check your owners manual i belive its 5 quarts
always look in your owners manual. but I've driven and maintained a 90 91 93 buick century. if 6 cylinder i would suggest 4.4 litres or oil and change the oil filter at every oil change.
If it has a four cyl engine it takes 4 qts of oil, if its a v6 it takes 4.5 qts of oil.
The oil capacity for an oil and filter change is 4.5qts. If you choose to not change the filter it would only be 4.0qts of oil. qts=quarts.
The oil capacity is 4.56 quarts.
