Yep. I had the same experience when I had a small oil leak (and I did test the level first, thus saving on underwear). Warning light Full on in level attitude = 1 quart low for me. Not an emergency - just time to add some oil.

Hi Bob;
I did the same thing and have had it come on a few times. I was
originally using the stock oil injection configuration from the engine sump,
but I also ran the oil sump vent to the air filter housing. The negative
pressure seemed to draw of a lot of oil mist (probably kept my turbo
compressor well lubricated) and this combined with the oil injection to have
high oil consumption. I did a few flights in excess of 4 hours and near the
end of these flights my low-oil LED would begin to flicker in some
attitudes. On one of the last of these extended flights the light was on
steady by the time I landed (by this time I'd realized that I had a
comfortable reserve... however it was still uncomfortable to have the light
on). IIRC, it was only 2 litres low when the light is on steady. When you do your next oil change, you should leave the power on to
power this warning, then have an assistant let you know when it comes on, as
you slowly drain the oil, then drain the remaining oil into a measuring
container.
