Does Mileage of a car effects the gas mileage.?

Question

Does any one know, if a car, one with high mileage and one with low mileage would give different gas mileage and economy.

Answer 1

It's hard to say w/o knowing the condition to the high milage car. a brand new car has a tighter engine and won't get its optimal mileage until about 5-6000 km when the engine has been "worn in".


If given proper maintenance and tune ups when nesecary a car w/100,000 miles on it technicaly should get the same mileage as the same make and model car with 30,000 miles on it.

as far as economy is concerned:

newer cars - w/ low mileage cost more and are low maintenace

older cars - w/ high mileagecost conciderably less but have potential for higher maintenance costs.

it's pretty much up the the consumer because when you are buying a car for half the price of the same make and model car but w/ double the mileage, the maintenance cost's will not likeley exceed the initial price of the car, making the high mileage car cheaper.

milage also depends on hundreds of factors as well like tire size, air filters, exhaust isues, tire air pressures. ect. ect. ect.

Answer 2

The fuel consumption of a car should be the same on a car of any mileage so long as the car is well serviced. Although on a brand new car you need to run it in for 1000 miles before its able to give peak efficiency

Answer 3

Some cars with high mileage that the engine has not been serviced properly can have poor gas mileage. Like the oil and tranny fluid, air filters and fuel filters changed on a regular basis!

But if a car has been taken care of properly then you should be good.

Answer 4

A CAI(cold air intake)is installed away from the heat of the engine.It consist of an open filter which allows for a colder more dense charge of air that contains more oxygen to enter the the cylinders to be burned.Usually you will get better results out of your CAI after adding additional mods to your vehicle.If your vehicle is bone stock look to pick up around 2-3 hp.It seems you are more concerned with fuel economy than power so my advice to you is scratch the CAI.Do a simple tune up on your vehicle,if it has not been done in awhile.Simply replacing a dirty air filter,fuel filter,pcv valve,spark plugs,wires,and haing your injectors cleaned can increase fuel economy substantially.In addition,something as simple as adjusting the air in your tire to specs is another small benefit to mileage.

Answer 5

If you are running on Gas then as the price is half that of petrol I would not think that it would matter much. However as the engine ages it frees up and should get better until the wear in the cylinder allows the compression to drop when it will effect consumption a very little.

Answer 6

As a car puts more mileage on it it in turn will suffer gradually form wear to its engine components plus lose a small amount of power, this in turn will result in it not doing the same amount of mpg as a newer car.

In other words YES

Answer 7

yes it dos , but not for the reasins you might think. A brand new car's engine will always perform better than an old model of the exact age and model...reason being....wear and tear..! I had a thirty year old ford mark 1 and you didnt even have to giuve it a half turn of the key to see it was still brilliant......It far outlasted us.... We had to put it in the dump before the engine was even broken because more mew and upcoming things were in the island. Milage defi8nately does not affecty the car as long as you look after the engine... LOVE>>>>Das

Answer 8

Yes it would because the more worn the engine is and dirtier the engine is the less gas mileage you will get.

Answer 9

yes, a high mileage engine, due to wear, tends to use more oil and fuel than a new one.

Answer 10

Most certainly!
Wear and tear of the engine affects the efficiency of the combustion, thus giving a poorer mpg
