The 2008 Kia Sorento with the 3.8L engine requires a specific amount of lubricant to ensure optimal function. When performing a routine oil change, the capacity for this engine is 6.0 quarts when including the AMSOIL Oil Filter. It is critical to refill the engine to the correct level and check the oil level after the refill. The drain plug torque specification for this vehicle is between 25 and 33 foot-pounds. Using the correct viscosity, such as 5W-20 or 5W-30, is vital for protecting the engine across all temperature ranges.
Proper fluid selection goes beyond just the engine oil. The cooling system for the Sorento has a capacity of 9.5 quarts. Maintaining the integrity of the cooling system is crucial to prevent overheating, especially during summer months or when the vehicle is under load. AMSOIL offers both Ethylene Glycol and Propylene Glycol Antifreeze and Engine Coolant. The Propylene Glycol formula is a concentrated coolant that requires mixing with distilled water and offers exceptional protection against corrosion and erosion for up to 150,000 miles or five years.
Transmission health is another critical area for this vehicle. The Sorento utilizes a hydraulic system for brake fluid, which requires DOT 3 specification. AMSOIL’s 100% Synthetic DOT 3 and DOT 4 100% Synthetic Brake Fluid meets both DOT 3 and DOT 4 standards, providing excellent responsiveness and a stable viscosity over a wide temperature range. This ensures that the braking system performs reliably in both freezing winter conditions and hot summer driving.
For the transfer case, the capacity is listed as unknown (U/K), but standard maintenance procedures apply for similar vehicles in this class. The front and rear differentials have specific capacities and requirements. The front standard differential requires 2.7 pints, while the rear standard differential requires 3.4 pints. If the vehicle is equipped with a limited-slip differential in the rear, a specific GL-5 lubricant with friction modifiers is required. The AMSOIL SEVERE GEAR® 80W-90 line is designed specifically for these applications, offering advanced protection against wear, rust, and corrosion while helping to control operating temperatures. For other conditions, the SEVERE GEAR® 75W-90 and SEVERE GEAR® 75W-110 also provide robust gear lube solutions.
Additionally, the power steering system benefits from a high-quality synthetic fluid. The AMSOIL 100% Synthetic Multi-Vehicle 100% Synthetic Multi-Vehicle Power Steering Fluid is formulated to reduce friction, resist heat for long fluid life, and provide strong anti-wear protection. This helps ensure that the power steering operates quietly and effectively, extending the life of the steering components. Regularly checking and replacing these fluids according to the maintenance schedule helps preserve the resale value and reliability of the vehicle.
About the Vehicle
The 2008 Kia Sorento represents a significant step forward for the Korean automaker in the mid-size SUV segment. During this model year, the Sorento was well-regarded for its blend of utility, family-friendly space, and driving dynamics that set it apart from many competitors in the market.

As a sport utility vehicle, the Sorento offered a spacious interior with versatile seating configurations, making it a popular choice for families who needed more cargo room than a sedan could provide but did not require the full size of a traditional body-on-frame truck. The 2008 model year, in particular, benefited from refined engineering that emphasized reliability and comfort. Owners often appreciated the smooth ride quality and the responsive handling characteristics that made it feel more like a car than a typical SUV. The platform utilized by this generation of Sorento contributed to its reputation as a practical, value-oriented crossover that could competently handle both on-road comfort and light off-road excursions.
Owners of the 2008 Sorento typically find it to be a durable vehicle when maintained properly. The V6 engine, known for its smooth power delivery, pairs well with the automatic transmission to provide confident acceleration. While the vehicle offers a range of features depending on the trim level, its core appeal lies in its ability to serve as a reliable daily driver that can also accommodate larger loads or passengers. With proper attention to its lubrication needs, this SUV continues to be a solid option for those seeking a capable and comfortable vehicle.
