1991 Ford Aerostar Wagon: MPG and fuel economy
The 1991 Ford Aerostar Wagon is rated by the U.S. Environmental Protection Agency at 18 combined MPG, with 16 MPG in the city and 22 MPG on the highway. That puts it well above the average for cars in the Vans class in the same model year.
This page collects every fuel-economy figure the EPA publishes for the 1991 Ford Aerostar Wagon. Below you will find the headline combined, city, and highway MPG, the estimated annual fuel cost at three different driving levels, the tailpipe CO₂ emissions, and a full breakdown of the engine and drivetrain. The EPA rates 3 separate variants of this car (different engine, transmission, or drivetrain combinations), and you can compare them side by side in the trims table. If you want to know whether this generation got more or less efficient over the years, the year-over-year table further down covers every model year the EPA has rated.
Key takeaways
- The Ford Aerostar Wagon has lost 5 MPG since its first rated model year, the 1986 Ford Aerostar Wagon at 22 MPG. That is often a sign of larger engines or heavier curb weights in newer generations.
- EPA estimates this car costs around $5,750 more in fuel over five years than an average new vehicle of the same model year.
Fuel economy at a glance
These are the EPA's official ratings for the 1991 Ford Aerostar Wagon. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.
When the EPA tests several variants of the same nameplate (for example, a front-wheel-drive version and an all-wheel-drive version), each gets its own rating. The figures shown here are the headline variant, taken as the configuration with the best combined MPG. The trims table further down covers all 3 variants side by side.
Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).
| Combined MPG | 18 MPG |
| City MPG | 16 MPG |
| Highway MPG | 22 MPG |
| Annual fuel cost | $3,300 |
| Tailpipe CO₂ | 494 g/mi |
| Fuel type | Regular |
How the 1991 Ford Aerostar Wagon compares
The 1991 Ford Aerostar Wagon returns 18 combined MPG. Cars in the Vans class for the same model year average 15.5 MPG, which puts this car ahead of the class average by about 16%.
For broader context, the average new car of the 1991 model year (across all classes) returns 18.7 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 1991 model year is on its own page.
Trim variants rated for 1991
The EPA rates 3 separate variants of the 1991 Ford Aerostar Wagon. The differences come from the engine size, transmission type, and drivetrain (front-wheel drive, all-wheel drive, and so on). The same nameplate can land several MPG apart depending on the configuration you actually buy.
| Engine and transmission | Drive | Combined | City | Highway | Annual cost |
|---|---|---|---|---|---|
| 3L, 6-cyl, Manual 5-spd | Rear-Wheel Drive | 18 MPG | 16 MPG | 22 MPG | $3,300 |
| 3L, 6-cyl, Automatic 4-spd | Rear-Wheel Drive | 17 MPG | 15 MPG | 21 MPG | $3,500 |
| 4L, 6-cyl, Automatic 4-spd | Rear-Wheel Drive | 16 MPG | 15 MPG | 20 MPG | $3,750 |
Annual fuel cost across driving patterns
The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for regular gasoline, which is $3.99/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.
The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 833.3 gallons (the car's annual consumption at the rated MPG).
| Driving pattern | Estimated annual fuel cost |
|---|---|
| Light driver, 7,500 miles per year | $1,650 |
| Average driver, 15,000 miles per year | $3,300 |
| Heavy driver, 25,000 miles per year | $5,500 |
Year-over-year MPG for the Ford Aerostar Wagon
The EPA has rated the Ford Aerostar Wagon across 12 model years, from 1986 Ford Aerostar Wagon through 1997 Ford Aerostar Wagon. The numbers below are the best combined MPG figure the EPA published for each year, which lets you see when the car was at its most efficient and how recent generations stack up.
The 1986 Ford Aerostar Wagon returned 22 MPG. The most recent 1997 Ford Aerostar Wagon returns 17 MPG. That is a drop of 5 MPG over 11 model years. Newer trims that grow heavier or carry larger engines tend to lose efficiency even as the rest of the lineup improves.

Specifications
The 1991 Ford Aerostar Wagon runs a 3-liter 6-cylinder engine paired with a manual 5-spd, sending power through rear-wheel drive.
Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.
