Whats the gas mileage on a 1994 Oldsmobile delta 88?

The gas mileage for a 1994 Oldsmobile Delta 88 varied depending on the engine and transmission. There wasn't a single figure. You'll find different numbers depending on the source, and real-world mileage will also vary based on driving habits and vehicle condition.

However, you can expect to see figures in the range of:

* City: 16-18 mpg (miles per gallon)

* Highway: 22-25 mpg

These are estimates. To get a more precise idea, you should consult the original owner's manual (if you have it) or look up fuel economy information based on the specific engine (e.g., 3.8L V6, or a different engine if equipped) on sites like the EPA's FuelEconomy.gov (though older vehicle data may be limited there).
