I bought my Chevy G20 van new in Nov. 1975 and we're still using it to carry the large loads or for hauling trailers. It has a 350 engine and a 4 barrel carburetor and only gets 10 mpg. Interestingly, while pulling our 23' travel trailer, the van still burned 10 mpg!
The 1985 Chevy Van 30 with a 5.7-liter engine typically achieves around 10 to 15 miles per gallon (mpg), depending on driving conditions and maintenance. Factors such as load, terrain, and driving habits can also influence fuel efficiency. Overall, this van is not known for its fuel economy, as it was designed more for capacity and utility than for efficiency.
