AMSOIL 5W-40 MS 100% Synthetic European Motor Oil delivers the precise combination of protection, cleanliness, and emissions system compatibility that modern European gasoline and diesel engines demand. Built around advanced synthetic base oils and a carefully balanced additive package, it covers a wide range of OEM specifications from BMW, Mercedes-Benz, Porsche, Volkswagen, and more.
European engines operate under conditions that push motor oil harder than most drivers realize. Tighter tolerances, turbocharging, direct injection, and extended OEM drain intervals all place enormous stress on the oil film. Add modern exhaust aftertreatment devices like diesel particulate filters and catalytic converters, and you need an oil that protects the engine without poisoning the emissions hardware. A generic 5W-40 synthetic simply is not formulated with those constraints in mind.
MEETS STRICT EUROPEAN OEM SPECIFICATIONS
This 5W-40 carries ACEA C3 approval along with a long list of manufacturer-specific credentials: Mercedes-Benz 229.51, BMW Longlife-04, Porsche A40, VW 502.00 and 505.01, GM dexos 2, Chrysler MS-10850, Ford WSS-M2C917-A, and Renault 0700/0710. It also meets API SN, SM, and CF. If your BMW X3, Mercedes C-Class diesel, VW Golf TDI, or Porsche Macan calls for any of these specs, this oil covers it. That breadth of coverage makes it a practical choice for shops and owners managing multiple European vehicles.
PROTECTS EMISSIONS SYSTEMS WITH OPTIMIZED SAPS CHEMISTRY
Diesel particulate filters and gasoline particulate filters are sensitive to sulfated ash, phosphorus, and sulfur content in motor oil. Too much of any one element accelerates filter clogging and shortens the life of catalytic converters. AMSOIL formulates this 5W-40 with a precisely controlled SAPS balance that meets ACEA C3 low-SAPS requirements while maintaining a Total Base Number of 8.0, enough alkalinity reserve to neutralize combustion acids over extended service intervals.
THERMALLY STABLE FOR TURBOCHARGED ENGINES
Turbochargers in vehicles like the BMW 335i, Mercedes-AMG C43, and VW 2.0L TSI push exhaust-side temperatures well above 1,000°F, and oil flowing through the turbo bearing housing absorbs a significant share of that heat. This formulation resists thermal breakdown and deposit formation in high-heat zones. Its Noack volatility of just 7.2% weight loss (ASTM D5800) means less oil is lost to evaporation at elevated temperatures compared to oils that barely meet the ACEA C3 limit of 13%. A flash point of 226°C (438.8°F) further reflects the thermal resilience of the synthetic base stock.
COLD-WEATHER PERFORMANCE FOR YEAR-ROUND USE
Cold starts are where most engine wear occurs, and turbocharged engines are especially vulnerable to oil starvation in the turbo bearing before full oil pressure builds. This 5W-40 posts a pour point of -39°C (-38.2°F) and a cold-crank simulator viscosity of 5,628 cP at -30°C. It flows quickly at startup in cold climates, reaching critical lubrication points in the valvetrain and turbo cartridge faster than oils that thicken excessively in subzero conditions.
SHEAR-STABLE PROTECTION ACROSS LONG DRAIN INTERVALS
European automakers commonly specify drain intervals of 10,000 to 15,000 miles or more. Oil that shears down and loses viscosity before the next service leaves bearings, cam lobes, and piston rings with less protection than they need. AMSOIL uses shear-stable synthetic base oils that maintain their viscosity grade throughout the OEM-recommended drain interval. The high-temperature/high-shear viscosity of 4.1 cP (ASTM D5481) confirms a strong, durable oil film under the most demanding operating conditions, well above the 3.5 cP minimum required by ACEA C3.
SPECIFICATIONS AND COMPATIBILITY
AMSOIL 5W-40 MS 100% Synthetic European Motor Oil (AFL) meets or exceeds: API SN, SM, CF; ACEA C3; Mercedes-Benz 229.51; BMW Longlife-04; Porsche A40; VW 502.00, 505.01; GM dexos 2; Chrysler MS-10850; Ford WSS-M2C917-A; Renault 0700, 0710.
Compatible with other synthetic and conventional motor oils. Mixing oils will reduce performance benefits and drain interval capability. AMSOIL does not support extended drain intervals where oils have been mixed. Aftermarket oil additives are not recommended.
SERVICE LIFE
Recommended for the extended drain intervals established by the vehicle manufacturer. Change the oil filter at the time of each oil change.
