My habit is 3K-ish. A great many will run synthetic oil for really long intervals, while changing the filter and replacing that volume about every 3k.

Total volume is about 10 liters, or 11quarts. I once brain-cramped the whole 3 gallons into the crank-case with no obvious ill effect, but a proper fill is only 11, not 12, quarts.
