Diesel maintenance notes for this vehicle
Maintaining a BlueTEC diesel engine requires specialized attention to emissions components. Because this vehicle utilizes advanced NOx reduction technology, owners must monitor Diesel Exhaust Fluid (DEF/AdBlue) levels and the condition of the particulate filter to prevent reduced performance or “limp mode.” Additionally, maintaining high fuel quality is vital for protecting the common rail direct injection system and turbocharger.
Common diesel oil-related concerns and how AMSOIL products may help
| Concern | Why it matters | AMSOIL Product | How it may help | Limitation |
|---|---|---|---|---|
| Emissions System Health | Diesel engines use complex SCR/DPF systems. | EOTQT-EA | Designed for exceptional protection without harming emissions systems. | Does not repair existing damage. |
| Turbocharger Wear | High heat and speed in turbochargers require stable oil. | EOTQT-EA | Provides precise blend of synthetic base oils for protection. | Requires regular oil change intervals. |
| Transmission Heat | Heavy towing or terrain increases ATF temperature. | ATLPK-EA | Withstands rigors of heavy towing and elevated temperatures. | Diagnosis required for mechanical failure. |
Common maintenance concerns for this vehicle
Based on technical research, owners should consider the following:
- Emissions Aftertreatment: Regular monitoring of DEF levels and particulate filter health is essential for BlueTEC systems.
- Fuel System Integrity: The high-pressure common rail system requires clean fuel to prevent injector issues.
- Active Curve System (ACS): Note that some Mercedes models have had recalls regarding ACS reservoir oil foaming; ensure your system is functioning correctly.
Recall, TSB, and manufacturer communication notes
NHTSA research indicates the following recall information for the 2016 Mercedes Benz GL350:
- Communication Software: A recall (Campaign 19V787000) was issued regarding a software fault in the emergency call system (eCall) that could cause inaccurate vehicle location data.
- Suspension/ACS: A recall (Campaign 18V272000) addressed concerns where oil in the Active Curve System (ACS) reservoir might foam and leak if levels are below minimum, potentially increasing fire risk.
- Air Bags: A recall (Campaign 16V903000) was noted regarding occupant classification sensors.
Note: Always verify open recalls by checking your specific VIN through the Mercedes-Benz website or NHTSA.
About this vehicle
The 2016 Mercedes-Benz GL350 is part of the X166 generation of the GL-Class, a full-size luxury crossover SUV. This model is powered by the OM642 engine, a 3.0L V6 diesel powerplant characterized by its 72-degree V configuration and aluminum construction.
As a BlueTEC model, this vehicle utilizes Mercedes-Benz’s advanced NOx reduction technology to meet emissions standards. This typically involves Selective Catalytic Reduction (SCR) using Diesel Exhaust Fluid (AdBlue), or NOx storage catalysts combined with a diesel particulate filter (DPF). The OM642 engine family is widely recognized for its common rail direct injection and variable nozzle turbocharger technology. It was designed to replace older straight-5 and straight-6 diesel configurations, utilizing a counter-rotating balance shaft to mitigate the inherent vibrations of the V6 design.
Owners often research the health of the diesel exhaust aftertreatment system, as BlueTEC technologies involve complex components like urea injection systems that require consistent monitoring. Maintaining strict oil change intervals and high fuel quality is vital for protecting the high-pressure common rail components and the turbocharger.
