Common diesel oil-related concerns and how AMSOIL products may help
Diesel engines, particularly the OM642 BlueTEC series, face unique operational stresses. Proper lubrication is vital for emissions compliance and engine longevity.
| Concern | Why it matters | AMSOIL product from this lookup | How it may help | Important limitation |
|---|---|---|---|---|
| Emissions System Health | BlueTEC systems (SCR/DPF) are sensitive to oil additives. | EOTQT-EA | Designed for exceptional protection without harming emissions systems. | Requires proper monitoring of AdBlue/urea levels. |
| Turbocharger Wear | High heat and speed in the turbo require stable oil. | EOTQT-EA | Provides protection for the unique demands of diesel European vehicles. | Diagnosis required if turbo failure occurs. |
| Transmission Heat | Heavy towing or terrain can overheat ATF. | ATLPK-EA | Withstands the rigors of heavy towing and elevated temperatures. | Does not repair mechanical leaks. |
Diesel maintenance notes for this vehicle
- Engine Identification: Always verify your engine code is OM642 before purchasing parts to avoid confusion with the gasoline M276 variants.
- Emissions Monitoring: The BlueTEC system utilizes advanced NOx reduction technology. Owners should monitor exhaust fluid (AdBlue) levels and particulate filter health.
- Fuel System: This engine uses a high-pressure common rail injection system operating at approximately 1,600 bar.
Recall, TSB, and manufacturer communication notes
NHTSA recall research for the 2010 Mercedes Benz R350 identified one significant recall record:
- Campaign 16V081000 (Air Bags): Certain models may have a driver-side frontal air bag inflator module that could rupture upon deployment due to excessive internal pressure. This could result in metal fragments striking occupants.
Important: Always verify open recalls by using your specific Vehicle Identification Number (VIN) through the Mercedes-Benz website or NHTSA.
About this vehicle
The 2010 Mercedes-Benz R-Class is a luxury multi-purpose vehicle (MPV) that shares its underlying platform with the M-Class (W164) and GL-Class (X164). This specific diesel variant utilizes the OM642 engine family, a 3.0L V6 diesel engine characterized by its 72-degree V-angle and aluminum construction.
The OM642 is a significant engine in Mercedes-Benz history, designed to replace older straight-5 and straight-6 configurations. It features common rail direct injection and a variable nozzle turbocharger. A notable mechanical feature of this engine is the counter-rotating balance shaft located between the cylinder banks, which helps mitigate vibrations inherent to its V6 design.
As part of the Mercedes BlueTEC lineup, this vehicle employs advanced NOx reduction technology. Depending on the specific application, BlueTEC systems typically utilize Selective Catalytic Reduction (SCR) with Diesel Exhaust Fluid (AdBlue/urea injection) or NOx adsorber technology (DeNOx) combined with a diesel particulate filter (DPF). Owners should be aware that these emissions systems are complex and require specific monitoring of exhaust fluid levels and particulate filter health to ensure compliance and engine efficiency.
Note: While this model is identified as an R350 diesel, Mercedes-Benz also produced R350 models equipped with the M276 gasoline V6 engine. Maintenance requirements for these two engines are entirely different; always confirm your engine code before performing service.
