AMSOIL 10W-40 | 3.78L (1 Gallon) 100% Synthetic Heavy-Duty Motor Oil

Engineered for high-stress engines, high-mileage vehicles, and heavy-duty applications requiring robust protection against extreme heat and heavy loads, this premium-imported 3.78-liter pack of AMSOIL 10W-40 is precision-formulated with advanced synthetic technology. It exceeds rigorous industry standards to deliver ultimate defense under harsh driving conditions like towing, off-roading, and high-temperature operation. With its superior film strength, it resists thermal breakdown, maintains stable viscosity, and provides exceptional defense for hardworking engines.

Key Benefits

• Robust High-Viscosity Protection: Forms an extra-strong fluid film designed to handle high-stress components, heavy hauling, and high-temperature operations without losing shear strength.

• Superior Wear Defense: Packed with heavy anti-wear additives to protect critical high-pressure areas such as bearings, cam lobes, and gears from metal-to-metal contact.

• Resists Thermal Breakdown: Overcomes the limitations of conventional oils by heavily reducing high-heat deposit formation, oil burn-off (volatilization), and oxidation.

• Optimized for Tough Conditions: Ideal for older vehicles, motor homes, high-mileage cars, and equipment subjected to heavy trailer pulling or stop-and-go abuse.

• Controls Oil Consumption: Helps reduce excessive oil consumption and thickening in engines that experience higher-than-normal usage rates.

• Extended Service Confidence: Formulated to neutralize acids and keep internal components cleaner for longer service intervals compared to standard conventional oils.

• Genuine Global Quality: As an authentic imported formula (3.78L), it delivers uncompromising international quality and heavy-duty reliability straight to your engine bay.
