Oil pressure?

That is the same way my car behaves once it has been started, 5 bar at 
start, 5 bar when I'm on the gas and 2 bar at idle once its warmed up. 
Even after this weirdness the last few days. Just seems odd that all of 
a sudden its behavior changes, not to mention the oil warning keeps 
going off despite having a full oil level.

I agree with Ed as well, I don't really think the needle's initial 
position means all that much. It's more that I'm curious why it would 
randomly change from showing 5 bar, to showing 1 bar and telling me the 
oil is low when, in reality, it has a full crankcase of oil.

As for the the oil consumption, yes it is high. If you search the 
archives for posts from 'Derek Pulvino' you will see he has asked about 
this issue before. Turbo seals among other things were suggested, 
although I noticed a coating of oil on the back of the engine and the 
bottom part of the distributor which garnered a raised eyebrow from me.
