If it's a newer Bonneville (1999-200?), then it's 5w30. Anything older than that usually takes 10w30. In any case, you can use either one. I would go with the 5w30 because it services both your top and bottom end of your engine and is better for it in the long run. I would also recommend using a full synthetic or a blend as well to keep down the deposits and keep power in the engine.
A 1996 Pontiac Bonneville requires 5.7 quarts of oil in the crankcase. The oil filter should also be changed with the oil.
I had a 1997 Pontiac Bonneville which lost oil and had a piston go through the engine..bummer! I really liked the car and want to get another one, does this type of car usually burn oil or was it just this car?
