Engine Oil and Maintenance Specs
Proper lubrication starts with selecting the correct viscosity grade for your climate and driving habits. The 2008 Mercedes-Benz E63 AMG specifies a viscosity of 0W-40 or 5W-40 for all temperatures. The engine oil capacity is 9.3 quarts when changing the Oil Filter. It is important to note that on models equipped with an oil cooler, additional oil may be required if the cooler is drained during the service. After refilling, allow the engine to sit for at least five minutes before checking the oil level to ensure an accurate reading. When tightening the oil drain plug, the torque specification is 22 ft/lbs.
AMSOIL 5W-40 FS and AMSOIL 0W-40 FS are both excellent choices for this vehicle. These oils are designed specifically for European vehicles that have unique demands on their lubricants. The European formula features a precise blend of synthetic base oils and premium additives that provide outstanding protection against sludge, varnish, and deposits. Using these full synthetic oils helps maintain engine cleanliness and extends the life of the 6.3L V8, allowing for extended drain intervals compared to conventional oils.
Transmission Fluid Requirements
The transmission in the E63 AMG requires careful attention, particularly regarding the specific fill requirements for the 7-speed automatic transmission (722.9). The total fill capacity is 9.3 quarts. There are two distinct variants of this transmission, and the fluid selection depends on the specific datacard code of the vehicle.
For models without code A89 (Reduced-Friction), the vehicle requires the standard transmission fluid specification. For models with the A89 code, which indicates a reduced-friction application, a different specification is required. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid and the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid are formulated to handle these precise requirements. These fluids remain fluid in sub-zero temperatures and provide reserve protection during heavy use and abuse, ensuring the transmission withstands the rigors of high-performance driving. Using the correct fluid prevents sludge, wear, and temperature-related problems that can lead to costly repairs.
Cooling System Fluids
The cooling system is vital for managing the heat generated by the E63 AMG engine. The system capacity is 12.5 quarts. Owners have the choice between a pre-mixed solution or a concentrated formula. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix that is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, making it safe for all cooling system metals. It offers protection for up to 150,000 miles or five years.
For those who prefer a concentrated AMSOIL Propylene Glycol Antifreeze and Engine Coolant, this option provides a robust alternative. This concentrated formula requires mixing with distilled or high-quality water but offers protection for up to 150,000 miles or 5 years in passenger cars. It greatly surpasses standards for metallic corrosion and erosion and is compatible with all other antifreeze colors, allowing for easy top-offs.
Brake and Power Steering Fluids
Safety is paramount for a vehicle of this caliber. The 2008 Mercedes-Benz E63 AMG recommends a DOT 4 fluid for the braking system, specifically approved under MB Sheet 331.0. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an excellent replacement that provides stable viscosity over a wide temperature range. This stability ensures excellent ABS and traction-control responsiveness, which is crucial for handling the high speeds and heavy weight of the E63 AMG.
For the steering system, the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid is recommended for the PS031 specification. This fluid reduces friction and helps seals remain soft, preventing leaks that are common in aging power steering systems. It resists heat for long fluid life and provides strong anti-wear protection, ensuring quiet operation and reliable steering feel.
Why Proper Lubrication Matters
The 6.3-liter V8 engine in the E63 AMG is a masterpiece of engineering, but it operates under extreme conditions. High RPMs, heavy loads, and rapid temperature changes place immense stress on engine components. Synthetic lubricants provide a stronger molecular bond than conventional oils, maintaining their viscosity and protective properties longer. This reduces friction, minimizes wear on pistons, bearings, and camshafts, and keeps the engine running smoother. By using AMSOIL synthetic fluids, owners ensure that their vehicle maintains its performance characteristics and reliability over the long haul.
