4.5 to 4.75qts
When changing the oil or oil filter of a car, it is important to know the cars oil capacity. For a 1997 Oldsmobile Bravada, its oil capacity is 4.50-4.75 quarts of oil.
the 4.2L takes 6.6 litters or 7 quarts of oil
I have a 2002 Oldsmobile bravada and we changed the oil today it took about 7-8 quarts.
The oil capacity is 7quarts
On my 1994 Bravada the oil filter is located behind the driver side headlight, if the 1991 has an oil cooler like the 94 it is probably there also. You might also ask at this forum I have found useful http://www.gminsidenews.com/forums
