The 1989 GMC Safari, a full-size van, typically returns about 18 miles per gallon combined in everyday driving, with roughly 15–17 mpg in the city and 20–22 mpg on the highway. Actual figures vary depending on configuration, load, and maintenance.
Powertrain and efficiency by configuration
The Safari during this period was most commonly equipped with a 4.3-liter V6 engine paired to an automatic transmission. Two-wheel drive was the standard setup, with heavier payloads and wear over time potentially reducing efficiency. The mileage figures reflect the technology and weight of late 1980s GM vans rather than modern fuel-management systems.
EPA estimates and real-world observations
EPA estimates for the typical 4.3L V6 with automatic transmission in 1989 vans hovered around 15–17 miles per gallon in city driving and about 20–22 miles per gallon on the highway. In practical, mixed-use driving, owners often reported combined figures around 18–19 mpg. Real-world results can vary widely due to maintenance, load, tire condition, and driving style.
Factors that affect MPG
Several variables influence the actual MPG you’ll experience with a 1989 Safari, including engine health, transmission wear, tire pressure and type, cargo load, and how the vehicle is driven.
Tips to maximize fuel efficiency on a vintage van
To squeeze a bit more efficiency from a late-1980s van like the Safari, consider these practical steps.
- Keep the engine well-tuned and use the correct spark plugs and filters.
- Maintain proper tire pressure and alignment.
- Reduce unnecessary weight and remove roof racks when not in use.
- Plan routes to minimize idling and stop-and-go driving; use steady highway speeds when possible.
- Adopt a smooth driving style—anticipate stops and accelerate gradually.
- Limit air conditioning use on long highway trips if weather allows.
These practices won't transform a late-1980s van into a modern gas-sipper, but they can help offset some of the era's efficiency drawbacks.
Summary
The 1989 GMC Safari’s fuel economy sits in the high-teens for typical mixed driving, with EPA-era estimates around 15–17 mpg city and 20–22 mpg highway for the common 4.3L V6 with an automatic transmission. Real-world results vary with condition, load, and driving habits. With regular maintenance and thoughtful driving, you can maximize the van’s efficiency within the constraints of its era.
