Complete Coverage

AMSOI 5W-40 Synthetic European Car Formula meets and often exceeds strict European manufacturer specifications. Its shear-stable synthetic base oils and high-quality anti-wear additives provide outstanding protection in high-temperature conditions and deliver dependable performance throughout the long drain intervals recommended by European manufacturers.

Emissions System Protection

AMSOI 5W-40 Synthetic European Car Formula features precisely balanced formulations that consider the needs of modern exhaust treatment devices. Protecting sensitive emissions systems depends on using the optimal blend of SAPS (sulfated ash, phosphorus and sulfur) to keep these systems functioning properly.

Superior Engine Cleanliness

The excellent oxidation stability, heat resistance and detergency properties of AMSOI 5W-40 Synthetic European Car Formula help keep engines clean. It is specifically designed to prevent sludge and varnish deposits, reduce oil consumption, extend engine life and provide maximum performance.

Excellent For Turbochargers

AMSOI 5W-40 Synthetic European Car Formula has a robust composition that shields engines from the high temperatures produced by turbochargers. Its thermally stable oil formulation resists deposit formation and cools turbochargers. Its low pour point protects turbo-chargers against oil starvation in subzero temperatures and ensures a rapid return to appropriate oil pressure at startup.

Service Life

Recommended for the extended drain intervals established by the vehicle manufacturer. Change oil filter at time of oil change.


AMSOI 5W-40 Synthetic European Car Formula Synthetic Motor Oil is compatible with other synthetic and conventional motor oils. Mixing AMSOIL motor oil with other oils, however, will shorten the oil's life expectancy and reduce its performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL motor oils.
