wi th a m inimum octane ra ting o f 91 A KI ( 95
RO N). Fo r more informa tio n o n TOP TIER De

87 A KI/91 RON octa ne fue l wi ll slightly re

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
ability to co ntrol exha ust em issions .

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 10%

cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injuries.
- Fai lure to shut the engine off while refu
eling and/or to insert the pump nozzle
fully into the fuel filter neck could cause
fuel to spray out of filler neck or to over
flow. Fuel spray and overflowing fuel can
cause a fire.
