Features

• 100% Synthetic ESTER-based formula derived from competition - leverages the same foundational technology as Motul's motorsport-grade lubricants for maximum oil film resistance at extreme temperatures
• Exceptionally high HTHS viscosity of 4.3 mPa.s at 150°C maintains a robust, stable oil film under the severe shear forces of high-performance and track driving
• High viscosity index of 187 ensures excellent viscosity stability across the full temperature range, from cold starts to sustained high-RPM operation
• Optimized SAE 5W-50 grade delivers maximum engine reliability and outstanding protection against fuel dilution - critical for flex-fuel, forced-induction, and high-load applications
• LSPI (Low Speed Pre-Ignition) protection guards downsized, turbocharged direct-injection engines against destructive abnormal combustion events and piston damage
• Outstanding oxidation and thermal resistance prevents black sludge, deposit formation, and viscosity increase from combustion residues throughout the drain interval
• Very low pour point of -45°C / -49°F enables excellent cold-start oil flow and fast pressure build-up even in cold climates
• High flash point of 238°C / 460°F demonstrates superior thermal stability and resistance to volatility and oil burn-off at sustained operating temperatures
• Very good compatibility with catalytic converters and exhaust aftertreatment systems
• Full biofuel compatibility including Ethanol E85, LPG, CNG, and biodiesel blends up to available station ratios

Product Description

Motul 8100 Power 5W-50 (P/N 111812) is the 5-liter format of Motul's competition-derived, 100% synthetic ESTER engine oil engineered for demanding high-performance and motorsport applications. Succeeding the discontinued Motul Sport 5W-50 line, the 8100 Power formula draws on ester base stocks - the same core technology found in Motul's 300V race oils - to deliver unmatched oil film resistance under extreme heat and mechanical stress. With an HTHS viscosity of 4.3 mPa.s at 150°C and a viscosity index of 187, this oil sustains a thick, stable protective film even under the intense shear forces generated during sustained high-RPM driving, extended track sessions, and wide-open-throttle acceleration. The 5-liter bottle is ideal for full oil changes on engines with larger sumps and makes it the practical choice for performance shops, fleet maintenance, and enthusiasts running regular track days.

The 8100 Power 5W-50 meets both the API SP performance standard and the Ford WSS-M2C931-D/E1 OEM performance specification - the factory-required oil for a range of high-performance Ford gasoline engines, including the Focus RS 2.3 EcoBoost AWD, Ford GT (2016+), Mustang GT350 and GT350R (2018+), Mustang GT V8 5.0L, Boss 302 V8 5.0L, Mustang GT350 (2015+), Shelby GT500 (2006+), and the Ford GT V8 5.4L (2004-2006). Built-in LSPI (Low Speed Pre-Ignition) protection safeguards turbocharged direct-injection engines against the destructive pressure spikes associated with this pre-combustion phenomenon. The formula offers full biofuel compatibility including Ethanol E85, LPG, CNG, and biodiesel blends, making it well-suited for modified, flex-fuel, and forced-induction builds running alternative fuel mixes.

The optimized SAE 5W-50 viscosity grade provides maximum reliability and outstanding resistance to fuel dilution - a key concern in high-load, boosted, and performance-tuned applications. A low pour point of -45°C / -49°F ensures reliable cold-start flow and rapid oil pressure build-up in cold climates, while the high flash point of 238°C / 460°F confirms exceptional thermal stability and low volatility under sustained high operating temperatures. Drain interval should be set according to manufacturer recommendations and adjusted to match your specific usage conditions, including track frequency and driving intensity. Always consult your vehicle's owner's manual to confirm SAE 5W-50 is the specified or acceptable viscosity grade before use.
