Diesel maintenance notes for this vehicle
Maintaining a Mercedes BlueTEC diesel requires attention to the complex emissions systems and high-pressure injection components. Owners should focus on:
- Emissions Systems: Monitoring the health of the particulate filter and NOx storage catalysts is essential for long-term operation.
- Fuel Quality: Using high-quality diesel fuel is critical to protect common rail direct injection components operating at approximately 1,600 bar.
- Turbocharger Care: Ensuring consistent lubrication helps manage the variable nozzle turbocharger system.
Common diesel oil-related concerns and how AMSOIL products may help
Diesel engines face unique stresses such as soot loading and high operating temperatures. The following table outlines how specific AMSOIL products can support your maintenance needs.
| Concern | Why it matters | AMSOIL Product | How it may help | Limitation |
|---|---|---|---|---|
| Engine Wear | High-pressure diesel combustion increases friction. | EOTQT-EA | Provides exceptional engine protection. | Does not repair existing wear. |
| Emissions Damage | Incorrect oil can harm BlueTEC systems. | EOTQT-EA | Designed not to harm emissions systems. | Requires proper maintenance intervals. |
| Transmission Heat | Heavy towing can overheat ATF. | ATLPK-EA | Withstands rigors of heavy towing and high temps. | Diagnosis required for mechanical failure. |
Common maintenance concerns for this vehicle
Based on technical research, owners of the 2007 GL320 should be aware of several key areas:
- Turbocharger Longevity: The variable nozzle turbocharger is a critical component that relies on clean oil.
- Injection System Health: The high-pressure common rail system requires clean fuel and precise lubrication.
- Emissions Management: Monitoring diesel exhaust fluid (where applicable) and particulate filter status is vital for BlueTEC technology.
Recall, TSB, and manufacturer communication notes
NHTSA research indicates the following recall information for certain 2006-2012 Mercedes-Benz GL-Class vehicles:
- Brake Booster Corrosion: There are recall records (Campaign 22V315000 and 24V298000) regarding moisture accumulation in the brake booster housing unit. This can cause corrosion, potentially leading to reduced brake performance or failure.
Important: Owners are advised to verify if their specific vehicle is affected by these recalls by contacting a Mercedes-Benz dealer or checking their VIN on the official NHTSA website. Do not rely solely on this summary for safety decisions.
About this vehicle
The 2007 Mercedes-Benz GL320 is powered by the OM642 engine, a cornerstone of the Mercedes-Benz diesel lineup. This 3.0-liter V6 engine features an aluminum block and heads in a 72-degree V configuration. Designed to replace older straight-cylinder configurations, the OM642 utilizes common rail direct injection and a variable nozzle turbocharger to balance performance with efficiency.
Technically, the engine incorporates a counter-rotating balance shaft between the cylinder banks to mitigate the vibrations inherent in its design. The injection system operates at high pressures (approximately 1,600 bar) with a compression ratio of 18.0:1. As part of the Mercedes BlueTEC ecosystem, this vehicle utilizes advanced emissions technology, which may include particulate filters or NOx storage catalysts to manage environmental impact.
Owners often focus their maintenance efforts on the longevity of the turbocharger, the health of the common rail components, and the management of complex emissions sensors. Because these systems are highly sensitive to fluid quality, maintaining high standards for diesel fuel and engine oil is a primary concern for long-term reliability.
Common questions about this vehicle’s diesel oil and maintenance
How much oil does my 2007 GL320 take?
The engine requires 9 quarts of oil when performing a service that includes a filter change. Always check the level after refilling.
What is the correct torque for the oil drain plug?
The oil drain plug should be torqued to 22 ft/lbs.
Can I use any diesel oil in my Mercedes BlueTEC?
It is important to use oil designed for European diesel engines. The AMSOIL lookup lists EOTQT-EA, which is designed for the unique demands of European diesel vehicles and is formulated to protect emissions systems.
