Re: what is the meaning of car usage ?

This is just 'How much the car has been used'.  It is measured by saying how many miles are 'on the clock'.  Generally a second hand car will be better if its mileage is lower.

Re: what is the meaning of car usage ?

The dictionary defines efficiency as "minimum expenditure (of time and) effort".  In the case of car efficiency how well does the engine convert fuel into miles travelled.  A car is more efficient if it goes further for each gallon of fuel.

If you wanted to work out how efficient a car is,  measure how much fuel is needed for a given journey in miles.  Divide miles by gallons to get the measure in miles per gallon.
