may be specified as AKI o r RON .
Yo ur vehicle may a lso be opera ted u sing unle aded reg ula r gaso line
w ith a minim um octane rating of 87 AKI/91 RON. However, using 87
AKI/91 RON octane fue l will slig htly reduce engi ne pe rformance.

Octane rating
Octane r atin g indica tes a gaso line's ability to resis t eng ine dam ag ing
"knock" caused by premature ignition and detonatio n. Therefore,
buying the co rr ec t gr ade o f gas oline is very im port an t to help prevent
poss ible engine damage and a loss of engi ne performance .
Gaso line most common ly used in the United States and Canada has
the following octa ne rat ings that can usually be fou nd on the filler
pump: •
Premium Grade : 9 1 -96 AKI
• Regu lar Grade: 87 - 90 AKI
E xp lanation o f the a bbrev iations:
AKI= Anti Knock Index= (R +M)/2 = (RON+MON)/2
RON= Resea rch Octane Number
M ON= M otor Octane Number.
(D Note
• Do not use any f uel w ith oc tane ra tings lower than 87 AKI or 91
RO N othe rw ise ex pensive engine damage will occu r.
