I was worried about my oil level on the digital gauge too, as mine got to the minimum. Bought 1L of oil, and used 500ml which brought it all the way to MAX! So it seems it's not a huge amount, just a prompt to top up a touch. Just had my oil changed and the digital gauge was 3/4, I'd rather have slightly less than too much oil.
EDIT: I should add I did provide my own oil Castrol EDGE 2x4L, and there was some left over so it definitely, took around 7-7.5L
