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

alcohol o r MTBE (commonly referred to as
oxygenates) if the blende d mixture meets t he
f o llow ing criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti -kno ck index must be 87 A KI or higher.
- Blend must contain no more t han 3% meth-
anol.
- Blend must contain more than 2% co -sol -
vents.
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
- Anti -knock index must be 87 AKI or higher .
- Blend must not conta in mo re tha n 15%
