Octane Rating
The octane rating of a gasoline is a measure of
its resistanceto =knocking". Use a minimum of 87
octane bythe antiknock index is recommended.The
antiknockindex is posted on service stationpumps
in the IJ.S.A.
NOTE
Off "knocking or pinging'occurs, use a different
brand of gasolineor higheroctane rating.
Oxygenated Fuel
Oxygenates (either ethanol or MTBE) are added
to the gasoline. If you use the oxygenatedfuel be
sure it is unleaded and meets the minimumoctane
ratingrequirement.
The followingare the EPA approvedpercentages
of fuel oxygenates.
ETHANOL: (Ethyl or GrainAlcohol)
You may use gasoline containing up to 10%
ethanol by volume.
MTBE: (Methyl Tertiary ButylEther)
You may usegasolinecontainingupto 15% MTBE
by volume.

You may use gasoline containing up to 5%
methanol by volume, as long as it also contains
cosolventsand corms, ion inhibitorsto protectthe
