5 Tips for Servicing Your Oil System

Feb. 7, 2017 | | 2 min read

To maintain a high level of engine performance, you need to monitor and service your oil system properly. Follow these 5 best practices to get a clear picture of your oil status and optimize your engine’s condition.

1. Respect min and max levels

Performing aircraft oil system servicing at a level below the minimum can result in an insufficient oil supply during operation. On the other hand, servicing the oil system at a level above the maximum may impede proper operation of the air/oil separator. This can lead to carbon seal distress and loss of oil through the engine breather tube. When your oil level is too high or too low, it could lead to pressure fluctuations, low-pressure indications and engine damage.

2. Monitor oil usage over at least 10 hours

To effectively perform aircraft oil servicing, be sure to continuously monitor your oil consumption. Careful monitoring will give you advance warning of abnormal oil consumption so that you can carry out pre-emptive troubleshooting. We recommend that you collect data and plot oil consumption trends over at least 10 hours of accumulated flight time. This will give you a more realistic portrait of your engine’s functioning to produce a more accurate reading.

3. Be consistent with timing when performing engine oil system servicing

Always service your engine oil system at the same time after engine shutdown. Whatever point in time you choose, stick to it. This is fundamental to obtaining reliable and accurate oil consumption trend data.

4. Use the same level every time

Likewise, you should always service your oil to the same level. If you fill the oil to the maximum one day and to the minimum the next, it could skew your data. No matter the oil level indicator configuration, we recommend always servicing your oil to a level somewhere between the minimum and maximum.

5. Use the right device

When topping up your oil, be sure to use an appropriate filling device such as a funnel or fluid servicing cart with the appropriate attachment. Using the wrong device could lead to spills and leakages, as well as an inaccurate oil usage recording.

While also following the standard procedures in your maintenance manual, put these critical tips into practice at all times during the engine oil system servicing to maintain a normal main oil pressure.
