You asked how much oil came out of the vent port.
The fuel tank is 360 cc the bottle is 500 cc.
The engine is 300 rpm fat at WOT, the LSN is set as lean as possible to have good quick transition to WOT.
50% of the tank was run at WOT the rest was run at mid throttle and maybe three minutes at idle.
I would guess a little less than 1 oz is in the bottle (29 cc).

[edit here]
The fuel, is a mix of 1 gal Cool Power, 3 gal Wild Cat, and 1 gal Omega all of them are 15% nitro.
This mix yields 17.6% oil (1% castor. 16.6% synthetic), 15% nitro, 67.4% methanol (these numbers are rounded to the tenth).
