I have a 1987 camaro with a 350 cubic inch motor (5.7 liters) that gets about eight miles to the gallon. That's pretty average for a high performance muscle car.
If you take care of your car it can go easily 200k.
Simply put, the higher the mileage the less the value.
A free flow muffler can improve mileage but by not by much. It would take a long time to recoup the cost of a new muffler.
There is only one thing to do if your car is not showing the mileage. You should take it in the to the dealership and have it fixed.
As in gas mileage. you take how many miles you can drive on a full tank and divide it by how much your gas tank can hold in gallons and then it should give you your miles per gallon.
Efficiency is like a ratio. The higher the efficiency the less you have to put in or the more you get out. Performance is just how fast or how much it can make of something. Example: A hybrid car has a high efficiency because you get more mileage than say a muscle car, but the muscle car has higher performance because it goes faster and has more power.
The car rental service includes 100 miles of free mileage per day.
Roof racks themselves have a negligible effect on gas mileage.
You have to change your oil as directed to keep your car from becoming useless.The mileage is secondary.Primarily you want your car to be functional and not scrap metal.
If the car was taken care of and serviced regularly then this is not really high mileage. It is not low mileage either. Expect to spend money on some repairs on a car with this mileage. If the car has been neglected then this is high mileage.
The mileage is how many miles the car has travelled, the total mileage is shown on the speedometer dial.
Yes, they will provide, but make sure that mileage is genuine or not. There is much free mileage checker available online for free. Try them with the used car vehicle registration number and once again verify it with the mileage check report. It will let you know whether it has any mileage discrepancy or not.
