Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.

Have your vehicle serviced at regular intervals.
By having your vehicle regu larly serviced by an
author ized Audi dealer he lps to ensure that it
runs properly and econom ically

The condition of
your veh icle not only affects its safety and ability
to hold its value, it also affects

The amount of oil used is re lated to engine load

· Fewer short trips
Fuel consumption will always be relatively high
on short trips
.
.,.
Try to avoid driving short distances with a cold
eng ine
.
The eng ine and catalytic converter have to reac
h
their opt imal
operating temper atu
re to reduce
fuel consumpt ion and noxious emiss ions effec-
tively
.
Just after start ing, a cold engine in a mid-size car
on ly achieves a fuel economy of 6-8 miles per
gallon (30-40 l/100 km)
.
After about a half a
mile, fuel economy climbs to 12 mpg (20 l/100
km)
.
After about 2.5 m iles (4 km), the engine is
at its proper operating temperatu re and fuel
economy has reached a no rma
l
level. So you can
see that you should avoid sho rt tr ips wheneve
