Oilmaster HD

Always the optimum oil level

For many years, Groeneveld supplies the standard Oilmaster for combustion engines in buses, trucks, generator sets, earthmoving and construction equipment and many other applications. Specifically for demanding applications and for larger engines, Groeneveld developed the Heavy Duty Oilmaster, with a sturdy 15 litre aluminum tank.
In this way, the Oilmaster HD offers an excellent oil management solution for heavy dump trucks and other large earthmoving machines, port equipment, ships and many other demanding applications.

Always sufficient oil in the engine

The Oilmaster ensures that there will always be sufficient oil in the engine. The greatest benefit of this is the increased operational reliability by reducing the risk of engine damage caused by a too low or too high oil level. In addition, the system prevents overfilling, which could damage the expensive exhaust gas after treatment system.

Reduced environmental impact

The Oilmaster prevents increased fuel and oil consumption as a result of overfilling. This will also prevent an increased emission of harmful substances. Hereby, the Oilmaster will reduce the environmental impact of the equipment.


The Oilmaster HD is suitable for many applications. A number of possible applications are shown below. You are welcome to contact Groeneveld for tailored advice.

Reliable operation

The oil level in the engine is measured via a sensor. If the oil level drops below a set value, the Oilmaster will automatically fill half a litre of oil, fully independent of temperature and viscosity. Information about the amount of oil added is stored in the internal memory and can be used to perform preventive maintenance.
