Always the optimum oil level

Groeneveld's unique Oilmaster oil management system ensures that the oil in the engine is always at the optimal level. Checking the oil level manually, is a thing of the past. This does not only save time but also ensures that there is never too little or too much oil in the engine, avoiding costly and time-consuming consequences.

Groeneveld's oil management system is applied in numerous sectors throughout the world. In public transport it is widely used by prominent bus manufacturers and operators. The solution is often used for earthmoving equipment, port and terminal equipment as well, in order to reduce daily maintenance and minimise the risk of unexpected downtime. The Oilmaster contributes significantly to higher efficiency, lower costs and a reduced environmental impact.

Always the correct level of oil

The Oilmaster ensures that there will always be the correct amount of oil in the engine. Not too little, but certainly not too much. The greatest benefit of this is the increased operational reliability by reducing the risk of engine damage. In addition, the system will prevent overfilling which could damage to the expensive exhaust gas after treatment system. And it makes time consuming manual oil gauging and filling redundant.

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. As a result, the Oilmaster will reduce the environmental impact of the engine.


The Oilmaster is suitable for many applications. A number of possible applications is 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.
