MOTUL 8100 POWER 5W-40

High-Performance Petrol & Diesel Engine Oil | 100% Synthetic – Ester

Type of use

MOTUL 8100 POWER 5W-40 is a fully synthetic, ester-based engine oil inspired by competition use. It is designed for high-performance petrol and diesel engines, whether naturally aspirated or turbocharged, with direct or indirect injection. It is intended for demanding driving conditions across a wide range of engine speeds and temperatures, including road and racing use.

It is suitable for petrol and diesel engines requiring an SAE 5W-40 oil meeting API SP. The formulation is compatible with biofuels, including E85, and exhaust after-treatment systems such as catalytic converters. It also helps protect downsized petrol engines against low-speed pre-ignition (LSPI).

The product is suitable for engines running on leaded or unleaded petrol, ethanol, LPG, diesel and biofuels, subject to the vehicle manufacturer’s requirements. This type of oil may be unsuitable for some engines, so check the owner’s manual before use.

Performance and benefits

  • Ester technology: The 100% synthetic formulation creates a resistant oil film at very high temperatures, helping protect against wear while supporting engine power and torque.
  • Stable oil pressure: Designed to maintain oil pressure during demanding road or racing use.
  • API SP performance: Provides oxidation resistance, deposit control, engine cleanliness and anti-wear protection. API SP also adds protection against LSPI in downsized, turbocharged, direct-injection petrol engines.
  • High-temperature protection: Helps control oil consumption and protect engine components when operating temperatures rise.
  • Start-up performance: The SAE 5W-40 viscosity supports faster oil flow and oil-pressure build-up at start-up.
  • Fuel compatibility: Suitable for applications using petrol, diesel, LPG, CNG and biofuels, including ethanol blends up to E85, where approved by the vehicle manufacturer.

LSPI is an abnormal combustion event that can occur in some downsized, turbocharged, direct-injection petrol engines. It can create very high pressure in the combustion chamber and potentially damage pistons. MOTUL 8100 POWER 5W-40 meets the API SP requirements developed to address this risk.

Standards and recommendations

Standard: API SP

Follow the vehicle manufacturer’s recommended oil change interval and adjust it according to how the vehicle is used. MOTUL 8100 POWER 5W-40 can be mixed with synthetic or mineral engine oils. Always consult the vehicle owner’s manual before use.
