Marathon Endurance Synthetic Blend 10W40 Oil is a premium-quality passenger car motor oil (PCMO) designed to protect modern engines.

Engineered with an advanced additive package and refined base oils, this high-performing 10w40 oil offers enhanced durability, thermal stability, and performance.

Whether you drive a domestic or imported vehicle, this 10w40 oil provides the robust protection needed for today’s turbocharged gasoline direct-injection (TGDI) engines, as well as conventional gasoline-fueled and flex-fuel vehicles. It’s also ideal for light trucks, SUVs, and gasoline-electric hybrids that demand reliable performance in both stop-and-go traffic and highway driving.

Marathon Endurance Synthetic Blend 10W-40 exceeds current ILSAC GF-6 and API SP performance standards.

It offers superior pre-ignition control, helping reduce the risk of low-speed pre-ignition (LSPI), a common concern in TGDI engines. The formulation also combats timing wear, ensuring long-lasting performance and engine longevity.

This 10w40 engine oil is engineered to protect critical engine components like pistons, valve trains, and camshafts. Its excellent detergency resists sludge and varnish formation, keeping engines clean and responsive. The oil also protects emission system catalysts, promoting longer catalyst life and better environmental compliance.

Cold morning starts are no problem thanks to excellent low-temperature pumpability.

Even in winter, your engine receives the immediate lubrication it needs to avoid metal-on-metal wear. Additionally, this 10w40 oil provides oxidation stability and viscosity control at high temperatures. This makes it ideal for extended drain intervals and high-mileage engines.

If you’re looking for a 10w40 engine oil that balances performance, protection, and fuel efficiency, Marathon Endurance Synthetic Blend delivers on all fronts. It’s the trusted choice for motorists who demand more from their oil—mile after mile.
