I keep saving my panel as START738 and keep it as my default panel on startup. This seems to keep the clock running on my Maintenance Failures regardless of the livery I am flying. That fact is puzzling because all of the options selections remain specific to the particular aircraft. Anyway, gradually my oil levels decreased to where left was 10 and right was down to 9 (quarts).

 

When I started a flight the next day, the oil levels were back up to 20-20. Have any of you noticed this? I was thinking that I would have to perform a maintenance because I can find no specific procedure to top-off oil levels. Is this a built-in solution or could I just have inadvertently caused it by some action I completed? I am unaware of any adjustments or changes to anything that I made during that interim and BTW, the maintenance count-down clock still correctly reflects the total time remaining on each livery.

 

Is this an invisible ground maintenance employee that sees to this when it gets too low? Ah, a mystery!

I think that certain items are run by aircraft model (736, 73G, 738, 739), not by tail number. I could be very wrong. I keep using the default panel states, however, so I don't see any changes. I guess I should get on that. If anyone has better info, feel free to educate me.

Usually the aircraft will resume the state you last left it in, i only get the full oil and hyd quantity when i load a livery for the first time, just go into the FMC and reload the one called previous panel state or something like that, your fluid quantities will be back to where you left them

That is the strangeness of it all. I do keep a running panel setup. By that I mean I save each flight as "738START" and I have both 738-739 variants set to load that file on initial startup. Regardless of livery, my oil levels continuously drop with each flight. When I was down to 10 and 9 quarts I expected to see the yellow warning. Instead when I started the next flight all fluid levels were topped off (regardless of livery). A mystery for sure!
