Not typically.
It depends on the vehicle, Large pickups and SUVs with small engines tend to get worse mileage than the same type of vehicle with a larger engine, especially in hills and when towing. The smaller engines have to work much harder for similar results. In cars a V6 Buick can achieve better economy than a 4 banger Honda, it all depends on the manufacture and engines http://fueleconomy.gov/ is a great site to compare cars and engines for economy
It is the volume of fuel the cylinder (and piston) of an engine can take! Generally, higher is more horsepower and lower is better fuel economy
Performance chips provide a horsepower boost to your vehicle. Some of them also provide better fuel economy.
Go easy on the brakes and accelerate slowly. This is why highway fuel economy is better than city in vehicles.
The 2006 Dodge Charger is much better than the Acura TL given its good fuel economy and horsepower.
For a better "burn" of the air fuel mixture. More power, better economy, lower emissions.For a better "burn" of the air fuel mixture. More power, better economy, lower emissions.
It improvea the horsepower, torque and the fuel economy of a car.
The throttle body spacer is a small piece of metal that is attached the back of a throttle body. It is suppose to change the airflow which can potentially give you more horsepower and better fuel economy.
No.
in my opinion fuel injection is better because it increases your horsepower and gas mileage in most cases
My site has quite a bit of info relating to this http://www.maintainyourcar.com/ It depends on what car gives better fuel economy. Some cars that were designed to run on higher octane will give you better performance when using the correct fuel and your fuel economy. Check with your manufacturer. With a Mercury Cougar You could try 91 octane or 95 octane, at least 91 octane will give you a bit better economy Consider servicing the car too that can help!
better fuel economy, and its better for your engine trans etc
Yes
