Oil tank volume?

Anyone know what the entire oil tank volume is Including airspace for degassing the oil ? Actual amount of oil cold at mid or bottom sight glass ?

Thanks,
Will

Oil ta k volume is 2.7 litres....don't ask how I know this.

Ok the good book says 3 litres after oil change so 2.7 sounds right for operating volume.
Guessing around 3 1/4 to 3 1/2 litres total interior tank volume...
