Someone once told me for most cars the difference between max and min on the dipstick on most cars is 1 litre, so work it out from that.
The digital display is a low resolution... You could be "just" into the next graduation, or near the top of it if you see what I mean. Both are effectively the same, but when lower it induces more "porsche paranoia".
I usually try to keep my 996 at max. I want to actually see oil with my own eyes, not necessarily trust 18 year old sensors.
