I find that when I check the engine oil the dip stick shows alevel between the two marks, if I then dip it again the level is below the lowest mark. A local mechanic told me that this is normal on some french cars and a small reservoir that the dip stick goes into that needs to refill.
I think I must have over filled recently which caused a leak from the sump.
