Schaeffer’s 707 Extreme V-Twin Synthetic Plus Racing Engine Oil SAE 20W-50 (12-Quarts)

Premium para-synthetic engine oil engineered for Harley-Davidson® V-Twin, racing, and high-performance applications.

High-performance and racing engines demand more than conventional oils can deliver. Schaeffer's 707 Extreme V-Twin Synthetic Plus Racing Engine Oil SAE 20W-50 is a sophisticated, high-zinc, multi-grade formulation built to withstand the extreme heat, stress, and mechanical demands of air-cooled and high-output powerplants.

Blended from the finest polyalphaolefin (PAO) synthetic base fluids and Group II+ base oils, this advanced 4-stroke engine oil incorporates two proven friction modifiers — Micron Moly®, a liquid-soluble molybdenum compound, and Penetro®, Schaeffer's own proprietary additive. Together, they plate rapidly to metal surfaces, dramatically reducing friction, lowering engine temperatures, and protecting critical components under the most demanding operating conditions.

Versatile enough for use in most 4-cycle air-cooled and water-cooled motorcycle and ATV engines — including those with a common sump for engine and transmission (non-metallic clutches only) — Schaeffer's 707 is equally at home on the track and the open road.

Meets and exceeds API Service Classification SM and Harley-Davidson® V-Twin specifications.

Key Performance Benefits

• Extreme Wear Protection — High-zinc formulation safeguards critical engine components under heavy load and high RPM
• Friction & Heat Reduction — Dual friction modifiers lower operating temperatures and reduce mechanical wear
• Thermal & Oxidative Stability — Resists breakdown under sustained high heat for consistent, reliable protection
• Strong Shear Stability — Maintains viscosity integrity under the mechanical stress of high-performance operation
• High Detergency — Keeps engines clean and free from deposits, varnish, and sludge
• Extended Drain Intervals — Premium formulation supports longer service intervals and reduced downtime
• Reduced Oil Consumption — Tight volatility control minimizes oil loss between service intervals
• Broad Compatibility — Suitable for most 4-cycle air-cooled and water-cooled motorcycle and ATV engines

Built for riders who refuse to compromise — and backed by the performance standards Schaeffer Oil has upheld for over 170 years.
