Perhaps the most common and critical maintenance procedures on any marine engine are the procedures related to filter and oil changes. Oil breaks down under use and heat, and changing the oil according to the specifications in the manual is important in adhering to the conditions of your warranty. The standard oil change interval for our VGT Series is 100 hours.
However, we are occasionally asked by customers if this interval can be extended. The answer is, “Yes”, under certain conditions described below. The interval need to change oil is primarily determined by both engine load and environment.
MarineDiesel’s VGT series marine engines have a standard oil change interval of 100hrs, however this has been selected due to variables in regional use such as load cycles, quality of fuel and lubrication oil etc. It is allowed to extend the oil change intervals under certain conditions; these must be closely monitored and given written approval by an authorized Marinediesel distributor.
The extended oil change intervals are only allowed on applications that have a predictable usage cycle, for example you are not allowed to perform below tests on a 200hr cycle where the engine is used at idle to then drastically alter the usage after extension approval.
Follow the recommendations below:
At 100 hrs: Take an oil sample and send to get it analysed. If the oil comes back as good to use then continue operations for another 50hrs. Top up engine oil if needed
At 150 hrs: Take an oil sample and send to get it analysed. If the oil comes back as good to use then continue operations for another 50hrs. Top off engine oil is needed.
Next 50hr check: Same as above
The maximum allowed oil change interval is set to 250hrs but this is not possible for all applications as oil tests may show.
Use oil and filter as specified in the engine technical manual.
