Oil Pressure Question

Well its official I'm an idiot!!

When the motor was warmed up I was down a full Liter of Oil (Thats a quart for you folks south of the border) 8) Topped her up and everything is back to normal. I guess all the oil in the block must have worked its way back down into the pan, giving me a false full.

I guess this motor is burning some oil, as it does not leak at all.
