The Dodge OMNI does 27.3 mpg combined (23.9 city, 33.0 highway), which works out to about $1,407 a year in fuel at $3.20 a gallon and 12,000 miles. Engine choice matters more than you'd think: 1.6L 4-cyl does 30 mpg while 2.2L 4-cyl does 25.3 — a difference of $238 a year. Against other 4-cyl cars it sits above the average of 25.4 mpg.
Every Dodge OMNI 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 |
|---|---|---|---|---|
| 1.6L 4-cyl | 26 / 35.3 | 1984–1986 | $1,280 | |
| 2.2L 4-cyl | 22.3 / 31.3 | 1987–1990 | $1,518 |
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 | $0.117 |
| Fuel per year | $1,407 |
| Fuel over five years | $7,035 |
| Against other 4-cyl cars | −$105 a year |
| EPA's own estimate | $2,314 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 | 23.9 mpg | $1,607 a year if you only drive in town |
| Highway | 33.0 mpg | $1,164 a year if you mostly commute |
| Gap | +9.1 mpg (38%) | Wide — this car dislikes traffic |
How the OMNI 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.
| Model year | Combined | City / Highway | Engines offered | Fuel per year |
|---|---|---|---|---|
| 1990 | 22 / 31 | 1 | $1,536 | |
| 1989 | 23 / 32 | 1 | $1,477 | |
| 1988 | 22 / 31 | 1 | $1,536 | |
| 1987 | 22 / 31 | 1 | $1,536 | |
| 1986 | 26 / 35 | 1 | $1,280 | |
| 1985 | 26 / 36 | 1 | $1,280 | |
| 1984 | 26 / 35 | 1 | $1,280 |

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.
