* Specific engine: Even within the 5.7L V8 designation, there were variations in the engine that affected MPG.
* Transmission: Automatic or manual transmission significantly impacts fuel efficiency.
* Vehicle weight: A G30 could be configured in various ways, altering its weight and MPG. The presence of additional equipment or cargo heavily impacts fuel consumption.
* Driving style: Aggressive acceleration and high speeds drastically reduce MPG.
* Maintenance: Proper maintenance keeps the engine running efficiently.
* Terrain and driving conditions: City driving yields lower MPG than highway driving.
Therefore, you won't find a precise MPG number. To get an estimate, you'd need to consult resources like:
* The owner's manual: This might have an EPA estimated MPG, but keep in mind this is an ideal and real-world results will vary.
* Online forums: Searching for "1995 Chevy G30 5.7L MPG" on forums dedicated to classic Chevy vans might yield real-world reports from owners.
* EPA fuel economy website (archive): The EPA website may have archived fuel economy data for that model year, though it might not be perfectly specific to the 5.7L V8.
Expect the MPG to be relatively low compared to modern vehicles, likely in the range of 8-14 MPG (or even lower depending on the factors above). This is just a rough estimate.
