Keeping your 2008 Chrysler 300 running smoothly requires more than just filling the tank; it demands a complete understanding of the vehicle’s specific lubrication needs. The 3.5-liter V6 engine, a hallmark of Chrysler’s performance sedans from that era, relies on precise fluid specifications to maintain its durability and power output. Whether you are navigating daily commutes or engaging in spirited driving, using the correct viscosity and formulations is critical for minimizing wear, controlling operating temperatures, and extending the lifespan of internal components.

The 2008 Chrysler 300 with the 3.5L V6 engine (Engine Code G) is built on a platform that emphasizes a balance of luxury and performance. Proper lubrication is the foundation of this vehicle’s reliability. The engine requires 6.0 quarts of oil when performing a standard change with a filter replacement. For the cooling system, the reservoir holds a substantial 11.1 quarts, ensuring ample circulation to manage the heat generated by the powerful V6 engine. Understanding these specific capacities and fluid types is the first step toward optimal maintenance. Without the right fluids, the vehicle’s ability to handle extreme temperatures, long highway drives, or stop-and-go city traffic can be compromised, leading to premature wear on critical components.
Complete Fluid System Maintenance
Beyond the engine, the transmission and differential systems require specialized attention to ensure longevity. The 2008 300 may be equipped with different transmission configurations, such as the 5-speed NAG1 or the 4-speed 42RLE. For the NAG1, a total fill capacity of 8.1 quarts is required, while the 42RLE requires 8.8 quarts for a complete replacement. Using a high-performance synthetic fluid like AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid ensures that the transmission shifts smoothly and resists the sludge buildup common in high-mileage vehicles. The differential systems also vary by axle type, ranging from 1.3 pints for a 175mm front unit to up to 3.4 pints for larger rear differentials. AMSOIL’s SEVERE GEAR 75W-90 100% Synthetic Gear Lube provides the necessary extreme pressure protection for these gears, particularly for those with limited-slip differentials.
For vehicle owners who prioritize performance and longevity, the AMSOIL P.i. Performance Improver Gasoline Additive is a valuable addition. It helps restore lost horsepower and flow rates in fuel injectors, which is particularly beneficial for keeping the direct injection systems of the 300 running efficiently. Additionally, for those who store their vehicles seasonally, AMSOIL Gasoline Stabilizer and Engine Fogging Oil can protect internal components and fuel systems from rust during periods of inactivity. These additive products, combined with the core lubricants, create a comprehensive maintenance regimen that addresses all aspects of the vehicle’s mechanical health.
