Some use a lot of oil,some use very little.
The amount used early on is often a little higher than after everything is run in,and the rings etc are bedded in properly,but either way,you haven't got excessive oil usage,and as Gazwould rightly points out above,it is worth checking the oil level from time to time,rather than relying on the low oil level warning.
Another slightly strange point(although someone will know the answer to this)....the type of oil used can make a difference to oil consumption.
I've recently switched from Shell Helix to Motul 300V,and the consumption has dropped significantly,maybe due to lower degradation etc etc.
I'm not suggesting for a minute that you switch to something that costly,but it's an interesting finding.
