Documented applications

Park Avenue — C-body (1991–1996)

1992–1996 Single-source

Ultra only; the Series I engine for 1992–1995 (205 hp to 1993, 225 hp for 1994–1995) and the Series II for 1996 (240 hp); 1992–1996 from Wikipedia's Park Avenue infobox and its Buick V6 article; 1991 is left out because the Park Avenue article's text gives the Ultra the supercharged engine only from 1992, while its infobox and the V6 article start it in 1991; shared C-body engine: the Oldsmobile 98 article and the V6 article date the sibling Ninety Eight's supercharged engine 1992–1995, which supports no Park Avenue year beyond the row's, and both are Wikipedia, so the row stays single-source

Park Avenue — G-body (1997–2005)

1998–2005 Factory-verified

The 2003 list reads sequential fuel injection (SFI); the other lists read multiport. TriShield agrees on the meaning (multiport). Wikipedia: only Ultra models were supercharged.
