A badly tuned engine unnecessarily wastes a lot of fuel.
By having your vehicle regularly serviced by an authorized Audi dealer helps to ensure that it runs properly and economically. The condition of your vehicle not only affects its safety and ability to hold its value, it also affects fuel consumption.
Check your oil each time you fill your tank.
The amount of oil used is related to engine toad and speed.
It is normal for the oil consumption of a new engine to reach its lowest value after a certain mileage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly assess oil consumption.
This also applies to fuel consumption and engine output.
Note
Fewer short trips
Fuel consumption will always be relatively high on short trips.
The engine and catalytic converter have to reach their optimal operating temperature to reduce fuel consumption and noxious emissions effectively.
Just after starting, a cold engine in a mid-size car only achieves a fuel economy of 6-8 miles per gallon (30-40 1/100 km). After about a half a mile, fuel economy climbs to 12 mpg (20 l/l00 km). After about 2,5 miles (4 km), the engine is at its proper operating temperature and fuel economy has reached a normal level. So you can see that you should avoid short trips whenever possible.
The outside temperature is also critical in this regard. Your car consumes more fuel in the winter than in the summer.
