The 2007 Mercedes-Benz S600, powered by its massive 5.5-liter 12-cylinder twin-turbo engine, is a masterpiece of German engineering. This vehicle represents the pinnacle of luxury and performance, featuring a robust V12 powertrain that delivers smooth, effortless acceleration. However, this sophisticated engine and its associated systems place unique demands on lubrication. Unlike standard passenger cars, the S600 requires fluids specifically formulated to handle high thermal loads, turbocharger stress, and the strict tolerances of European components. Using the wrong oil or fluid can lead to premature wear, sludge buildup, and expensive repairs. Proper lubrication ensures that the high-performance engine runs smoothly, maintains optimal fuel efficiency, and delivers the reliability owners expect from a flagship sedan.

The heart of the 2007 S600 is the M275 engine, a 5.5-liter V12 with twin intercoolers and direct fuel injection. This powerplant generates significant horsepower and torque, but the internal stresses are immense. High temperatures are a constant byproduct of this performance, making the choice of engine oil critical. AMSOIL European Motor Oils are designed to address the specific requirements of these engines, providing a robust barrier against wear while maintaining fluidity in extreme cold. The capacity for this engine is 9.5 quarts with a filter change, though models equipped with an external oil cooler may require additional fluid. Regular oil changes are vital, as the synthetic formulation resists breakdown and deposit formation, keeping the engine clean and the timing chain tensioners functioning correctly.
Complete Fluid Care for the S600
While the engine is the most critical component, the other systems in the S600 also require specialized attention. The transmission, a 5-speed automatic with a torque converter, demands a fluid that can handle the weight of the sedan and the sudden bursts of power. Using a high-quality synthetic transmission fluid helps prevent the wear and temperature spikes that can lead to shifting issues. The cooling system, which holds 9.3 quarts of fluid, must be capable of managing the heat generated by the V12. AMSOIL antifreeze and coolant options provide excellent corrosion protection, which is essential for the diverse metals found in the cooling passages and radiator.
Safety and control are paramount in a vehicle of this caliber, and the braking system relies on fluid that will not compress or boil under heavy use. AMSOIL DOT 3 and DOT 4 Synthetic Brake Fluid exceeds the specifications required by Mercedes-Benz, ensuring consistent pedal feel and rapid response. Similarly, the power steering system benefits from a fluid that prevents seal hardening, a common issue in older luxury vehicles. The recommended fluid reduces friction and protects against leaks, maintaining the precise steering response the S600 is known for.
Additional Maintenance and Protection
For owners who store their S600 during the off-season or drive it under severe conditions, additional protection is available. AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, preventing the varnish and gum buildup that can plague direct injection systems. Engine Fogging Oil provides a protective barrier during long periods of storage, preventing rust on internal components. For those who want to maximize performance, AMSOIL P.i. Performance Improver is a powerful gasoline additive that can restore lost horsepower and clean fuel injectors, ensuring the engine operates at peak efficiency.
Keeping the vehicle looking as pristine as it drives is also part of ownership. A comprehensive range of detailing products is available, from silicone sprays that protect rubber and plastic to heavy-duty degreasers that clean the engine bay. These tools help maintain the condition of the S600, protecting the finish from UV rays and road grime. By utilizing the full range of AMSOIL products, owners can ensure their vehicle receives the highest level of care, from the crankcase to the wheel wells.
Vehicle Background and Performance Heritage
The 2007 Mercedes-Benz S600 is more than just a luxury sedan; it is a rolling monument to automotive engineering excellence. Part of the W220 generation (produced from 1998 to 2005, with the facelifted W220 continuing into 2006/2007), the S600 represents the V12 badge of the S-Class lineup. This model was designed to compete with the most exclusive sedans on the market, offering a level of opulence and performance that few vehicles can match. The interior is a sanctuary of comfort, featuring Nappa leather, wood trim, and advanced technology for its time, including the COMAND infotainment system and sophisticated driver aids.
The 5.5-liter 12-cylinder engine is the star of the show. With twin turbochargers and a sophisticated variable valve timing system, it delivers power smoothly and effortlessly. This is not a vehicle that screams for attention with rough horsepower; instead, it provides a profound sense of thrust and refinement. The chassis is tuned for a balance between a smooth, floating ride and sharp handling, allowing the S600 to navigate curves with surprising agility while absorbing road imperfections. It is a car that feels substantial and planted, inspiring confidence in any driving condition.
Despite its robust build, the S600 does face specific challenges as it ages. One of the most common issues involves the oil consumption and sludge buildup within the engine, particularly in the oil gallery areas that feed the cylinder heads. Using a high-quality synthetic oil with strong detergent packages helps prevent this sludge, keeping the hydraulic lifter and timing chain tensioners functioning correctly. Another prevalent problem is the failure of the air conditioning compressor and associated seals, often exacerbated by aging rubber components. High-quality synthetic fluids and conditioners can help keep these seals soft and pliable, reducing the risk of leaks and maintaining cooling efficiency. Additionally, the electronic components, such as the EGR valve and various sensors, can become coated in carbon deposits over time. Using fuel additives like AMSOIL P.i. can help clean these injectors and valves, restoring performance and preventing stalling issues. Finally, the air suspension system, if equipped, relies on air struts and seals that can develop leaks; while not fluid-dependent, maintaining a clean, dry undercarriage with protective sprays can help reduce corrosion on the suspension components, extending their life.
Owners of the S600 who adhere to a strict maintenance schedule using premium synthetic lubricants often find that these vehicles continue to perform flawlessly for hundreds of thousands of miles. The investment in the correct fluids is an investment in the longevity of the machine, ensuring that this grand touring sedan remains a joy to drive for years to come.
