smoke, this quart of BC-172 is formulated for that purpose.
