What is the mpg on a 1987 Subaru GL?
The 1987 Subaru GL typically delivered fuel economy in the mid-20s to low-30s miles per gallon, with exact numbers depending on engine size, transmission, and whether the car was two-wheel-drive or all-wheel-drive.
Understanding these figures requires considering the era’s testing methods, the specific configuration of the GL, and how maintenance, driving style, and conditions affect real-world mileage today.
mpg ranges by configuration
Before listing typical figures, note that 1980s EPA ratings differ from modern ones and actual mileage depends on maintenance and driving style. The following ranges reflect common experiences among owners and period estimates for common GL setups:
- Two-wheel drive (2WD) with a manual transmission: approximately 28–32 mpg on the highway and about 22–25 mpg in city driving, with a combined figure around 25–28 mpg.
- Two-wheel drive (2WD) with an automatic transmission: typically around 25–30 mpg highway and 20–24 mpg city, for a combined roughly 23–26 mpg.
- All-wheel drive (AWD/4WD) with a manual transmission: added weight reduces efficiency, roughly 25–30 mpg highway and 19–24 mpg city, for a combined around 23–26 mpg.
- All-wheel drive (AWD/4WD) with an automatic transmission: generally the least efficient configuration, about 25–28 mpg highway and 18–23 mpg city, for a combined around 22–26 mpg.
These ranges summarize typical observed values and official-era estimates; individual cars can vary based on engine condition, tires, load, and driving style.
Historical context and real-world expectations
In the 1980s, EPA testing and reporting differed from today, and many owners relied on highway figures or real-world observations. A well-maintained GL today—especially a 2WD manual model—can approach the higher end of these ranges, while city-heavy driving or a heavier AWD setup will trend toward the lower end.
To maximize mileage in a vintage GL, focus on regular maintenance, properly inflated tires, clean air filters, and smooth acceleration and steady cruising speeds.
Where to find authentic numbers and maintenance tips
Original brochures and period publications sometimes list EPA estimates, while modern forums and restoration resources may share owner-reported figures for specific configurations.
Summary: The mpg of a 1987 Subaru GL varies by configuration, but most setups fall in the mid-20s to low-30s mpg range. Manual transmissions and 2WD typically yield higher efficiency than automatics and AWD, and real-world mileage will depend on maintenance and driving style.
