ing may be specif ied as AK I or RO N.
Your veh icle may also be operated using un­
l eaded regular gasoline with a minimum oc ­
tane rating of 87 AKI/91 RO N. However, using
87 A KI/91 RON octa ne fue l wi ll slightly re ­

Octane rating
Octane rating ind icates a gaso line's abili ty to
res ist eng ine dam ag ing "knoc k" ca use d by
premature ign ition and detona tion. Therefore,
buy ing the correct grade of gaso line is very
important to he lp prevent possible engine
damage and a loss of engine performance.
Gasoline mos t commonly used in the Unite d
States and Canada has the following octane r
atings t hat can usu a lly be found on the fi ller
pump:
- Premium Gra de: 91 -96 A KI
- Regular Grade : 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti K nock In d ex = (R+M )/2 = (RON
+ MON)/2
R ON= Resear ch Octane Numb er
MON = Motor Octane Num ber .
(D Note
-Do not use a ny fue l w it h o ctane rat ings
lower tha n 87 A KI or 91 RO N othe rwise
expensive engi ne damage w ill occur.
- Do
not use leaded gasoli ne. The use of
leaded gasoline w ill severely damage
yo ur v ehicle's cata lytic co nve rter and its

- fuel may have a considerably lowe r octane
rating. Improper fuel may cause engine
damage ;
- service may be inadequate due to lack of
proper service facilities, tools or testing
equipment ;
- replacement pa rts may not be readily availa­
ble.
- Navigation systems for vehicles built for the
U.S.A. and Canada will not necessar ily work
