prevents engine damage.
F u e l re comm end ati on
The fuel recommended for your veh ic le is unle ad ed pr em ium grade
gaso line . See
a lso => page 378, "Data". Audi recommends using TOP
T IER Detergent Gaso line with a minimum octane rating of 91 AKI (95
RON). For more informat io n on TOP TIER Detergent Gaso line, please
go to the official website (www .toptiergas .com).
The recommended gasoline octane rating for your engine can also be found on a label located on the i nside of the fuel fi ller flap. This
rating may be specified as A KI or RON .
You r veh ic le may also be operated us ing unleaded regular gasoline
with a minimum octane rating of 87 AKl/91 RO N. However , using 87
A Kl /9 1 RON octane fuel w ill sl ightly reduce engine performance.

throughout the USA, Canada, and in most European countries. We
recommend that you do not ta ke your vehicle to areas or countr ies
where un le aded gasoline may not be available .

damaging "knock" caused by premature ign ition and detonation.
Therefore, buying t he correct grade of gaso line is very important to
help prevent possible engine damage and a loss of engine perfor ­
mance.
