    Calais — N-body (1985–1991)
    • 1989–1991 Single-source

      shared N-body code; 160 hp, replaced the 3.0L V6; Wikipedia's Buick V6 engine article names the 3300 as LG7 and lists the Calais for 1989–1991, and the Calais article's engine list gives the 3300 for the same years (not independent); gnttype.org's Buick tables do not print it

    Cutlass Ciera — A-body (1982–1996)
    • 1989–1993 Single-source

      Wikipedia's Ciera table gives the Buick 3300 V6 for 1989–1993 (its infobox labels the engine LG7); its Buick V6 article ("3300 (LG7)" section) lists the Ciera 1989–1993; both are Wikipedia

    This page aggregates every documented appearance of LG7 in the Oldsmobile reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
