Fewer short trips
Fuel consumption will always be relatively
high on short trips.
11-Try to avoid driving short distances with a
cold engine.
The engine and catalytic converter have to
reach their optimal
operating temperature to
reduce fuel consumption and noxious emis­
sions 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 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 tempera­
ture and fue l economy has reached a normal
l eve l. 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.

Fuel recommendation
The fuel recomme nded for you r vehicle is un­
lead ed premium
g rade gasoline . Audi recom­
mends using TO P TI ER D ete rgent Gaso line
wi th a minimum oc tane ra ting of 91 A KI ( 95
RON ). For more informa tio n o n TO P TIE R De­

website (www .to ptiergas .com) .
Th e re commended gasoline o ctane rating for
your eng ine can also be fo un d o n a label loc at­
ed on the ins ide of the fue l filler flap . This ra t­
in g may be specified as AKI or RON.
Your veh icle may also be operated using un­
l e ad ed regular g asoline with a min imum o c­
tane rating o f 87 AKI/9 1 RO N. H owever, using
87 AKI/91 RO N octane fue l w ill slightly re­
d uce eng ine perfo rmance .
Use unleaded ga soline only. Unleaded g aso­
li ne is availab le th rougho ut the USA, Canada,
and in most E uropean countries . We recom­
mend that you do not ta ke yo ur vehicle to
areas or countries where unleaded gasoline
may not be ava ilable.

Octane rating
Octane rating ind icates a gaso line' s abili ty to
r es ist eng ine da mag in g "kno ck" cau sed b y
p rem ature ign ition and detona tion. Therefore,
b uying the correct grade of gasoline is very
important to he lp prevent possible engi ne
damage and a loss o f engine performance.
Gasoline mos t commonly used in the Unite d
States an d Canada has the following octane
rat ings that can usually be fo und on the filler
p ump : -
Premium Grade: 9 1 -96 AKI
- Regular Gra de: 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti Knock In d ex = (R+ M)/2 = (RO N
+ MO N)/2
R ON = Research Octane Number
MON = Moto r Octane Number .
@ Note
-Do not use a ny fue l w it h octane rat ings
