Diesel maintenance notes for this vehicle
Maintaining the OM642 diesel engine requires attention to several critical systems. Because this vehicle utilizes BlueTEC technology, monitoring emissions components like the Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) is essential. Precision in fuel filtration and high-quality oil are paramount due to the high pressures of the common rail system.
Coolant Specifications
The cooling system capacity is 10 quarts. AMSOIL offers both a 50/50 pre-mix (ANTPC1G-EA) and a concentrated version (ANT1G-EA) that requires mixing with distilled or high-quality water.
Common diesel oil-related concerns and how AMSOIL products may help
Diesel engines face unique stresses such as soot loading and turbocharger heat. Proper lubrication can mitigate these issues.
| Concern | Why it matters | AMSOIL Product | How it may help | Limitation |
|---|---|---|---|---|
| Emissions System Health | BlueTEC systems are sensitive to oil additives. | EOTQT-EA | Designed for exceptional protection without harming emissions systems. | Requires proper maintenance of DPF/SCR. |
| Heavy Towing/Heat | High temperatures can degrade standard oils. | ATLPK-EA | Withstands rigors of heavy towing and elevated temperatures. | Diagnosis required for mechanical failure. |
| Cold Weather Starts | Thick oil can hinder startup in winter. | EOTQT-EA | 0W viscosity provides flow in low temperatures. | N/A |
Common maintenance concerns for this vehicle
Owners of the 2007 ML320 should focus on several key areas to ensure longevity:
- Emissions Management: Monitoring BlueTEC components, including Diesel Exhaust Fluid (AdBlue) levels and particulate filter clarity.
- Turbocharger Health: Ensuring oil quality is high to protect the variable nozzle turbocharger.
- Fuel System Integrity: Maintaining clean fuel through precise filtration to protect the common rail direct injection system.
Recall, TSB, and manufacturer communication notes
NHTSA research indicates two significant recalls for this vehicle family regarding the braking system:
- Campaign 22V315000: Moisture may accumulate in the brake booster housing, potentially causing reduced performance or failure.

Important: Owners are advised to verify open recalls by VIN through an authorized Mercedes-Benz dealer or the NHTSA website.
About this vehicle
The 2007 Mercedes-Benz ML320 is a mid-size luxury SUV part of the M-Class nomenclature. It is powered by the OM642 engine, a 3.0L V6 diesel characterized by its 72-degree V configuration and aluminum construction. This engine was designed to replace previous straight-5 and straight-6 diesel engines, utilizing common rail direct injection and a variable nozzle turbocharger for optimized performance and efficiency.
A significant engineering feature of the OM642 is the counter-rotating balance shaft, which helps mitigate the vibrations inherent in its V6 design. The engine maintains a high compression ratio of 18.0:1. This model is closely associated with BlueTEC technology, a suite used by Mercedes-Benz to manage NOx emissions through advanced systems like selective catalytic reduction (SCR). Because of this complexity, owners often research the management of diesel exhaust fluid and particulate filter maintenance to ensure the vehicle meets emissions standards effectively.
