Every Jeep Comanche engine, compared
Picking the right version of the same car often saves more fuel than picking a different car altogether. Yearly cost assumes 12,000 miles at $3.20 a gallon.
| Engine | Combined | City / Highway | Years | Fuel per year |
|---|---|---|---|---|
| 2.1L 4-cyl | 24 / 28 | 1986–1987 | $1,506 | |
| 2.5L 4-cyl | 18.6 / 22.4 | 1988–1992 | $1,882 | |

| 2.8L 6-cyl | 15 / 20 | 1986–1986 | $2,259 |
What that actually costs
Miles per gallon is an abstraction; the fuel bill is not. Here it is in money, at 12,000 miles a year and $3.20 a gallon.
| Measure | Value |
|---|---|
| Cost per mile | $0.162 |
| Fuel per year | $1,949 |
| Fuel over five years | $9,745 |
| Against other 4-cyl cars | +$437 a year |
| EPA's own estimate | $3,200 a year |
City or highway — who is this car for
The gap between city and highway figures tells you whom the car suits. A wide gap punishes stop-and-start traffic; a narrow one means the car doesn't care where you drive it.
| Measure | Value | Reading |
|---|---|---|
| City | 17.8 mpg | $2,157 a year if you only drive in town |
| Highway | 22.4 mpg | $1,714 a year if you mostly commute |
| Gap | +4.6 mpg (26%) | Typical for its type |
How the Comanche changed over the years
Combined figure by model year. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.

How we count
Fuel-economy figures come from EPA fueleconomy.gov — the same laboratory numbers printed on the window sticker. We don't adjust them; real-world consumption depends on how and where you drive.
What we add is money. Yearly cost assumes 12,000 miles at $3.20 a gallon — change either and the ranking stays, only the size of the bill moves. Cost per mile is the same figure divided out, useful when comparing a commute against a weekend car.
