you'll have to be more specific. there is alot of variables to take into consideration. like is the car running well, compared to what other sort of vehicle, what type of fuel, type of driving done, air conditioning being used, force fed (turbo) ect....
Additional answer
Often bigger engines will use less fuel, because they find it easier to do the work. Also, more modern engines often use less fuel than older ones that may be smaller.

What is the difference between a 2.5 and 3.5 Liter engine?
2.5 liter engine is smaller and more fuel efficient. 3.5 liter engine is a strong engine with better acceleration, but is less fuel efficient
How cars have changed 1940s-1980s?
its mainly build quality and engine output. a 1940s car with a 2 liter engine might have had 50bhp where as a 1980s car with a 2 liter engine might have had 80 to 90bhp. also later cars have more safety features and are far more reliable.
What are the best priced fuel efficient luxury cars?
When it comes to fuel efficient and luxury cars the best bet is to compare hybrid-engine designs. More and more luxury car companies are now coming out with fuel efficient hybrid-engine designs.
Why are cars with big engines a problem?
As the Engine capacity/size increases it is unavoidable that the rest of the engine has to increase in size to cope with the larger forces the larger engine capacity produces. This has the unavoidable effect of increasing friction, and reducing Fuel Efficiency. Hence a 4 liter engine will use more fuel than a 2 liter engine if all other things such as: Technology, weight of vehicle, driving style, fuel type etc are the same. Having a vehicle capable of 180MPH, that does 15MPG is regarded as "a problem" by some when the speed limit is 55MPH and a vehicle capable of 100MPH will do 60MPG. **Cars with big engines are considered a problem because it uses more fuel and creates bigger emissions.
Do diesel cars generally cost more than gasoline engine cars?
Diesel cars do tend to cost more in general than gasoline engine cars. The claim on this is that it is more expensive to create and manufacture these vehicles, and due the fact that diesel vehicles are more fuel efficient.
Why is bigger car make more pollution?
The engine in bigger cars are larger than of small cars as their engine is made up for heavy works.The cars engine powers denoted as CC (Cubic centimeters) as the power increases the engine uses more fuel, so it creates more pollution.
What will happen in the engine if the air cleaner is too dirty?
In older cars you will use more fuel. In new cars you will loose power.
Choosing a Fuel Efficient Car?
People often think of compact cars when they consider fuel efficient cars. But there are many midsize cars and SUVs that are fuel efficient. In choosing a car that will have good gas mileage, also consider the size of the engine and the vehicle size. An engine that is too small for the size of the vehicle may save you on fuel but cost more on engine repair or replacement.
If a car has a 3 liter engine does this mean that it has a higher top speed of a 2 liter engine or does is just mean that it can hold more fuel?
To answer your two-part question: Not always and no. A 3-liter engine is a larger engine than a 2 liter. The size is determined by calculating the volume of each cylinder and multiplying that value by the number of cylinders the engine has. An engine is essentially a pump. Since a larger engine can pump more air/fuel mixture, than it can make more power which will provide a higher top speed, unless other factors interfere (speed limiter, etc) A car with a larger engine cannot 'hold' more fuel. fuel is 'held' in the gas tank. back in the '50s & '60s it was pretty easy to figure out that cars that had more displacement (cubic inches) had more power. Because of advances in engine design, this is no longer the case. Variations in compression ratio, force induction (supercharger & turbochargers) can make a small displacement engine put out more power than a large displacement engine. These days it's entirely possible for a small hatchback with a 4 cylinder engine with less than 1.6 liters to put out more power than a V8 with over 5 liters.
Do trucks give out more CO2 than cars with the same engine?
Yes - as the body is heavier and they burn more fuel.
What is the fuel pressure specification for Chevrolet Vortec 6.0 liter 2002 engine?
55 to 62 PSI. No less and no more.
Where is the fuel pump located on a 1993 Ford E350 Ambulance with a 7.3 liter diesel engine?
You need to be more clear as to which "fuel pump" your wanting to know about. The Fuel Injection Pump, or the Fuel Lift Pump ??!!??!!
