Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1978 G30.
The 1978 Chevrolet G30 anchors the front of a model-year file whose most useful context comes from a thirteen-year complaint record spanning 1990 to 2002. That dataset shows reports clustering in 1995 at 26 complaints — the high point of the window — before tapering to a single complaint by 2002, a steep decline that places the 1978 model year at the leading edge of a falling curve rather than at a static position in the model's history. For a researcher, the takeaway is structural: the G30's reputation, as captured in these filings, moved from frequently flagged to nearly silent within little more than a decade, and that arc is what gives the 1978 entry its place in the broader reliability narrative.
