- 1984–1988 Disputed
the code Wikipedia's Ciera engine table prints for the 3.8 L V6 in 1984–1988; Wikipedia's Buick V6 article gives LG2 to VIN code B at 140 hp, not to the 125 and 150 hp figures the Ciera table lists; the Ciera infobox labels the 3.8 L engine LG3, so the article itself prints both codes; see LG3
