Your very own little 737 services get costly. It’s stunning the amount it costs once in a while, genuinely crazy I let you know. I mean all costs so much, genuinely, it’s simply not reasonable. Yet, perhaps there are things you can do yourself – like replacing your own oil.

Changing the oil in your small aircraft is not as difficult as you might think, and you can save a lot of money by doing it yourself. While you are changing the oil it gives you a chance to look over the motor, and look for oil leaks, and other future potential problems. Below is how to change the oil in your personal aircraft yourself.


When you change the oil you should probably also change the air cleaners. Make sure you buy genuine parts from the 787 FMS manufacturer, or from a certified FAA repair station, and make sure the parts match up. Check your owner’s manual to make sure that you are buying the right grade of oil for the climate in which your aircraft generally operates.

 Now then, the first thing you must do after you have the proper parts; oil filter(s), air cleaner(s) – is to make sure you also have an oil pan. Whether you own a single-engine or twin-engine aircraft you will follow the same procedure.

 Run your aircraft for 10 to 15 minutes at the least to warm it up. Remove any part of that cowling as needed to get to the oil filter, air cleaner, and oil drain plug.

 Remove the drain plug, after placing the oil pan below it.

 Next remove the oil filter.

 After all the oil is drained out into the pan, put the plug back in, and put on the new oil filter.

 Then fill the fleet engineers with the designated amount of oil, but stop one-half of a quart less than what’s recommended.

 Next do the second engine, using the same steps, that is if you have a multiengine aircraft.

 Start both engines or the engine and run them for 2 to 3 minutes, make sure you put that cowling out of the way, as it will blow over and get damaged or hurt something.

 Turn off the engine(s) and use the dip stick to check the oil level(s). Add more oil only if appropriate. Next, take out the air cleaner and check to see if it needs to be changed. If it does, then do so as per the operations manual.

 Replace that cowling, and make sure all the fasteners are secure. Push on it and jiggle the cowling to make sure that it is on sturdy. Double-check your work to make sure that all the Zeus fasteners are fastened.

I hope this helps you save a little money!
